Visual Basic USB sample and generated code: Fixed the default alternate setting number in the generated code which was previously set to the selected interface number (since v6.0.0).
Visual Basic USB sample and generated code: Fixed flawed implementation of ListenToPipe() function and related functions, due to lack of good support for multi-threading and CreateThread() in VB (specifically VB 6.0). ThreadStart/Stop() Visual Basic functions are now replaced with VB_ThreadLoopStart/Stop() DLL functions and Listen loop runs in the DLL (not in the user thread function).
Delphi USB: Previously, in PrintEndpoints() function in usb_diag_lib.pas sample, endpoints data was inaccurate and the application terminated if there were zero endpoints (since v6.0.0).
Delphi USB: Fixed DLL thread functions usage, resolved previous problems with Listen to Pipe function (since v6.0.0).
Linux 2.4: Resolved previous problem, where on some computers there was a failure in reading from the PCI card's memory (read only 0xffffffff). The problem is resolved by calling pci_enable_device() function.
Windows CE: Improved implementations of spinlock and events.
PLX samples: Resolved previous application error caused by read/write from local addresses due to miscalculation of dwMask (since v6.0.0).

Linux: Fixed problems related to simultaneous usage of WinDriver v6.0X and WinDriver v5.2.2 or lower on the same PC (since v6.0.0).
Wizard USB projects (*.wdp files): Disabled Save option. This option is no longer supported beginning with v6.0.0 (since it has no real significance), but was inadvertently still enabled in the wizard in v6.0.0-6.0.1 (since v6.0.0).
USB generated code: Solved the problem where code generated in v5.2.2 or lower and rebuilt with v6.0X failed to activate event_register() (since v6.0.0).
Windows: Previously (from v6.0.0), on rare occasions WD_UsbTransfer() and potentially WD_IntWait() returned incorrect error status/caused a system crash.
Windows: windrvr6.inf no longer demands an IRQ from Windows, and the memory range from which 1 byte was taken has been expanded, fixing WinDriver installation failure on some machines (since v6.0.0).
WDREG: Previous junk messages and WDREG crashes have been eliminated (since v6.0.0).
Visual Basic ISA code generation: Resolved previous compilation errors (bug since v6.0.0).

Windows: USB Transfer functions now return to the caller when short USB bulk / interrupt transfer arrives, instead of waiting for the entire buffer to be filled.
Windows CE: During CE startup, CE tried to load the wrong DLL (windrvr.dll instead of windrvr6.dll).
Windows 98: Copy newdev.dll to the user's computer, if it does not exist. (This DLL is required for detecting the connected USB devices and for installing INF files for these devices.)
Linux USB: Interrupt transfer could cause a crash due to incorrect pipe type detection in the case of transfer failure.
Linux USB: Linux occasionally returned incorrect error status.
Linux USB: Fixed handling of devices with multiple interfaces.
Visual Basic: Fixed Stat2Str() VB implementation (in wd_utils.cls) for correct handling of string transfers between C DLL and VB application.
Visual Basic USB: Corrected function declarations in wd_utils.cls.
Visual Basic PCI: Generated code: Fixed WD_License() call by adding a NULL character to the end of the license string that is sent to the function, so that it will be interpreted as an ANSI string by the C DLL.

WinDriver and KernelDriver documentation improved, including restructuring, many contents fixes and useful additions.

Fixes

Windows
- Fixed a bug in the WDREG utility, which caused to fail on Windows 95.
Linux
- Fixed the generated Kernel PlugIn makefile on Linux. Previously in some cases "make install" would install the wrong files. Also the makefile now identifies various problems during the installation and automatically fixes them.
USB

- Solved synchronization problem that sometimes cause BSOD with USB devices.

KernelDriver
- Fixed a bug in KernelDriver's function KD_OpenWinDriver() in kd.lib, on Win32 platforms. Previously only the first call to this function was successful, while consequent calls would fail.

Version 5.2.1 (Release Date: October 23, 2002)

Enhancements

Several transfer commands that acknowledge an interrupt/for interrupt acknowledgment can now be set in DriverWizard.
Improvement of Debug Monitor buffer overflow behavior, so that older messages are lost rather than new messages.
Added DMA_ALLOW_CACHE option to WD_DMALock(). It allows the locked memory on Windows NT, 2000 and XP to be cached to the CPU, thereby achieving a major increase in DMA speed (however it may cause data corruption).
WinDriver can now automatically install an INF file for a device which is not connected to the computer.
KernelDriver can now be loaded prior to loading WINDRVR.SYS.

