As I mentioned before, WHQL submission is not necessary for
drivers using usbser.sys. It will work under 32bit/64bit Windows.
The warning just scares some innocent customers.

You do not need the catalog file here. Those vendors who likes to get
the WHQL can pay the money to get it (for their particular VID/PID).

For drivers like libusb-win32 (libusb0.sys), it is a big problem since
you can not load it under 64bit Vista/Win7. libusb-win32 is quite
nice project to port Linux libusb based application to Windows.
So we in the libusb-win32 project plan to get the money through
donation to buy the digital certificate so that it can work under
64bit Vista/Win7 and users can load it (with the red warning
since the driver package are not signed with the digital
certificate, inf file is part of the driver package). Corporate
users of libusb-win32 (eg: Atmel) can choose to go for WHQL so that
their users will not see the red warning.

usbser.sys is already signed by Microsoft, so you will not
face such issue. Same thing for the drivers of USB RNDIS.
