It does seem Toby has the exact same problem I am having. The only solution I found really worked for me was to revert to an older version of Ubuntu that uses the 9.28-9 kernel (Ubuntu 9.04 Alpha 6) instead of the 9.28-11 kernel. The off/on trick or adding a USB flash drive is not really a solution. This problem exists under both 32 and 64 bit versions and different desktops, so I suspect it is an USB related kernel bug Not local to Ubuntu or Kubuntu. Before kernel 9.28-11 there was no problem. It all started for me with the kernel update to 9.28-11.
