Thanks the suggestion of Hardy. I could not live without USB so I performed the following
1. Disabled USB 2 in the BIOS set up 2. As Ubuntu no-longer sees any usb2 devices, all usb keys and external drives worked correctly but at usb1.1 speeds. 3. I installed a USB2.0 PCI Card as I have a 500Gb hard disk and accessing at 1.1 speeds didn't cut it. This meant I had 6 ports running at USB2 and the 4 ports on my mobo running at 1.1. 4. Some weeks later when Leann replied I tried the alpha mentioned after re-enabling usb2 in the bios. All USB ports operated at full speed. 5. Coincidently I gave gutsy another go and it appears that all ports are now working again so as to the problem I really don't know what went wrong or why its fixed itself Kris -- USB Mass Storage Devices not mounting, device not accepting address, error -32 https://bugs.launchpad.net/bugs/195762 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
