Hello,
After compiling kernel-3.8 (plain vanilla) I begin to see lots of these
entries in the kernel log:
usb 1-1.3: USB disconnect, device number 4
usb 1-1.3: new low-speed USB device number 5 using ehci-pci
input: Microsoft Microsoft Basic Optical Mouse v2.0 as /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.3/1-1.3:1.0/input/input2
These entries are repeated, with the device number increasing (+1)
each time.
The odd thing is that these USB disconnects occur only in console mode.
My system boots up to the console and the messages appear roughly every
60 seconds. But when I start X, the messages suddenly stop. There may
be only one or two USB disconnects over the next 12-16 hours. The only
difference between console mode and X is that the mouse is only active
under X.
The system remains stable, but for some reason, the USB mouse will repeatedly
disconnect in console mode, but also rarely in X.
I have searched for references to the problem but could only find a
possible similar issue with 3.8-rc1

Has anyone else seen this "USB disconnect" problem with kernel-3.8.x?
It could be that my motherboard is failing (it's approx. 2 years old) but
then why would the USB disconnects suddenly halt under X.
USB is built in to the kernel; there are no USB modules loaded.
Any comments on how I could investigate this further would be appreciated.
