I tried kernel 4.13. however, no much diff with kernel 4.4.0-91.
I must mention that in both kernel, no ALAWAYS the adapter is automatically
recoginized as 148f:7601, sometimes, it still mounted as 148f:2878, sometimes,
it's 7601. ( I found the pattern is: unplug the adapter, wait a relative long
time, e.g: 1 or 2 minutes, plug the adapter, then it's 7601. if immediately
plug in the adapter, say just wait 10 seconds, mostly, it's mounted as usb
stroage disk and will not change to 7601).
I can use following command to switch mode, with errors, but mode
changed to 7601.
chenzero@chenzero:/usr/share/usb_modeswitch$ sudo usb_modeswitch -v 148f -p
2878 -V 148f -P 7601 -K
