[SOLVED] USB devices not mounting

I was downloading stuff into my usb drive with KTorrent. I came back later to check up on it and KTorrent said there was an error with the drive (don't remember what exactly).

Next, I updated my system and restarted (hoping this would fix the problem).

It was not fixed so I proceeded to investigate the issue further:
- lsblk does not show the device at all (sdb)
- dmseg does not show the device
- if the usb drive is replaced by my android phone, dmesg shows the output below indicating that it is recognized. However, I still can't do anything with the drive and it does not appear in lsblk.

Is it broke perhaps? Can you see the drive when plugged in on another computer?

I possess a device, in my pocket, that is capable of accessing the entirety of information known to man.
I use it to look at funny pictures of cats and to argue with strangers.

Re: [SOLVED] USB devices not mounting

When I plug it into a Windows computer, it is also not recognized and nothing happens. The android works and I am able to access files, though.
On arch, the android does not mount (not in lsblk), but now I tried a flash drive and it worked.

Re: [SOLVED] USB devices not mounting

So you just have a broken flash drive is all.  You Android device is not a disk and should not (normally) be recognized as one.  If you want to transfer data to/from an android device, that is a separate question which is well covered in the wiki.

I was able previously to access my android. First it would show up in my plasma desktop notification. Then I would click mount and I can see it in dolphin. Now, i am not able to do that.

Re: [SOLVED] USB devices not mounting

See Trilby's post. The Android devices do not automatically mount as drives, you have to make them do that. Read the appropriate section of the Wiki: https://wiki.archlinux.org/index.php/An … oid_device

Re: [SOLVED] USB devices not mounting

Update:
- My external hdd is faulty since it makes a noise when plugged in. (I hope this was not caused by arch.)
- I think my android problem had nothing to do with the hdd. It was solved by installing  kio-mtp.
