Thanks a lot, that was the problem! Solved it by using a small hub (in the absence of an extension cord).

Hi,
I encountered a small issue with the USB ports. I am running the latest Debian testing version on my MinnowboardMax (dual core version, Rev.A2), with LXDE as GUI. So far so good. Input device is a Logitech K400 keyboard connected by using a Logitech Unifying receiver.
Now about my problem - when I connect an external USB 3.0 hard drive to the USB3.0 port (the lower, blue USB port) with the Unifiying-Receiver connected to the upper USB2.0 port, the keyboard becomes somewhat unresponsive - meaning, I type on the keyboard, and sometimes a letter shows up, but most times not. Same for the keypad input - if I am lucky, the cursor moves, but most of the times, it simply does not.
Now comes the funny thing - when I connect the hard drive to the USB2.0 port (top), and the unifying receiver to the lower USB3.0 port, everything works like a charm, besides the fact that the disk transfer speed is limited to USB2.0.
Any ideas what goes wrong? Anything I might have done wrong? I am thankful for any suggestions!
Soeren
