5m, thats the info i was trying to remember while chatting to Don. He was busy trying to splice usb plugs onto cat5 cable to make a usb extender, seems a recipe for disaster perhaps.
It might work: the impedances are 90 ohm [USB] and 100 ohm [cat5], both +/-15%. Even if the particular cat5 cable being used falls out of the USB spec, it shouldn't matter too much.
That doesn't guarantee that you'll get any more than keyboard-rate though (as low as 10kbps) :)
