USB2 not working

[pompeyrodney]

Hi I am running Karmic on an old IBM T23 laptop. It is fitted with a USB2 card but this has stopped working and I am none too sure where to start looking to find the fault. If I plug in a good flash drive it does seem to be recognised and does not show up when I run "lsusb". Thanks in advance.

did you try with 'disk utility' (system > administration > disk utility)? if you don't have it, install it thru 'Ubuntu software center'. That helps me - my usb was corrupted so I formatted it with du
