[Bug] Technic Hub UART: Received INFO for incorrect mode

The next step is to fix device synchronization on Technic Hub.

The debug info we get is

Received INFO for incorrect mode

It appears this is somewhat unrelated to pybricks/pybricks-micropython@8a52c95. It was happening before that in the original uartdev.c; it just showed up while debugging #1131.

On failure it reverts to the low baud rate and it works fine the second time around.

It also seems to get stuck if the cable was already plugged in on boot. This is unrelated

This has been happening all along (isn't related to new async/uartdev changes), and only seems to happen when plugging it in for the second time.

It always syncs up eventually (at low baud), especially now that we have the dcm/uart synchronization worked out well.

So I think we can down prioritize this to a future release.
