A friend of mine is wanting to put a couple USB ports on his old Toshiba 500CDT. I found a CardBus II card that plugs into his CardBus slot but I checked out Toshiba's website and it says Cardbus but doesn't say anything about CardBus II. Are they compatible? I don't want him to spend the $100 bucks to buy it if it isn't going to work. If it isn't compatible anybody know of any others like serial or printer converters to USB. I have found alot of USB to serial or printer but not the other way around.

Thanks,
Eric
