USB and ghost keys from keyboard.

Post by CorruptedByCPU »

Hi everyone!

A little problem with the USB UHCI driver for the keyboard (Bochs).

When I pressed the keys from 1 to 0 really fast, the result was predictable.
The second time, the 0 didn't appear, and the number 9 was duplicated.

Then I tried to press only the ENTER key a few times, but the keyboard still reported the number 9, even though I didn't hold it down at all.

Should the keyboard be somehow informed "hey, I already have it!" or I don't know :/

I have no problem with ghost movement on the mouse.

Hi,

I haven't had a chance to look at the issue you are having, whether it is Bochs related or not. However, I am curious if you found anything out.
