Windows 7 - WinUSB and xp3 DTM tests

Asked By Kim Latt

02-Feb-10 02:54 PM

My company and I have developed a usb device, which is suitable for the kind
stuff that can be done using Winusb.sys.

While implementing the code using winusb.sys and installing the drivers on
vista x86 -> Win 7 x64 has been a simple task.
Writing and understanding the requirements to an inf-file suitable for win
xp installs has been pretty complicated, in fact
so complicated, that I am about to give up.

I just followed the numerous examples in win ddk on how the inf file is to
be written.
The first time I realized that something was wrong, was whilst DTM'ing the
driver for whql submission.

My question is: What should be done to the inf-file below, to satisfy xp,
chkinf and WLK?

You cannot make a WinUSB-based INF file that passes chkinf for XP.  To use
WinUSB, you have to needs/include WinUSB.INF, and in XP that is not a
standard INF file.

I believe there is a DTM exception for this.  You should contact WHQL about
it.

This is what I have realized - But there are not any exceptions in the
filters for this.

I have a hack that seems to fix it, but I dare not submit it to whql:

Simply put a "dummy" winusb.inf into the windows\inf directory on the
xp-machine and rerun
the test.

I have read Peter Wielands blog on the subject. An tried doing another
inf-file that navigate "run-time" to another
section of the inf-file for xp and fixes the coInstaller issues with the DDK
samples.
(http://blogs.msdn.com/peterwie/archive/2007/01/10/fixing-the-umdf-usb-samples-to-install-both-on-xp-vista.aspx)

But the check that chkinf does is static or rather it tries all

Anybody else in here who has a solution? Or nows howto persuade whql to
ignore the chkinf problem?!

I am happy to inform the group, that the exception is back in the DTM
filters. Now WLK 1.5 allows winusb to be used in xp drivers
