Thierry, >From looking at that output it appears you don't have the EHCI driver loaded (USB 2.0 support), this driver is required for the CinergyT2 to operate. Either your laptop is USB 1.0/1.1 only (in which case you'll need a USB 2.0 hardware upgrade) or you just need to load the EHCI driver before the CinergyT2 driver. Steve
