In version 6.2.0 of WinDriver, the PCI configuration space read/write method on
Windows was upgraded to a more advanced method. On rare occasions, this method
fails to identify some PCI devices. To resolve this problem, beginning with
version 10.3.1 of WinDriver you can revert to the legacy PCI configuration
space read/write method by doing the following:
- Set the
PciCfgRwCompat registry key flag in the WinDriver
driver INF file — default: windrvr<version>.inf (e.g.,
windrvr1200.inf) / windrvr6.inf in earlier
versions — to 1:
HKR, Parameters, PciCfgRwCompat,
0x00010001,
1
Beginning with version 11.1.0 of WinDriver, the driver INF file
contains a similar line, which sets the PciCfgRwCompat
flag to 0 (default), so you only need to modify the value of the flag
in the existing line to 1.
- Open a command-line prompt and reinstall the driver by running the
following commands from the WinDriver\util\wdreg directory
(where "WinDriver" is the path to your WinDriver installation
directory):
$ wdreg -inf <path to your device INF file> uninstall
$ wdreg -inf <path to the driver INF file> uninstall
$ wdreg -inf <path to the driver INF file> install
$ wdreg -inf <path to your device INF file> install
