I have a problem with wireless keyboard.

Problem is: On log, kern.log, messages and syslog is only this line.

Every second is 50 lines with such message.

Oct  1 08:14:12 wwserver kernel: [ 1447.978908] usb 7-1.3: input irq status -75  received

Because these messages is disk full. For this I have to delete log files. Please for help.

kern.log file:
