Hm, ok, it could be. However, I see no evidence in any logs that it is 
actually having problems with loosing contact... What should I look 
for? But then, there are quite a lot of cables here; first the normal 
cable to a 5m extension cable, which again is connected to the Tangtop, 
which is connected to the USB port. If any of those gets displaced, 
obviously, it can happen easily. But then, she was just typing 
carefully when it happened. 

BTW, it happened a second time just after I wrote my post. 

Then, it didn't pour out events, it just sat there. Also, in the first 
case, DPMS didn't blank the screen, in the second case it did.

OK.

Ouch, yes, that's rather bad.

If there is anything I can try, please let me know!
