Couldn't they at least use a unique device ID for things with completely different layouts, when all interfaces are vendor specific? Too much to ask, obviously. > + case 4: > + /* Don't claim the QMI/net interface */ > + altsetting = -1; > + break; > + } I guess this means that we need to add an interface count quirk to the qmi_wwan driver as well? I assume there are devices out there with the same device ID, the same ff/ff/ff interface descriptors, but with QMI/net on interface #0. Could you post the complete lsusb output? I believe it is important to document that for the future in case we have to redo this later. Which is likely given the experiences so far - there might be other devices using the same ID with yet another layout.
