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?

Do you have a pointer to that driver? That seems consistent with the
Windows drivers, but I have no experience with that.

Yup, I can check that once I know what it's supposed to be speaking :)
