Interesting.
I also see Quectell LTE Modem on USB Bus 003, device 002: ID 2c7c:0125 on my PinePhone.
Problem is: when modem is hardware killed with physical switch flipped "off" and then back "on" - the modem does not re-appear in lsusb output.
At this point running as root
usb_modeswitch -R -v 2c7c -p 0125
gives
It seems that after being killed with hardware kill-switch host has to reset the bus to enable the re-enumeration of the device (source Replicant devs: https://www.mail-archive.com/replicant@o...00700.html)
Is there way to reset USB Bus 003 to force enumeration of attached USB devices?

Code:
Look for default devices ...
No devices in default mode found. Nothing to do. Bye!It seems that after being killed with hardware kill-switch host has to reset the bus to enable the re-enumeration of the device (source Replicant devs: https://www.mail-archive.com/replicant@o...00700.html)
