bokkie:
The router OS does not give more specific information, but I put it into a Linux box and got the full descriptor listed in the attachment below. But note that lsusb
So it looks like only the product ID is incorrect. Before I messed up the product ID, the router OS listed 5 channels for this device, and the descriptor listing shows there are 5 interfaces, even though none is accessible. If everything else is correct for the MC7710 in the mode that I want to use, then it should be possible to rescue it if I can find a suitable driver and a way directly to change the product ID back to 68a3 without using AT commands.
Any clue how to do this would be appreciated.
I cannot download the attachment for some reason (“has been deleted”?). But if there are 5 interfaces then it is very likely that one or more are connected to the AT interpreter and will allow you to reset the ID. In Linux, try something like
modprobe option
echo 1199 68b1 >/sys/bus/usb-serial/drivers/option1/new_idThis should give you a number of ttyUSBx devices. Try them one by one and see if they respond to AT commands.
