Ive got a Deneb board in my A4000D, Rev 9 Buster. The card only works without hitch by setting the jumper to force ZII on the deneb board. If I remove the jumper (ie allow ZIII) the Deneb is unstable - my USB mouse works ok, but transferring files to and from my flash card reader crashes the system everytime.
If I fit the Deneb in my A3000D the Deneb works fine in PIOMode.
