Have you tried changing the batteries in the remote?
Yes, that was one of the first things i tried because I thoght that it could be the problem.
Interesting enough the connect button on the remote also does not work
At least if I activate connecting on the USB stick it starts blinking, but the connect button on the remote does not get the green light on the usb stick to light up. It just stops blinking after some time. But the remote continues to work like before.
Can one somehow reset the remote ?
