@Grimmers -- Many thanks for your detailed report, Since it's been more than a month, is the Pi 4 still working fine with the AD2 and is reliable.

As an update, I tried the most recent kernel updates but still no luck. The device still does not work

@ attila --Thanks for the reply and for the work you do. Does the AD2 work with other x86 Linux computers running kernel 4.+ What version of the kernel do those other SOCs run? Edit to add: I am looking at https://github.com/raspberrypi/linux/issues. Maybe a post there may get some help.

Just to add, that I've tried it with the recently released Raspberry Pi 3B+ but no luck. I have updated to the latest kernels. Very frustrating I wonder if there is a problem with the Digilent Adept runtime drivers for linux.
