I have a bunch of Allwinner H6 boxes branded as "MX10Pro 6K" (pic easily searchable in google), which seem to be a derivative of Tanix. What's more complicated that I have'em of two different hardware revisions (don't really know what the vendor revision tag is, but they look slightly different and work radically different). So, say I have 1 box of older "A" revision and 10 of more recent "B". I run them with sun50i-h6-tanix-tx6.dtb profile on latest Armbian_21.05.0-trunk_Aw-h6-tv_buster_current_5.10.27
image. The "A" revision works just fine, but "B" one has only one of 4 USB ports working.
Any chance I can make the other 3 work ? What info should I provide to diagnose why they don't work ?
