      How to detect usb devices using Ubuntu 8.04 LiveCD?

      I'm trying to detect an external HDD drive, but I don't know how. My PC has a total of 6 USB ports, they're all being used, and the Computer File Browser lists only 4 USB ports and I can't open them. The ports could be detected in Windows Vista, except I've not tried the new HDD enclosure, but the PC's HDD crashed.

      I've ran the command:
      Code:
      dmesg
      without the usb enclosure:

      Code:

      I can't read this, but used quickdiff.com to compare the difference. Each Time that I run the commands, I get different results such as these differences:

      If not already installed, install gparted (partition editor)
      Then, fire up gparted (it's in system > admin)

      There's a drop down box in the top right corner
      Does the drive show up?

      GParted doesn't show anything. What dropdown box in the top right corner, please show an image of what you mean (use Google Images).

      What kind of external HDD are you trying to connect? Does it use encryption software? I have a eagate drive that uses encryption and you have to use Windows software to access the data. The only way to get it to work with Linux is unlock the device in a Virtual Windows Machine and then unmount it from the Virtual PC

      If you can't see it via Computer, It may be connected but not mounted.
      Furthermore it could be unformatted or even lack an fdisk table. The only
      OS I know with the command for writing an fdisk table is Solaris but If
      you want check out this tutorial I wrote on setting up an external drive:
      Format Mass-Storage Device For Cross-platform Capabilites - Linux Tutorials | Dream.In.Code

      Hope this helps,

      It's just that none of mt USB devices are being detected in either Computer or GParted. I know that the USB ports work because both my keyboard & mouse are USB devices, not PS/2 as most are.

      If you go to System>Administration>Disk Utility (I use 10.04 so hopefully it is in 8.04) the drive should show up even if it it unmounted or unformatted. But going back to your original post where it says "usb 2-5: USB disconnect" it sounds like the last 4 USB ports have been disabled. I've honestly never used dmesg though so I can't say for sure. Try disconnecting your keyboard and putting the HDD in that port and see if it shows up.

      Some of your usb ports could be bad... There isn't a whole lot of information so I'm just speculating

      Yea shadow, that's why I asked him to unplug his keyboard and see if it would work on a known good USB port.
      Is there a Windows system you can use to see if the HDD shows up there?
