What does it mean when all three LED's (Num Lock, Caps Lock and Scroll

It doesn't happen on all the systems I plug it into, just one.

I'm guessing maybe the one host system can't support the keyboard
power ????


What model number keyboard? And what is the offending system?

It may be more than a simple power problem (I'd just expect nothing to
work). Its probably a failure signal either from the keyboard processor
itself or the PC's BIOS


Belkin F8E-206-USB. "Offending system" is IOGear HCS1734 KVM.


OK, I was thinking of a PC as a host system. Sounds like the KVM is
continually rebooting. Many keyboards blink their LEDs upon startup, but
no PCs can cycle so quickly that one would describe a repetitive blink.

Do you have a powered USB hub lying around? Try putting that between the
KB and KVM.
