Based on the shipped Windows Qualcomm drivers I have here, for F601 interface 1 is bound by the qcmdm driver, interface 5 is bound by a QMI rmnet, and interfaces 0, 2 and 3 are bound by qcser. That leaves interface 4 for adb. For F622, 0 and 1 are RNDIS, 3 is the qcmdm interface, 2, 4 and 5 are serial, and 6 is adb. I'm not sure what qcmdm does. What format would you like this info in? > The generic Qualcomm driver for 05c6:f601 (which is used by at least one > other brand/reseller) specifies that interface#1 is for USB Modem (ppp > dial-up). Do you have a pointer to that driver? That seems consistent with the Windows drivers, but I have no experience with that. > I assume that you posses this dongle since you add support for it so you can > easily verify that function which I assume has not been disabled in your > version. Yup, I can check that once I know what it's supposed to be speaking :)