Fixes

General
- Fixed a bug that caused memory corruption and BSOD on Win2000/XP, when performing contiguous DMA and calling WD_DMAUnlock().
- Fixed BSOD when KernelDriver calls WD_IntCount() from high IRQL (usually the function is called from windrvr_int_thread.h ISR).
- Fixed BSOD in cases when a LOT of interrupts (2\^31) are generated but no application/driver is registered to listen to them.
- Fixed a bug that caused a potential for BSOD on each call to the Kernel PlugIn (especially on checked build when using Microsoft Driver Verifier).
- Fixed a bug that caused Cypress EZ-USB firmware download to fail (especially if recompiled).
- Fixed bugs in the support for Visual Basic and Delphi, which caused compilation errors.
- Fixed Scatter/Gather DMA handling on Linux, which gave wrong byte count to first and last pages.
- Fixed a bug that caused the XXX_CountDevices() function in the USB generated code to fail.
- Fixed a bug in the Kernel PlugIn installation, which caused the Kernel PlugIn to fail to start after reboot.

Version 5.2.0 (Release Date: September 1, 2002)

New Features

Added Plug-and-Play and power management handling, both at the kernel and at the user level. This allows compliance with Windows Driver Model (WDM) functionality.

Version 5.0.5 (Release Date: May 5, 2002)

New Features

Added enhanced support for PLX Technology's new product line, the PCI 9056 I/O Accelerator chip. The enhanced support includes special set of API which implements PLX 9056 access and control, as well as sample application, which can be used as a skeletal driver.

Enhancements

Improved interrupt handling on Windows NT 4.0 running on a computer with APIC (Advanced Programmable Interrupt Controller) chip, by retrieving PCI related data from the OS instead of directly from the hardware.

Fixes

General
- Fixed a bug in DriverWizard that caused issuance of "The resource is overlapped with another resource" warning messages on wrong circumstances.
- Fixed a bug that, when using a kernel PlugIn, sometimes caused an interrupt not to be handled by the kernel PlugIn's DPC routine if the interrupt occurred immediately after it was enabled.
Windows
- Fixed a bug that caused BSOD when using the DriverWizard generated INF file on certain PCI devices (a bug since v5.0.4).
- Fixed the file KP_95.lib which was missing several functions required for compiling Kernel PlugIn projects under Windows 95 (a bug since version 5.0.4).

WinDriver Hardware Debugger now sends debug messages to the operating system's kernel debugger.
Added version information to wdpnp.sys that can be retrieved by reading the file properties.
WinDriver User's Guide now includes new, improved, function reference.

Enhancements

WinDriver for USB — New API: WD_UsbResetDeviceEx(), allows reset of devices that are not in disabled state.
WinDriver for USB — Added USB_SHORT_TRANSFER option to WD_UsbTransfer(). If set, the function will return successfully if a short packet (less than maximum packet size) was transferred, regardless as to whether the data buffer was filled.
WinDriver for USB — Added USB_FULL_TRANSFER option to WD_UsbTransfer(). If set, the function will return successfully if all the requested data was transferred.
Minimized quantity of warning messages — when compiling code generated by DriverWizard under warning level 4.
The descriptions and remarks embedded in the code generated by the DriverWizard were improved.

Fixes

PCI — General
- Access to EEPROM of PLX 9030, 9054 and IOP480 chipsets was improved. Now when access to EEPROM of these chipsets fails, WinDriver retries the entire access process.
- Interrupt handling by DriverWizard was fixed. A bug since version 5.0 caused DriverWizard to handle interrupts without implementing all the parameters assigned by the user; this affected level sensitive interrupt handling and data transfer operation type definition.
- Execution method of interrupts transfer commands was improved. Now the interrupt transfer commands are executed only if the application handling the interrupts exits abnormally. A bug since version 4.4.0 caused interrupts transfer commands to be executed each time the interrupt was disabled.
- Fixed a bug that caused WinDriver to issue application assertion under Windows 2000 checked-build.
- Fixed WD_MultiTransfer() to support Delphi.
- DriverWizard was fixed to disable generation of XXX_AccessRanges(hXXX) functions when the relevant PCI device has no I/O or memory resources at all. This bug caused compilation errors when trying to compile generated code for devices with no I/O or memory resources.
Windows NT 4.0 — PCI
- Fixed the support for interrupt handling on dual CPU platforms. Interrupt line and device resources information is now retrieved from the operating system (instead of directly from the hardware).
Windows 9x — PCI
- Set Auto Masking for non-sharable interrupts only. A bug since v4.4.2 could have caused WD_IntDisable(), when using sharable interrupts, to disable other interrupts as well.
Linux — General
- The operation of the function WD_DMALock() for contiguous DMA under Linux was fixed. The bug caused the function to reserve one extra page (if the allocation was page aligned). This resulted in kernel panic inside kfree() (which was observed when the following sequence was performed: lock, lock, free, free).
- Modified user makefiles for compilation under RedHat Linux 7.0 and above.
Windows — General
- Fixed a dependency problem between windrvr.sys and wdpnp.sys. A bug since version 5.0.3 caused windrvr to return error code 37 (STATUS_INTERNAL_ERROR) if wdpnp.sys was loaded before windrvr.sys/vxd. Now, the resource management is handled by wdpnp.sys instead of windrvr.sys/vxd and if windrvr.sys/vxd is loaded after wdpnp.sys, it will initiate the transfer of the card resources instead of wdpnp.sys.
  Moreover, now wdpnp.sys does not assume that windrvr.sys is loaded and the two files open a communication path between them only to perform short operations, and then close it. This allows eliminating the dependency between the files and results in an improved stability and robustness.
- Fixed the method wdpnp.sys retrieves the bus number of PCI devices. It now retrieves the bus number by directly inquiring the PCI devices, instead of inquiring the Windows operating system, since the operating system always returns 0.
- Fixed IDE to invoke combo box behavior on Windows platforms. The bug caused the default IDE to invoke to be "none". Now IDE to invoke is with accordance to the IDE chosen by the user to generate project makefiles for; the default IDE to invoke is MS Visual C++ 6.0.
USB
- The "send to pipe" operation in DriverWizard was fixed to allow input of long data strings (i.e., more than 1024 chars). The bug caused DriverWizard to issue application error when long data strings were sent.
- Timeout expiration was fixed to avoid BSOD if the USB device is no longer connected.
- WinDriver now uses the operating system's DeviceAddress as a USB uniqueId instead of obtaining the Pointer to Device Object (PDO) from the operating system. Now WinDriver obtains the PDO only for the purpose of communicating with the USB device at the WD_GetConfiguration() and WD_DeviceRegister() stages. The reason is that obtaining the PDO is an intrusive operation, which could interfere with the operation of other devices drivers.
- For Isochronous data transfers, now WinDriver sends the last packet in a separate transaction, instead of the same transaction. The bug caused, in certain circumstances, the operating system USBD to send the last packet twice.

