    Sorry about late reply, I wanted to know which cable, that is, serial or USB. Also i wanted to understand difference between USB 1.0 and 2.0 - mostly for speed and distance.
    I plan to use USB 2.0 / gold plated for higher speed - want to use about 15 feet of extention cable with existing USB cable...I am not sure if i have USB 1.0 or 2.0 cable that came with signature pad. As a result, i was concerned about compatibility since signature pad sometimes fails to recognize network connectivity due to USB extention cable being 1.0 or 2.0; therefore, i was wondring if i should use USB or serial...

    Hope i am clear in what i should be asking...
    I hope some one can help.

    I think any USB cable will work for any version of USB as long as you have it correct as far as type A or B. Check out Wikipedia's article on USB (link in Rick's post). Low speed is 1.5Mbit/s, full speed is 12Mbit/s, and high speed is 480Mbit/s.
    Hope this helps.
