KVM switch prevents 'Space Bar' from powering PC

I used to power up my PC by it’s space bar, but since I began using a KVM switch, it no longer works that way…yes, even if I’m ‘KVM’d’ to that computer. If I remove the KVM, I can boot from my keyboards space key fine, so it’s got something to do with the KVM for sure.

ASUS P5KC mobo - set to power up in the BIOS still
Wireless Logitech keyboard - works without a KVM in line
Belkin F1DS104L 4 port KVM - with “hot keys”

Anyone know why the KVM prevents the space key from booting the PC? It’s easy enough to use the towers power button, but I quite like the keyboard option of powering up :slight_smile:
