I have Scientific Linux 6.5 installed. From the beginning (on this computer) I constantly see this line jump in between all starting commands during the start up of the system (when I press
esc to see the start up log been written):
usbhid: 9-2:1.1: couldn't find an input interrupt endpoint
I had no big problem with that, so I ignored it until now. Recently I am trying to edit my programs in
emacs in a pure terminal environment (by pressing
Ctrl+Alt+F2) and in the middle of my work this line jumps in again! I wanted to see what is causing it and how I can fix this issue.
Here is an example. I wrote this text in emacs:
This is a test to show the problem. This line was a clean sentance, I kept the cursor in it to show how the line jumps in. It is not too common but it jumps in every once and a while.
After waiting a while, the line jumped where the cursor was at that moment (after "how" in the third line.):
The line remains there but only in appearance! When I press backspace on it it deletes the underlying sentance and I can only go over the region that it over laps with the undelying line.
Ultimately, when I save it, I don't see it either, futher proving that it is only there in appearance, not in the actual buffer.
When I run
lshw -c input as root, I get the following output:
