I just got a USB 2.0 PCMCIA CardBus card with 2 USB ports and a hole for an optional AC adapter. When I stick it in my Gateway 600YG2 laptop, the computer instantly powers down. I've tried it in both PCMCIA slots with the same result. I suspended the slots with pccardctl before inserting the card, and the computer still powered down.
I have Linux From Scratch, with udev upgraded from 056 to 096 and hotplug removed. Before I upgraded udev, I copied the entire OS onto another partition. The copy is still there, complete with hotplug and the old udev. I booted it and inserted the card, and the computer still turned off.
When I insert the card with the computer off and then boot, it powers off during the booting process. It happens before sys.log, kern.log or any other logs are written to.
Could I have bad hardware?
The card is some kind of "no-name" brand. It says "Best Connectivity" on it.
