Howdy, my very old thinkpad 600x only has one usb 1 port which is pretty slow when transferring any sizable file, thus I want to get a pcmcia usb 2.0 card. However all the ones I look at have some mention of bein powered via an included usb cable. Most state that they can only supply 100mA per port without the cable, or 500mA with the cable.
Apart from external hard drives what sort of devices would 100mA struggle to power?
Also does anyone have experience with one or can recommend a particularly good card, rep left for useful help!
