I tested with my RX888MK2, it finds it under modules, it tells me that the Firmware is loaded, I can see it under LSUSB.

But it won't start, keep telling me this, tested various USB-3 cables even the original it keeps saying this:

fern-rx888 0.1.0 with libusb 1.0.30
no RX-888 is plugged in. Check that it sits in a USB 3 port and that lsusb lists Cypress 04b4:00f3 or 04b4:00f1
fern-rx888 0.1.0 with libusb 1.0.30

I know it's working as it's my testing system. Looks to me the module doesn't detect it properly.

I appreciate the testing, this seems like a bug. I will put this into the 0.1.2 version which should be out later today :)
