Hi All,

We use a CDC device implementation( modem), and is making use of
usbser.sys as the communication driver. As per our requirement we need
to emulate multiple virtual COM ports over the usb. (usbser emulates
only 1 com port). Is there a way,by which I could emulate multiple COM
ports,using USBSER.ie can I add an upper filter to usbser,wherein I
create multiple com ports.Does usbser supports this.

Plz help ..................
Thanks in Advance,
Teena.
