The mouse is not recognized on boot and i have to unplug replug the receiver multiple times in some cases. I tried it on an older kernel (2.6 series) that i had available and it worked just fine. This problem was present in 3.3.8 and in the 3.4.2 kernel. The problem was also reported in Ubuntu: https://bugs.launchpad.net/ubuntu/+bug/958174 My dmesg read something like after the problem occurred: dmesg | grep -i logitech [ 4.146194] logitech-djreceiver 0003:046D:C52B.0005: hiddev0,hidraw2: USB HID v1.11 Device [Logitech USB Receiver] on usb-0000:05:00.0-1/input2 [ 31.374886] logitech-djreceiver 0003:046D:C52B.0008: hiddev0,hidraw2: USB HID v1.11 Device [Logitech USB Receiver] on usb-0000:05:00.0-2/input2 [ 40.383383] logitech-djreceiver 0003:046D:C52B.000B: hiddev0,hidraw2: USB HID v1.11 Device [Logitech USB Receiver] on usb-0000:05:00.0-1/input2 [ 60.006344] logitech-djreceiver 0003:046D:C52B.000E: hiddev0,hidraw2: USB HID v1.11 Device [Logitech USB Receiver] on usb-0000:05:00.0-2/input2 [ 60.015325] input: Logitech Unifying Device.
