Attached USB devices fail to initialize/work for kernel version 3.5-rc1 and later (up through 3.5-rc4). From what I can tell from the dmesg output (attached), there used to be an "input" or "generic-usb" message that appeared for each device following detection -- showing the sysfs path to the device. For the dmesg output excerpted below, I've left out the USB hub detection/initialization messages. The system *does* have a USB 3.0 hub with nothing currently attached to it, just in case the presence of 3.0 hardware is an issue. The relevant 3.4 boot time messages look like this: (...) usb 1-1.1: new low-speed USB device number 3 using ehci_hcd usb 1-1.1: New USB device found, idVendor=413c, idProduct=2107 usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-1.1: Product: Dell USB Entry Keyboard usb 1-1.1: Manufacturer: DELL input: DELL Dell USB Entry Keyboard as /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.1/1-1.1:1.0/input/input3 generic-usb 0003:413C:2107.0001: input,hidraw0: USB HID v1.10 Keyboard [DELL Dell USB Entry Keyboard] on usb-0000:00:1a.0-1.1/input0 usb 1-1.2: new low-speed USB device number 4 using ehci_hcd usb 1-1.2: New USB device found, idVendor=045e, idProduct=0039 usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-1.2: Product: Microsoft IntelliMouse Optical usb 1-1.2: Manufacturer: Microsoft input: Microsoft Microsoft IntelliMouse Optical as /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.2/1-1.2:1.0/input/input4 generic-usb 0003:045E:0039.0002: input,hidraw1: USB HID v1.00 Mouse [Microsoft Microsoft IntelliMouse Optical] on usb-0000:00:1a.0-1.2/input0 uhci_hcd: USB Universal Host Controller Interface driver usb 1-1.6: new low-speed USB device number 5 using ehci_hcd usb 1-1.6: New USB device found, idVendor=051d, idProduct=0002 usb 1-1.6: New USB device strings: Mfr=3, Product=1, SerialNumber=2 usb 1-1.6: Product: Back-UPS NS 1250 FW:7.g1 .D USB FW:g1 usb 1-1.6: Manufacturer: American Power Conversion usb 1-1.6: SerialNumber: JB0643005571 generic-usb 0003:051D:0002.0003: hiddev0,hidraw2: USB HID v1.10 Device [American Power Conversion Back-UPS NS 1250 FW:7.g1 .D USB FW:g1 ] on usb-0000:00:1a.0-1.6/input0 The 3.5-rc4 messages look like this: (...) usb 1-1.1: new low-speed USB device number 3 using ehci_hcd usb 1-1.1: New USB device found, idVendor=413c, idProduct=2107 usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-1.1: Product: Dell USB Entry Keyboard usb 1-1.1: Manufacturer: DELL usb 1-1.2: new low-speed USB device number 4 using ehci_hcd usb 1-1.2: New USB device found, idVendor=045e, idProduct=0039 usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-1.2: Product: Microsoft IntelliMouse Optical usb 1-1.2: Manufacturer: Microsoft uhci_hcd: USB Universal Host Controller Interface driver usb 1-1.6: new low-speed USB device number 5 using ehci_hcd usb 1-1.6: New USB device found, idVendor=051d, idProduct=0002 usb 1-1.6: New USB device strings: Mfr=3, Product=1, SerialNumber=2 usb 1-1.6: Product: Back-UPS NS 1250 FW:7.g1 .D USB FW:g1 usb 1-1.6: Manufacturer: American Power Conversion usb 1-1.6: SerialNumber: JB0643005571 Thanks in advance for any assistance in figuring out what's going on here. --Bob -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
