lsusb for bcdDevice 25.20
Okay, managed to compiled the module with the fixups option and loaded.
Unfortunately, although the module loads without problems, the BT adapter
won't work.
hciconfig hci0 up
ends in connection timed out.
I attach the full lsusb -v output for this device. Is there any other
helpful info I can provide? Being able to solve this would be great, as in
my country all the BT dongles I've seen online are CSR dongles.
Same here. I managed to compile the module on kernel 5.4.6 with the patch that
has the fixups made by Fernando Carvalho, but the symptoms are the same as
without it; no bluetooth adapter found with bluetoothctl or any other front
end.
Dmesg shows the patch and the fixups are indeed applied.
