RPi 4 (emteria.OS v11.2.0) - USB-RS232 driver problem
We test sending USB-RS232 commands using Aten UC 232A. And we came across a problem where RPi4 does not register Aten USB-RS232 as ttyUSB0, but as xhci_hcd. On RPi3 (emteriaOS 1.3.0) everything works properly, Aten registers as ttyUSB0 (pl2303) and commands can be sent to it.
We want to ask why the RPi4 USB-RS232 converter registers badly and not like ttyUSB0?
