Can’t find a Linux (Ubuntu) serial CP210x driver.
Checked the silabs web site and they don’t seem to have a current driver for Linux.
CP210x Linux driver?
Just figured out that I was using Linux mint which does not have the driver.
Ubuntu does have the driver!
Linux has the driver and it shows up in the list from lsusb.
However, the Meshtastic flash utility using Chrome can’t find it.
