So as you may remember, a few months ago i got a freebie Canon multifunction device. Well it turns out its borked, and as such i'm stripping it to see what parts i can get that are of use. One little gem i found was the PCMCIA card cage, which appears to simply just be a USB -> PCMCIA adaptor that allows you to use a 16 bit Type I/Type II PCMCIA card on USB.

The device is this one to be exact.

The connector that goes to the printer's mainboard is a 5 pin connector. USB uses 5 pins. Hmm.

But...how can i get the pinouts for the connector? I know you're supposed to use a multimeter, but i've never done this before, so can someone give me a crash course? Thanks in advance
