Hi,
I need to write a driver which supports virtual COM port emulation over
USB (for win2k/XP). Can I make use of usbser.sys provided by Microsoft. Where
can i get a complete description of usbser.sys. Does it provide Bulk mode
transfer.
How Can i add an upper/lower filter to usbser.sys.

Thanks in advance.
