Hello all, I sent the above email a few days ago but I don't think it went through on account of a large additional attachment. That attachment (372K in size) contains a full USB capture trace of the modem being successfully driven from Windows (everything from Hotplug to connection), while running in a VM (captured using Wireshark). It is clear from the trace that Windows uses PPP on it. The device is 19d2:1517 initially and usb_modeswitch transforms it to a device with ID 19d2:1519. To whom do I send this USB capture trace, which should allow development of complete support of this device? I reiterate that Dmitry's patch works to establish a full and usable internet connection. I am happy to supply any further information, or to help in analysis or debugging, even at fairly low levels. Many thanks! -- Brian Gitonga Marete Toshnix Systems - http://toshnix.com