KernelDriver
- DriverWizard was fixed to allow the Debug Monitor GUI to run under Linux.
- Fixed DriverWizard so that it will generate code with an IOCTL to perform WD_License().

Version 5.0.3 (Release Date: September 12, 2001)

New Features

WinDriver and KernelDriver support Windows XP(RC1).
WinDriver supports Windows CE 3.0.

Minor: The evaluation version time limitation, requiring reboot to continue working under Linux, Solaris, VxWorks and Windows CE, was extended to 1 hour instead of 30 minutes.
Minor: The Unique ID of USB devices is now a pointer to a device object (as received from Windows 98/2000/XP(RC1)).
Minor: New design of Quick Start Info window in DriverWizard.

Fixes

General
- (Since version 5.0.0). Level sensitive Interrupt acknowledgment via DriverWizard. Previously, trying to listen to level sensitive interrupts might have caused hangs.
- PLX9030 library — modified the interrupt acknowledge register (INTSCR). Previously this register was accessed as a 32bit register, instead of a 16bit.
Windows 2000
- Interrupt handling on dual CPU. WinDriver now implements a PnP WDM function to retrieve interrupt values.
- Removed the pop up message "Unsafe removal of device" that popped up on device removal.
Linux and Solaris
- "Memory leak" in pthreads usage. Previously, opened threads were not closed properly. May have prevented opening new threads.
Linux
- (Since version 5.0.0). Modified the Kernel PlugIn function, funcIntAtDpc(), to be executed in "bottom half" instead of "top half".
VxWorks
- Print messages from threads, created by InterruptThreadEnable(), now appear a in the calling shell, instead of the device's terminal.
- WD_Sleep() with SLEEP_NON_BUSY option did not work for a time shorter than 1 second.

Corrected the interrupt count value returned by WD_IntWait().

Version 3.0.2 (Release Date: April 24, 1998)

Minor improvements in DriverWizard.
Supports Windows NT checked build.

Version 3.0.1 (Release Date: October 11, 1997)

Minor bug fixes.

Version 3.0.0 (Release Date: September 28, 1997)

Added DriverWizard to package.
DriverWizard enables the programmer to 'talk' and 'listen' to his card via a windows user-interface.
DriverWizard then creates the source code for the driver.
DMA option DMA_LARGE_BUFFER added for locking regions larger than 1MB.
Removed limitation of 20 concurrent DMA buffers in use.

Version 2.1.2 (Release Date: March 21, 1997)

For memory mapped cards: you can now directly access the memory region, without calling WD_Transfer(). The pointer to the memory region is returned in dwUserDirectAddr returned by WD_CardRegister().
DMA transfers: DMA contiguous buffer allocation by WinDriver is available by setting dwOptions = DMA_KERNEL_BUFFER_ALLOC, when calling WD_DMALock(). the linear address of the buffer allocated will be returned in pUserAddr, and the physical address in Page[0]. the buffer is available until calling WD_DMAUnlock().

Version 2.1.1 (Release Date: March 11, 1997)

For PCI cards: Structure used for calls to WD_PciScanCards() was changed. Use pciScan.searchId.dwVendorId and pciScan.searchId.VendorId and the same for dwDeviceId.

Version 2.1.0 (Release Date: February 20, 1997)

For memory mapped cards, changed item dwUserAddr to dwTransAddr.
Use dwTransAddr when calling WD_Transfer().
Added dwUserDirectAddr for direct memory transfers without calling WD_Transfer().
dwUserDirectAddr NOT YET IMPLEMENTED.
