Hopefully this is the place to ask this. My problem is that I have a PCIe device I'm trying to use on a home built computer. The card will only work on a full power cycle of the computer. I've tried this card on multiple motherboards and with many BIOS configurations, but no change. It only works on a hard shutdown and power up.

I'm running Ubuntu 12.10, and oddly enough sometimes the card will work on reboot when I restart from Windows 7. Same hardware. But this happens only rarely. Is there a way I can perform a reboot command, and have the power get fully cycled?

If I can't reconfigure the reboot to do a full power cycle, is there any way from the OS side to actually cycle power to a PCIe slot while the machine is on? I'm thinking that is a long shot.

Some info about my system (s)

Motherboard: ASUS P8 Z77 / ASROCK Z68M-ITX-HT / ASROCK Z77 Extreme

CPU: i7 3770K

Ram: 32Gb Corsair

Power Supply: Corsair HX 1050

PCIe device is a frame grabber to operate an industrial scientific camera
