Comment 14 for bug 1716301

I just fell a little strange that is , why some info log in mt7801u is not printed,
e.g: in 09-26.2.txt, no any log about mt7601u. however, in mt7801u code, it printed those info....

[ 127.095245] mt7601u 1-1.4:1.0: ASIC revision: 76010001 MAC revision: 76010500
[ 127.146876] mt7601u 1-1.4:1.0: Firmware Version: 0.1.00 Build: 7640 Build time: 201302052146____

and I sometimes still can see on kernel 4.13 or 4.4.0-91
  Vendor request failed with -110.

what's the differences between replying on system to automatically switch mode and I manually eject the disk , or if I run command
sudo usb_modeswitch -v 148f -p 2878 -V 148f -P 7601 -K

Thanks !
