Public bug reported: Hi,
when I try to use my Gembird USB-Keyboard on a machine with a VIA chipset the uhci_hcd module seems to be unable to set up the device correctly. Unloading ehci_hcd or using noapic as suggested in some forums didn't bring any effects. Dmesg | grep usb says: [ 0.692770] usbcore: registered new interface driver usbfs [ 0.693047] usbcore: registered new interface driver hub [ 0.693382] usbcore: registered new device driver usb [ 3.730965] usbcore: registered new interface driver libusual [ 3.731452] usbcore: registered new interface driver usbserial [ 3.731914] usbcore: registered new interface driver usbserial_generic [ 3.731924] usbserial: USB Serial Driver core [ 7.400765] usb usb1: configuration #1 chosen from 1 choice [ 7.401883] usb usb2: configuration #1 chosen from 1 choice [ 7.720138] usb 2-1: new low speed USB device using uhci_hcd and address 2 [ 12.927332] usb 2-1: configuration #1 chosen from 1 choice [ 17.925604] usb 2-1: can't set config #1, error -110 And after plugging out and in again: [ 945.048111] usb 2-1: USB disconnect, address 2 [ 945.784061] usb 2-1: new low speed USB device using uhci_hcd and address 3 [ 960.896061] usb 2-1: device descriptor read/64, error -110 [ 976.112060] usb 2-1: device descriptor read/64, error -110 [ 976.328120] usb 2-1: new low speed USB device using uhci_hcd and address 4 [ 991.440061] usb 2-1: device descriptor read/64, error -110 lspci says: 00:10.0 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 80) 00:10.1 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 80) This happens on all my VIA machines after grub is booting the kernel, on my notebook (using ohci_hcd) the keyboard is working fine. I've tested this issue with all currently supported Ubuntu versions, Jaunty and 2.6.29 vanilla included. Then I booted from an old Ubuntu 5.10 Breezy Badger Live DVD, where it is working fine too. Thanks in advance.
