Hi Thomas,

for the EM7565 you should have used AT!USBCOMP=1,3,100D to switch it to MBIM
mode and AT!USBCOMP=1,3,10D to switch it back to QMI. Please see this thread
https://forum.sierrawireless.com/t/em7565-wrong-usbcomp-command-sent-did-i-brick-it/13726
on how to get back the standard USB interface layout.

Reinhard
