Hello all,

In short, I've always left my PC on at night and it goes to sleep with no problems, but for the last few days it's been waking itself up several times a night. The bizarre thing is that, according to the events log, it's always at a time ending in 4 and always after a period of sleep of either 1h, 1h 10m, 1h 20m, 1h 30m, 1h 40m, etc, up to 3 hours. So, last night for example, it woke up at 0.44, 2.54, 4.14, 5.24, 6.24, 7.54.

The source is always described as USB Root Hub. I've tried disabling wake on LAN, keyboard and mouse to no avail. It's Windows 7 Ultimate 64.

Many thanks in advance for any help, 'cause I'm baffled!
