The fix for this will hopefully be implemented in the next release but here is the fix in meantime:
Plug in the usb stick/disk and edit these files in notepad or somesuch:
in /boot/syslinux.cfg you need to edit this line:
APPEND label=BATOCERA console=tty3 quiet loglevel=0 vt.global_cursor_default=0
so that it looks like this:
APPEND label=BATOCERA console=tty3 quiet loglevel=0 vt.global_cursor_default=0 usbhid.quirks=0×2563:0×555:0×040
(everything in one line)
Edit also the /EFI/syslinux/syslinux.cfg with the same info.
This should fix the ShanWan Twin USB where you have 2 wireless controllers in 1 usb dongle.
