[RESOLVED] USB flash drive no longer creates special device file when inserted.

Postby driftwood » 2012/01/26 15:11:39

It used to automatically create /dev/sdb1 when I inserted the memory stick, but no longer. Routine updating and rebooting of the OS has been done since it last worked. I'm on Centos 5.7. hald is running. I have tried 2 sticks, both of which work in other machines, and which have worked in this one in the past. The light comes on on the Sandisk Cruzer stick which I have tried. I have used 2 USB ports on the machine.
Does anyone have any idea what's wrong?

nothing relevant appears in /var/log/messages, or dmesg, though it used to IIRC.

Odd that lsusb shows nothing. Your getinfo.sh output seems truncated, but shows no USB hardware present. Is it perhaps disabled in the BIOS?

I will check the BIOS when I can. ie when users go home. I've noticed that the Sandisk Cruzer's light does 'breathing' (ie slow flashing) when I put it in other Linux machines, but not in this one.

Thanks.

Well, there's nothing relevant in the BIOS, it's very unusual, it's a Dell Poweredge and everything in the BIOS is to do with the RAID controller.
I've worked around the problem by using the USB drive on another machine which has access to the same data.
I think it's probably a hardware failure, the machine is quite old.

Seems likely. Can't mount USB devices if the OS sees no USB hardware. So, do you consider the issue [RESOLVED]?

Yes, it's as well resolved as it's going to be :-)

Less than satisfactory but apparently no better resolution is forthcoming. Marked accordingly.
