I have occasional communication errors over USB. What is the problem?

The first thing to check is the USB cable.  Because of the bandwidth of the data being transferred over the USB, a standard USB cable will drop messages every so often.  This will lead to communication errors.  Therefore, confirm that the USB cable being used has a noise suppression choke. See the photo below.  A shielded cable is also advantageous.


We offer filtered USB cables, which we typically recommend to our customers on their first purchase.  The part numbers are:

- CBL-USB-L3-S (A to B, 3 ft)

- CBL-USB-L3-M (A to mini-B, 3ft)
