After I connect the usb WHICH "prolific usb to serial"? They have a whole slew of different models. And that doesn't count the packagers using a Prolific chip in their products (cf: https://www.amazon.com/prolific-usb-serial/s?k=prolific+usb+to+serial ) I'm guessing something similar to https://www.amazon.com/Serial-Adapter-Signal-Prolific-Windows/dp/B07R8BQYW1/ref=sr_1_8?dchild=1&keywords=prolific+usb+to+serial&qid=1625245702&sr=8-8 I can't really help with Prolific -- most of my USB<>serial devices are FTDI chips.

I got the same thing for Debian running inside VirtualBox /after/ manually selecting the USB device from the VB0x menu... BUT... unlike the BBB, my user account under VBox does NOT belong to the dialout group, so I would have not permission to use it without making changes... crw-rw---- 1 root dialout 188, 0 Jul 2 13:31 /dev/ttyUSB0 wulfraed@debian:~$ groups wulfraed cdrom floppy sudo audio dip video plugdev netdev bluetooth lpadmin scanner vboxsf wulfraed@debian:~$ sudo usermod -a -G dialout wulfraed [sudo] password for wulfraed: <logout, login> wulfraed@debian:~$ groups wulfraed dialout cdrom floppy sudo audio dip video plugdev netdev bluetooth lpadmin scanner vboxsf wulfraed@debian:~$ -- Dennis L Bieber -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
