I have mouse Logitech M505 and keyboard Logitech K340 on same usb wireless receiver. My Ubuntu is up to date.

Problem is that sometimes ubuntu doesn't recognize devices - Lately very often. I seat in front of my login screen and I can't do anything. Even blinking cursor stops in welcome password field. Mostly hard reset is a rescue.

Sometimes helps when I unplug Logitech usb reciver and plug it again, wait about 2 minutes and try to hit some buttons on my keyboard. Then there is a chance to back to live those two devices.

In my Windows 7 everything is all right.

System: Linux version 3.5.0-22-generic (buildd@komainu) (gcc version 4.7.2 (Ubuntu/Linaro 4.7.2-2ubuntu1) ) #34-Ubuntu SMP Tue Jan 8 21:47:00 UTC 2013 CPU: AMD Phenom(tm) II X6 1100T

syslog when I plug receiver again:

ok , so i got logitech m525 wireless mouse with unifying receiver, just happen for a second time that it out of nowhere stopped working.

I would like to note that it's second time that's happening, for a first time i got my mouse replaced by warranty.

So the thing is that i use this mouse with my laptop which i carry to work for and use it a home more or less daily, so it's approximately(at least) 2 cycles of in/out daily.

And even nicer thing is that why i decided to write here is: if you put the unifying receiver only half way inside usb socket it start to work, so the thing is that unifying receiver wears out due to sadly not that intensive use.. maybe it's not the windows thing?

(if you thing that it's single usb socket's issue, no it's not, it's the same with all 4 i got on my laptop)
