Microsoft Wireless Multimedia Keyboard doesn't work on kernel debugging land

Description
Pressing Alt-SysReq (R Sist on the Micro$oft keyboard) - D you obtain correctly the kernel debugging land prompt (and it recognized correctly that the keyboard is USB) but then when you try to write nothing happens... you've to found a legacy PS/2 keyboard to do your operation and press "co" to return to the OS. After OS is "restarted" the wireless keyboard is working again correctly.
Maybe using a wired USB keyboard is used it works, but I not have one, I've only a legacy wired PS/2 keyboard!

That's not actually a bug. Normal OS operation and KDL are two totally different things, the KDL is a highly limited environment. Only limited USB keyboard support has been implemented. For example it requires being hooked to a UHCI root port right now, so not a hub and not an OHCI controller.

Replying to mmlr:
Only limited USB keyboard support has been implemented.
Are you saying that my issue should be filed on a separate ticket?

I don't know about the reporter, but now my usb keyboard works in gdb and kdl prompts on hrev36336. Thanks.

Correction:
If the system goes int gdb the usb keyboard works and I can use ALT+SysRq+D to bring up KDL where keyboard also works.
I system goes into KDL directly, the keyboard does not work and only recourse is a hard reset.

That's a known issue that applies to all USB keyboard, for them to work in KDL you have to enter and leave KDL manually at least once first.

I'm trying ALHA2 now pressing ALT+SySREQ+D does nothing anymore using my USB WIreless keyboard... well maybe is best: as you MUST reboot to exit in that case.
So, sorry, it is not solved for me!

You may want to test again. There have been many changes in the past 19 months. On my system, I no longer need to enter and then leave KDL manually for my keyboard to work in actual KDL crashes.

Assign tickets with status=closed and resolution=fixed within the R1/beta2 development window to the R1/beta2 Milestone
I have the a similar issue with my wired usb keyboard. However, my system does not have any ps/2 ports, just 10 or more usb ports, so when it enters KDL or some gdb screens all I can do is do a hard-reset.
