What is the output of "lsusb -vvv" for your device?
I am asking because you have to use IAD for USB composite device
with a CDC-ACM as one of the interface. If you are not using IAD, the
whole thing would not work under Windows. You also need to use
XP SP3 or Vista/Win7.
Sorry for the confusion. We are not using CDC ACM, but we are using
serial driver which mimics the CDC ACM class with only one interface
supporting three endpoints. I think we need the IAD, if we are
supporting more than one interface in the driver, Right?
At least WIndows XP is asking to manually install Host drivers, whereas
Windows 7 is automatically installing the drivers on it own. Any pointers
would help?
Even without an inf file?
Yes, without any .inf file in the case of Windows 7 and it asks for an .inf
file in the case of windows XP.
That is kind of strange. I tried to use a real USB RNDIS device (Windows
CE based) under Windows 7 and it is asking for an inf file. Are you using
a know VID/PID for your device that Windows happen to know about
with the default built-in RNDIS driver?
Our VID : 0x5c6 and PID is 9024. Not sure, if this is a known VID/PID
for the default built-in RNDIS drivers.
