This is a cheap, generic EBay USB 2.0 hub. It works fine, and includes an A/C adapter. Requires 5VDC, so its easy to tap into your PSU. The case is marked some from where I pried it open to peek inside, otherwise in perfect condition. I realized that I need 5 ports now that AutoTap is USB. Make sure you only need 4 before you buy. Prefer PayPal. Price for U.S. lower 48 only.
