USB Power
Manufacturers don’t always adhere to the
USB specifications. You may discover that
your computer/host is not providing the full
500 mA at the upstream USB port. If your
downstream device relies upon USB power
it may not function correctly.
Here are two ways to resolve the
problem:
A powered USB isolator like B&B Electronics’
UHR401 & UHR402 will restore the full 500
mA power and provide it to connected USB
devices while simultaneously protecting them
from electrical transients.
A powered USB hub like B&B Electronics’
UHR304 will also provide 500 mA to
connected devices, while giving you
additional USB ports at the same time.
USB Range
USB has a range limitation of five meters.
You can extend the range up to 30 meters
using USB hubs. For longer ranges you can
use USB extenders.
