    usb not detected?

    Hello, One of my USB drives recently stopped working in ubuntu. It was definitely working before my fresh install of 11.04 about a month ago, but I can't be sure if I used the USB since then.

    The problem: I have 2 USB slots, and one of them automounts as expected, while the other one does not work. On the nonworking slot, I plug in a USB storage device and the device appears to be busy (light on, device says it's charging, etc), but ubuntu cannot `see' it.

    Steps so far:

    1. I wanted to mount it manually via the command line. However, I cannot find any entry for the usb in /dev/ (I looked for entries called sdb* and usb).

    2. I tried to check fdisk, but it is not there, either:
    Code:
    ~$ sudo fdisk -l
    
    Disk /dev/sda: 160.0 GB, 160041885696 bytes
    255 heads, 63 sectors/track, 19457 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disk identifier: 0xf761d1b8
    
       Device Boot      Start         End      Blocks   Id  System
    /dev/sda1   *           1        9014    72404923+   7  HPFS/NTFS
    /dev/sda2            9015       10838    14650369    5  Extended
    /dev/sda3           10839       19326    68179860   83  Linux
    /dev/sda4           19327       19457     1052257+  82  Linux swap / Solaris
    /dev/sda5            9015       10586    12619776   83  Linux
    /dev/sda6           10586       10838     2029568   82  Linux swap / Solaris
    3. I checked lshw to see if the hardware is broken, assuming that if it is broken, an entry for usb will not appear on the list. (is this assumption correct?):

    ~$ sudo lshw -c bus

    Any advice out there?

    Re: usb not detected?

    So I'm pretty sure now that my computer was broken. It may have been an issue with the motherboard because several inputs broke at around the same time including the CD-ROM and power plug, and none of them worked in windows or when booting from a live cd.
