>Description:

We have several Dell PowerEdge servers (R300, T300, 2900 and 2950) with
DRAC5 remote access cards. If I open the console (Windows Vista and
Internet Explorer) and type on the console I see

uhidev0: bad input length 8 != 0
uhidev0: bad input length 8 != 0

Every key press results two lines like that on the console which makes it
difficult to see any real information on the console. The workaround is to
switch to another VT and do the maintenance there if the host is running in
multi-user mode. However, if I need to boot to single-user mode without any
VTs, the maintenance becomes little challenging...

Apparently this happens also with SUN x4200 on the service processor console
so this is not Dell DRAC5 specific issue but something in our code.

This happens at least on NetBSD/amd64 4.x and 5.x.
