Hi
I tried to configure my wireless adapter to auto unmount and switch but not worked.
Before (manual) switch:
Code:
lsusb
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 002: ID 03f0:134a Hewlett-Packard Optical Mouse
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 006: ID 0bda:1a2b Realtek Semiconductor Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

After (manual) switch:
Code:
~$ lsusb
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 002: ID 03f0:134a Hewlett-Packard Optical Mouse
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 009: ID 2001:331d D-Link Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

I followed this :
Code:
https://askubuntu.com/questions/43805/help-with-implementing-usb-modeswitch


I made a file with name : 0bda:1a2b
The content of the file :
Code:
# D-Link DWA-171

TargetVendor=   0x2001
TargetProduct=  0x331d


I put it into dir usr/share/usb_modeswitch and tinto dir etc/usb_modeswitch.d too
After reboot the dongle not mounts (at least) but stay on disk mode. When I run this command :
Code:
$ sudo usb_modeswitch -c /etc/usb_modeswitch.conf
Look for target devices ...
 No devices in target mode or class found
Look for default devices ...
 Found devices in default mode (1)
Access device 010 on bus 001
Get the current device configuration ...
Current configuration number is 1
Use interface number 0
 with class 8
Warning: no switching method given. See documentation
-> Run lsusb to note any changes. Bye!


If I use :
Code:
$ sudo usb_modeswitch -KW -v 0bda -p 1a2b

it switched :
Code:
Take all parameters from the command line


 * usb_modeswitch: handle USB devices with multiple modes
 * Version 2.5.2 (C) Josua Dietze 2017
 * Based on libusb1/libusbx

 ! PLEASE REPORT NEW CONFIGURATIONS !

DefaultVendor=  0x0bda
DefaultProduct= 0x1a2b

StandardEject=1

The log says "Warning: no switching method given."

It worked when you used the -K switch on the cmdline but your device config file
has only the target id and is missing a switch method.
-K on the cmdline is equivalent to StandardEject=1 in a device config file so that is what you have to add.
You'll also have to create an entry for 0bda:1a2b in the 40-usb_modeswitch.rules file so that usb_modeswitch is invoked automatically as soon as the dongle appears on the usb bus.

I followed the instructions , completed the files and it works properly. The problem is solved.
Thanks for your support.
