[ipxe-devel] USB-Keyboard "roccat arvo" doesnt work properly with ipxe-menu

[Oliver Rath]

Hi list,

I have some special "Gamer" USB--keyboards (Roccat Arvo roc-12-500,
http://www.roccat.org/Products/Gaming-Keyboards/ROCCAT-Arvo/), which
work with ipxe-menu in this way:

- normal keypressing has no effect
- multiple keypressing has sometimes effect
- pressing the i.e. arrow-down key together with the shift key (or
space) works (it is important to press these keys
  at the same time) in most cases, if not, repeating this multiple times
get the
  positioning keys "work".

I assume, that these keyboards are reacting much faster than
standard-keyboards so the event too fast for the ipxe-driver.

How can I debug this? Are there implicit assumptions for the keyboard speed?

Tfh!
Oliver
