Hi Matthew, user is in the dialout group, which is the correct group for /dev/ttyUSB0.
rabbit@ganymede:~$ cat /etc/group | grep -i rabbit adm:x:4:syslog,rabbit dialout:x:20:rabbit cdrom:x:24:rabbit sudo:x:27:rabbit dip:x:30:rabbit plugdev:x:46:rabbit lpadmin:x:120:rabbit lxd:x:131:rabbit rabbit:x:1000: sambashare:x:132:rabbit rabbit@ganymede:~$ ll /dev/ttyUSB0 crw-rw---- 1 root dialout 188, 0 Apr 6 19:10 /dev/ttyUSB0 I wasn't sure that there may be a new graphical device manager I did not know about in Ubuntu. And why not? I don't think there is a System menu, either! So back to the command line...I started with Slackware 0.96, so not a noob to Linux, but it has been awhile since serious sysadmin hacking and never before any serial work. I am a noob to Chirp. As I mentioned earlier, my ham radio appears to be on /dev/ttyUSB0: rabbit@ganymede:~$ dmesg | grep tty [ 0.108706] printk: console [tty0] enabled [ 0.396467] 00:05: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A [ 0.418518] 0000:00:16.3: ttyS4 at I/O 0xf0e0 (irq = 19, base_baud = 115200) is a 16550A [ 3.348131] usb 1-1.1.3: FTDI USB Serial Device converter now attached to ttyUSB0 Kindly, Robert . .. ... ‘...^,^ ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Tuesday, April 6th, 2021 at 7:21 PM, Matthew Poletiek <[email protected]> wrote: > I'll just add you can see your current groups with; > > `cat /etc/group | grep -i <username>` > > Matthew Poletiek > > 303.810.9082 > > [email protected] > > www.matthewpoletiek.com > > On Tue, Apr 6, 2021 at 6:20 PM Matthew Poletiek > > [email protected] wrote: > > > Hi Robert, > > > > You might want to check to make sure your user has proper permissions. > > > > In linux, typically the groups you might need for this kind of > > > > operation include `dialout`, `usb`, and while you're at it you might > > > > as well include `plugdev`. > > > > The command to add your user to a group might be `sudo gpasswd -a <user> > > group`. > > > > Once thats finished you might need to refresh your profile.
