Hello, |
| 2 |
|
| 3 |
After compiling kernel-3.8 (plain vanilla) I begin to see lots of these |
| 4 |
entries in the kernel log: |
| 5 |
|
| 6 |
usb 1-1.3: USB disconnect, device number 4 |
| 7 |
usb 1-1.3: new low-speed USB device number 5 using ehci-pci |
| 8 |
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 |
| 9 |
|
| 10 |
These entries are repeated, with the device number increasing (+1) |
| 11 |
each time. |
| 12 |
|
| 13 |
The odd thing is that these USB disconnects occur only in console mode. |
| 14 |
My system boots up to the console and the messages appear roughly every |
| 15 |
60 seconds. But when I start X, the messages suddenly stop. There may |
| 16 |
be only one or two USB disconnects over the next 12-16 hours. The only |
| 17 |
difference between console mode and X is that the mouse is only active |
| 18 |
under X. |
| 19 |
|
| 20 |
The system remains stable, but for some reason, the USB mouse will repeatedly |
| 21 |
disconnect in console mode, but also rarely in X. |
| 22 |
|
| 23 |
I have searched for references to the problem but could only find a |
| 24 |
possible similar issue with 3.8-rc1 |

Has anyone else seen this "USB disconnect" problem with kernel-3.8.x? |
| 29 |
|
| 30 |
It could be that my motherboard is failing (it's approx. 2 years old) but |
| 31 |
then why would the USB disconnects suddenly halt under X. |
| 32 |
|
| 33 |
USB is built in to the kernel; there are no USB modules loaded. |
| 34 |
|
| 35 |
Any comments on how I could investigate this further would be appreciated. |
