Hello,

My syslog is constantly filled with messages like this:

Oct 16 11:48:35 my-laptop kernel: [61470.980078] hub 1-0:1.0: unable to enumerate USB device on port 2
Oct 16 11:48:35 my-laptop kernel: [61471.192079] hub 3-0:1.0: unable to enumerate USB device on port 2

The only USB device I use is Microsoft Natural Wireless Laser Mouse 7000. The laptop model is HP dv9500, Ubuntu 10.10, but the same was in the versions before.

How can I fix this?

Edit:

Here's the output of sudo lsusb:

Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 003: ID 045e:071d Microsoft Corp. 
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

All USB devices seems to be working fine. I have some problems with DVD-R and sound card, but they are not USB.
