DW1820a - the general troubleshooting thread
I followed @Hervé guide for 7490 with much success, but minor hiccup on wireless card access.
Not sure if it's just my luck, or I got conned, but the DW1820a OVW3T3, which should work great in this setup, faces performance issues once wifi network is connected.
I read @Hervé guide on wireless cards so many times, until I noticed that the subsystem ID, which should have been 1028:0021, is showing up as 1028:0023. I'm basing this info on the system profiler picture attache
Finally had DW1820A working in my build.(Everything but Unlock with Apple Watch Feature)
I taped several pins but I don't think they really matter.
