** Description changed: Certain USB devices do not work while the ehci_hcd module is loaded. - A solution is to unmodprobe ehci_hcd, which is loaded every time the - computer starts. This is normal and necessary for using usb 2.0 - highspeed. + A solution is to unload the ehci_hcd module, which is loaded every time the computer starts, using the command 'sudo modprobe -r ehci_hcd'. This works fine but unfortunatly ehci-hcd is necessary for using USB 2.0, so you lose USB 2.0 features. + Another solution is to disable USB 2.0 through the BIOS setup. - ProblemType: Bug - Date: Wed Feb 28 19:34:17 2007 - DistroRelease: Ubuntu 7.04 - Uname: Linux schlumpf 2.6.20-9-generic #2 SMP Mon Feb 26 03:01:44 UTC 2007 i686 GNU/Linux + Steps to reproduce: + 1.
