usb stopped working

I've got a usb disk. After plugging it into an untrusted device, it no longer can be read(it worked pretty well before that).
At first I thought that it was just a compatibility problem, but then I found that it got unexpectedly broken on my own computer.

The usb device is detected:

 Elements SE 25FE:

              Product ID: 0x25fe
              Vendor ID: 0x1058  (Western Digital Technologies, Inc.)
              Version: 10.21
              Serial Number: 5758543145323830434C4D30
              Speed: Up to 5 Gb/sec
              Manufacturer: Western Digital
              Location ID: 0x00230000 / 2
              Current Available (mA): 900
              Current Required (mA): 896
              Extra Operating Current (mA): 0

But the system cannot find the usb disk(not just file system, tried fdisk -l). This is the problem. If it were a more high-level program, like the data on the disk got overwritten, I should have fixed that by checking the disk with some command tools.

Re: usb stopped working

Most of the time this is an issue if you've updated your kernel but haven't rebooted yet so the currently running kernel is not able to load the necessary usb-storage module from disk.

So if

pacman -Q linux #Or whatever kernel pkg you are running
uname -a

differ in versions, you should reboot your system before surmising that your USB got broken.

Unfortunately, not this time. I've tried multiple devices.

Re: usb stopped working

Then you need to post actually actable information, what do you see in your dmesg when you plug in a USB device?
