The unit was perfect for me in the form of size and functionality! There were only connected low-power HID Devices (Reiner-SCT HBCI reader) and wireless dongle (802.11.n) and HID devices (mouse and keyboard) and a USB flash drive (32 GB). Until a few days everything went without problems - until suddenly start trouble HBCI Homebanking occurred, the wireless was sporadic unconnected repeatedly and the USB stick has been repeatedly "discovered" new. Since this morning, going 4-7 the ports no longer. OK - Will submit it and then wait for compensation ....
