There are two very common problems when using the USB interface. The first involves a mismatch between the USB version on the PC and the version on the TDT rack. When a TDT rack is using USB2.0 modules, the PC must also have USB2.0. The opposite setup (USB2.0 on the PC and USB1.1 on the TDT rack) should be compatible. Also, racks will not work together if there is some combination of USB1.1 and USB2.0 modules on the TDT racks. If you are not sure what USB ports are on your PC then you can 1) check the PC manual or 2) assume that it is probably 2.0 if the PC was purchased new within the last 3 years.
