Here is the list of what is going on with the usb core when I change the config from 1 to 2. I started at poweron and captured the different states. You will see in Step 5 that there is a uhci failure. Again, this is 2.6.9. I will try moving to a newer kernel now. -Mike ========================= CUT HERE ============================ ============================================== Step 1: Just after system boots ============================================== usbcore: registered new driver usbfs usbcore: registered new driver hub USB Universal Host Controller Interface driver v2.2 uhci_hcd 0000:00:1d.0: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #1 uhci_hcd 0000:00:1d.0: new USB bus registered, assigned bus number 1 usb usb1: new device strings: Mfr=3, Product=2, SerialNumber=1 usb usb1: default language 0x0409 usb usb1: Product: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #1 usb usb1: Manufacturer: Linux 2.6.9-sti1 uhci_hcd usb usb1: SerialNumber: 0000:00:1d.0 usb usb1: hotplug usb usb1: adding 1-0:1.0 (config #1, interface 0) usb 1-0:1.0: hotplug hub 1-0:1.0: usb_probe_interface hub 1-0:1.0: usb_probe_interface -
