Aren the requirements for cables different at the new higher speed or will Original USB cables work with Hi-Speed USB?
Fully compliant Original USB cables will work fine at Hi-Speed USB speeds. USB cables are not all fully Original USB compliant and it is important to evaluate cables that you intend to include in your products. The USB-IF has started a program for accurately testing cables to make it easier to pick a good quality USB cable that will work correctly for both Original USB now and Hi-Speed USB in the future. You should look to the Integraters List on USB-IF Members-only section of the USB-IF web site (you will need to input your USB-IF username and password to access it) to identify products that have passed that testing program in order to minimize your risk of customer problems caused by poor cable quality.
