Hi,

Possibly not a winusb specific question, but it is possible to have 1
single winusb based device driver for a composite usb device (2 interfaces)?
Can this be achieved via 1 single INF file, or do I need 2 seperate (albeit
very similar) ones?

I've been looking at http://www.cygnal.org/ubb/Forum9/HTML/001050.html which
seems 2 suggest I'll need 2, which I'd like to avoid?

Also is it possible to have my composite usb device appear as a single
entity within the device manager

as long as you want the 2 interfaces to be isntalled in the same device
class, yes you can use one INF. you just need to HW ID matches in the INF

Sure. If your INF file matches the composite device VID and PID, then
you'll be loaded for the composite. If you DON'T match the composite
device, then usbccgp.sys will expose the individual interfaces with the
MI_00, MI_01, MI_02 etc. suffixes.
