Hi,
I have visited various blogs and forums and set out to perform usb mode switching in FEDORA20.
Kindly have a look into various settings and logs in my machine.
Mode switching fails and I'm getting "No driver found. Either detached before or never attached" error message.
Meanwhile there is a line printed in console " No devices in target mode or class found" while executing usb_modeswitch command.
The device is shown to be detected as usb-storage in dmesg.

Any directions to get this working is greatly appreciated.
