Every so often (a few times per hour) my mouse will momentarily "freeze". The following messages appear in syslog, indicating that the mouse has disconnected and then immediately reconnected: Sep 20 19:45:28 pingu kernel: usb 2-2: USB disconnect, device number 3 Sep 20 19:45:28 pingu kernel: usb 2-2: new full-speed USB device number 4 using uhci_hcd Sep 20 19:45:28 pingu kernel: usb 2-2: New USB device found, idVendor=046d, idProduct=c245 Sep 20 19:45:28 pingu kernel: usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Sep 20 19:45:28 pingu kernel: usb 2-2: Product: Gaming Mouse G400 Sep 20 19:45:28 pingu kernel: usb 2-2: Manufacturer: Logitech Sep 20 19:45:28 pingu kernel: input: Logitech Gaming Mouse G400 as /devices/pci0000:00/0000:00:1c.4/0000:03:00.0/0000:04:00.0/usb2/2-2/2-2:1.0/input/input35 Sep 20 19:45:28 pingu kernel: hid-generic 0003:046D:C245.0020: input,hidraw0: USB HID v1.10 Mouse [Logitech Gaming Mouse G400] on usb-0000:04:00.0-2/input0 Sep 20 19:45:28 pingu kernel: hid-generic 0003:046D:C245.0021: hiddev0,hidraw1: USB HID v1.10 Device [Logitech Gaming Mouse G400] on usb-0000:04:00.0-2/input1 Sep 20 19:46:03 pingu mtp-probe: checking bus 2, device 4: "/sys/devices/pci0000:00/0000:00:1c.4/0000:03:00.0/0000:04:00.0/usb2/2-2" Sep 20 19:46:03 pingu mtp-probe: bus: 2, device: 4 was not an MTP device The problem seems to have started after a recent kernel update. /proc/version: Linux version 3.12.25-desktop-3.mga4 (iurt@ecosse.mageia.org) (gcc version 4.8.2 (GCC) ) #1 SMP Sun Jul 27 23:33:54 UTC 2014
Problem turned out to be a fault in the mouse: fortunately it was still in warrenty (3 years warrenty) and Logitech replaced it with a new G402.
