My company has a device that uses usbser.sys in WindowsXP/2000/Vista to act
as a CDC Vcom port. It works fine in those OS versions. The problem I am
having is that when I attempt to use the same .inf file in Win98 I see my
device as installed with no problems in device manager but the device never
seems to be issued a port number. I have not been able to find any example
inf files for USB CDC vcom that use Win98. I have read some documentation on
version with XP/2000 that claim that you can use CDC on Win98 by modifying
the .inf file. Has anyone used or seen a CDC .inf file for Windows98 that
correctly installs a CDC VCOM device and issues it a port number correctly in
device manager?
