Hi Community,

just bought this USB 3.0 Hub device from Sharkoon:

http://www.amazon.de/gp/product/B008PSL45Y/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1

It uses the Renesas Electronics third Generation USB 3.0 Host Controller. It comes with a 5A power supply and has 4 Ports. I'm using it with a PI Model B and the latest Raspbian from the official site. So far so good, here are my test results:

I'm powering my PI over one of the ports. My Pi works very well running @950 Mhz. Under Raspbian, i think the device gets recognized, although Raspbian is not showing it's name. When i attach different usb-flash or hard-drives to the hub, they all work well (even my external WD MyPassport USB 3.0 ntfs-hd!). Unfortunately, the hub does not recognize any usb-keyboards or mice attached to it and only 3 of the 4 ports are working. Under Windows the hub works fine, so it's not a hardware issue.

Is this a kernel or configuration issue? Appreciate your help!

Here is an extract of lsusb -v:

BTW, I love my Pi (using it mainly as a LAMP development server for my coding and xbmc of course!)! Back to the roots... i feel like in my old Commodore 64 days;)
