This small USB hub packs a 4-port, high-speed punch into a small form factor. Measuring only 2 3/4" across and 7/8" thick, the hub features a status LED for each port, so you can easily monitor the activity on each line.
The included cable is about 29" long and has a standard USB A male connector on one end and a mini-B male connector on the other. For high-power situations, an optional AC adapater can be used to provide power to the hub and any connected devices. The optional power adapter uses a DC connector with a 3.8mm barrel and 0.7mm pin size. The power adapter is not included.
As with any USB 2.0 device, it is backwards compatible with earlier USB versions and compatible with any computer system, operating system, or device that complies with the USB 2.0, 1.1, or 1.0 standards. USB is a hot-swappable standard and this hub fully conforms to that requirement.
