I think that if the device is left to errorneus state without

re-trying, it shows up to user very annoying. For example:

My mouse now has the problem with buttons: if i click left

button -> nothing may happen, and it is not functioning until

right button is pressed once. I make adaption to divide the

timeout by 100, and keep the try-loop in core.


I dont have list all the drivers that needs this -> better fix at

one common place.
