Hello;J&R.com sell's a 20-Foot High-Speed A Male to B Male USB 2.0 Cable.Will this length 20ft. work ok with Windows XP Pro Sp3 for a printer.? Just asking because I thought 16ft. was the max.for USB.I was told that by someone,but I could really use this 20ft.one for the added length.Thankyou for any info.
