Recently I buy a new USB wireless adapter. This device can work in windows, but it can not work on Ubuntu 16.04.
I read some article in this website, so I do the following steps.
barry@barry-R458:/home/netxianren$ usb_modeswitch -e
* usb_modeswitch: handle USB devices with multiple modes
* Version 2.2.5 (C) Josua Dietze 2015
* Based on libusb1/libusbx
! PLEASE REPORT NEW CONFIGURATIONS !
barry@barry-R458:/home/netxianren$ uname -a

The device 148f:2878 Ralink Technology, Corp. is my USB wireless adapter.
Then I execute the following command:
barry@barry-R458:/home/netxianren$ sudo usb_modeswitch -KW -v 148f -p 2878
Take all parameters from the command line

I'm very happy. Because the divice switched to 148f:7601 Ralink Technology, Corp. MT7601U Wireless Adapter.
But the device still can not work. So I execute the following cmmand:
barry@barry-R458:/home/netxianren$ sudo usb_modeswitch -KW -v 148f -p 2878 -s 3 -V 148f -P 7601
