I have a Problem with my RUT950 which disconnects a few times every hour.
In the Logfiles I found these entries:
usb 1-1: USB disconnect, device number 2

Firmware is the latest: RUT9_R_00.07.02.6, I also have a second RUT950 which shows the same Problem.
I tried Factory Reset, different SIM Cards, Firmware downgrade, Manual APN Entry, removing SIM Pin but the Problem still exists.
I also added a troubleshoot File to this request, thanks for your help and kind Regards.
