Today I get the stroke, it is very handy and small, the slots are tight. Before I integrated him into the system, I have my whole USB driver and bodies cleaned (according to these instructions or program [...]), which I can only recommend. Then booted computer, hub drann and gradually connected to my devices. All ports in use and all recognized and connected flawlessly, even USB Stciks previously ran only on 1.1 now work again in USB 2.0. Hard drives are connected to 2 x 1Tb externemNetzteil and both work perfectly. Will leave me a few days and a little test then there is nothing for my 2nd computer nor a hub to create. Greeting hope the recession is helpful.
