Hi Mandeep, >>>>>> I'm not sure if there's one available for the n810 tablet. I searched the apt repos and it didn't show up there... <<<<<< Could you just try USB snoopy on XP ? I've used it many times to get my out of jail card. At least you would see what the descriptors seem to hold in your CDC device. I don't know about the latest rev on Snoopy, but one pain is that it doesn't log/display string descriptors. Note that the usbser.sys is pretty rooted on XP, which you probably know. I once spent 2 days trying to get handshaking to work under ACM - apparently there's bugs galore in usbser.sys. But it would allow you to perhaps get some more insight into the eth properties side of the CDC device. And indeed, if the host issues SET_CONFIGURATION, then your enum must have been OK. My next guess or object of scrutiny then would be whether the parameters of SET_CONFIGURATION are in place, and suitable for the Ethernet on the device's side. This is all conjecture, naturally. Sounds like you got a good grip on things there anyway. Good luck !
