Usb driver installation

NTDEV
1

Hi all,

I am facing a strange condition while attempting to pre-install on Win2K my
new usb driver with fastinst.exe.
At the end of the installation process my driver is unexpectely loaded and
started.
StartDevice procedure of course fails with code 0xC0000010 when requesting
USB_DEVICE_SESCRIPTOR_TYPE
I presume because there is no real device attached.
As result I have in device manager an instance of my device with a great
yellow !
When I manually uninstall this instance everything works fine, driver is
loaded as soon any device is attached.
The problem seems to be related to UpdateDriverForPlugAndPlayDevices(), I
have the error
with both fastinst.exe and a custom setup program which uses
UpdateDriverForPlugAndPlayDevices().
Using SetupCopyOEMInf() everything works fine, but I would like to
understand why I am loaded without any
real device attached.

Any suggestion will be very appreciated
in the meanwhile an merry Christmas and happy new year to everybody in the
list,

PaoloC

FASTINST creates a root-enumerated device node, which is where the
yellow-bang instance comes from. You have the source code, so you can
make your own version of the utility that will just identify the device
ID by parsing the INF and then call UpdateDriversEtc.

I am still a bit confused.
You suggest to:

A) SetupDiCallClassInstaller(DIF_REGISTERDEVICE) +
UpdateDriverForPlugAndPlayDevices + SetupDiCallClassInstaller(DIF_REMOVE)

OR

B) Just invoke: UpdateDriverForPlugAndPlayDevices

Thanks a lot Walter,

Just B.

Look, FASTINST does three things: (1) parse the INF file to select a
device identifier, (2) create a root enumerated device with that
identifier, and (3) UpdateDriverEtc. You want (1) and (3), but not (2).

All FASTINST does that DEVCON doesn’t is to select a device id by
default. I designed it that way because most INF files used to test
legacy drivers have just one device id.
