USB Power
The PCIe-U300 Series provides a choice of 4, 8 or 12 USB 3.0
ports supporting Type-A USB3.0 connections on the front panel,
with 5V at 1500mA per port and extension port with 5V at 900mA
per port. It supports software programmable per-port power on/off
control for fault recovery operations.
1.5.1
Overcurrent Protection
If the USB connection exceeds a rated ICUT value due to over-
load, short circuit, or ground fault, the system protects the circuit
by shutting down the connection to PD in order to avoid an exces-
sive or dangerous temperature rise in the conductors. The recom-
mend recovery procedure is to reboot the PC.

1.5.2 Software-programmable USB Power On/Off
The AVS SDK for USB power management is ready to use with
the PCIe-U300 Series with no additional licensing required. Appli-
cations are easily created with the SDK, requiring only a few lines
of code.
