USB Compatibility

If your question is asking if a USB 2.0 device can be used on a USB 1.1 port, the answer is yes, though of course it will only work at 12Mb/s and not USB 2.0's 480Mb/s. The same if you meant plugging a USB 1.1 device into a USB 2.0 port. Windows XP will even tell you when you have a 2.0 device plugged into a 1.1 port. It suggests using a 2.0 port to get maximum speed. Michael Martin Australia "I controlled my laughter and simple said "No,I am very busy,so I can't write any code for you".

Thank you for the replay. I need a memory stick for an old laptop which runs Win98, it would be good for backup and transfer of data. Unfortunately i cannot figure out what version the USB port is, so i have to think about 1.0 too.
