Notes & Compatibility
Any USB-A to USB-B cable works — same as printer cables. The most common failure mode is a physically loose USB-B socket on the interface after years of use, not the cable. If you get audio dropouts, try a replacement cable first. Keep under 3m for best results; 5m is the USB 2.0 spec limit.
