Hi All, I know some of you out there have dabbled with usb so i thought this would be a good palce to ask. Inside my PC i have a USB header, this is already used to run my wireless lan card, but i want to add a memory reader to it - can i simply daisy-chain the two devices? It is Universal _Serial_ Bus after all right? Additionally, looking at the usb header it looks suspiciously like there are two usb channels there anyway, but the connector for the wlan card uses both of them - is this because it is usb 2 or for some other reason?
