Resuming our earlier discussion, I got another case of weird USB messages here with kernel 2.6.30-rc5 (sorry, I have not yet had time to use anything newer). My father has a USB (1.1, I would say, which matches what the logs say) stick/pen drive that, when I connect to my ECHI controller on my machine with an ICH5 chipset, I get: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - [ 2285.628018] usb 4-2: new full speed USB device using uhci_hcd and address 2 [ 2285.784924] usb 4-2: New USB device found, idVendor=067b, idProduct=2315 [ 2285.784932] usb 4-2: New USB device strings: Mfr=1, Product=3, SerialNumber=0 [ 2285.784936] usb 4-2: Product: USB Embedded Hub [ 2285.784939] usb 4-2: Manufacturer: Leading Driver Co.,LTD.
