Yup. I have a Topseed receiver too. Unlike the receiver I am working 
with, it *is* supported by the current mceusb driver. It had stopped 
working with my new Liva/Fedora/Kernel 4.X setup. But with the 
information Alec has given me, I think the problem is the same usb_hid 
grabbing the device problem.

I have patched mceusb.c and am working with the newer receiver. I will 
post if I get it working. Then I'll post about the Topseed.
