My Mediatek usb flash drive is not get detected.

The o/p of lsusb

falguni@falguni-M61PME-S2P:~$ lsusb
Bus 002 Device 002: ID 0e8d:0003 MediaTek Inc.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

and the o/p of usb-devices

But in 12.04, the o/p of usb-devices was:

It was working fine in 12.04. Now after upgrading to 12.10 the problem started.

Where is the problem and how to solve it?

I had the same issue. (USB was getting detected on windows) Although USB drive was not displayed in the file explorer, it was still being detected on lsusb. steps below might work if you're positive on the lsusb part.

  • Take a back up of all the files on windows
  • Plug the USB back on ubuntu
  • Format using Disk Utility (Disk on 13.04)
  • Make sure you create a new partition

Hopefully, your USB drive will now be working fine.
