Hi,
my blue cube has been giving me problems lately.
At a certain point it seems to have been switched off or something. Keyboard won't do anything anymore. I have to unplug my blue cube, wait for about 5-10 seconds till I hear the USB disconnection notification and then plug it back in. After that it's fine again.
This has been happening more frequent lately.. and I've noticed it seems to happen when I haven't used the keyboard for a while (just using the mouse).
Any idea what it might be? USB setting perhaps?
