USB Cable Recommendations
If your device has a USB connector, to avoid enumeration or power issues:
■
Use a high speed USB cable that is as short as possible.
■
Use a well shielded cable with at least 24 AWG wire pair for power/ground and 28 AWG wire pair for data
lines.
■
If possible, use a USB port that connects directly to the motherboard rather than a USB port with added
cabling inside the computer chassis.
■
Use USB 3.0 ports if available. These ports are typically rated for more current.
■
You can re-order the USB cable through Multi-Tech. The part number is CA-USB-A-MINI-B-3
