Hi all

This KVM uses only one USB connector for both mouse and keyboard.
I have several servers with different hardware and FreeBSD from 6.2 to 
7.1, and no one works properly the problem is: input doesn`t work at all 
OR/AND mouse moves interpretend  as keyboard pressings OR/AND input with 
like CTRL pressed, (for example if you hit "T" KVM sending SIGUSR to 
Tryed all possible bios options(Legacy USB, Fast USB, etc) .
BUT!  IF i connect PS/2 keyboard to RUNNING server, and pressing several 
key on it - miracle happens and KVM works properly for sometime...

Server info(this server interpretend mouse moves as text and keyboard 
pressings as signals):
