Bit of an odd one.. We have a Garmin
GPSMap 8610 and I have my RP4 (64bit) connected to it. The screen
display works well.. now I'm trying to get the touch portion working. When I plug
in the USB cable the Rpi see is and seems to install ok, but It doesn't work
(not too surprising I think), any ideas on the drivers needed to get it going?
