2.2.5Power Handling
Some USB devices are powered directly from the USB and do not require individual power supplies. These devices are called bus-powered devices. The USB-CAT5 Extender can provide power to these devices so they can be operated remotely.
Bus-powered devices are further divided into low-power and high-power categories. Low-power devices are allowed to draw up to 100 mA from the USB. Typical examples include mice, joysticks, and keyboards without hubs. High-power devices are allowed to draw up to 500 mA from the USB. Typical examples include cameras and keyboards with hubs. To determine if a device is high-power or low-power, consult the user documentation for the device.
The USB-CAT5 Extender can supply sufficient power to support all low- power devices and most high-power devices. Devices that place a very heavy power drain on USB (>300 mA) are not supported. Most USB devices operate well within this power budget.
NOTE
Devices with their own power source are usually considered to be low-power devices from a USB perspective and are thereby compatible with the USB-CAT5 Extender.
2.2.6Compatibility
The USB-CAT5 Extender complies with USB 1.1 specifications governing the design of full-speed and low-speed USB devices. However, Black Box does not guarantee that all USB 1.1 devices are compatible with the USB- CAT5 Extender.
