System Operation
No drivers are required for a host PC to function with the USBExtender Plus T/R. The
transmitter is detected by the operating system and appropriate USB drivers are loaded.
Certain USB peripherals, such as gaming keyboards, USB interactive whiteboards,
scanners, printers, and similar devices, require specific drivers installed on the PC. See the
USB device installation instructions or the website of the peripheral device manufacturer to
obtain drivers.
Once the transmitter, the receiver, the PC or USB host, and peripherals are connected, have
appropriate drivers loaded, and are powered up, the system is fully operational. If problems
are encountered, ensure all cables are routed and connected properly and the latest drivers
for each peripheral are installed.
