Need sudo to access device.

[ntn888]

I'm on Arch. I can use the device if I sudo. I also tried installing udev rules as follows (provided by sigrok package). However to no effect. Is there anything I need to include here?

@ntn888 you need to add yourself to the group your distro uses for serial ports.
Example under debian (lines starting with $ indicate commands you must enter into a shell or terminal program):

run sudo dmesg -w and then attach device:

$ sudo dmesg -w
[ 3803.735577] usb 5-2.3.3.4: new full-speed USB device number 21 using xhci_hcd
[ 3803.904699] usb 5-2.3.3.4: New USB device found, idVendor=16c0, idProduct=27dd, bcdDevice= 0.10
[ 3803.904704] usb 5-2.3.3.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3

[ 3803.950739] cdc_acm 5-2.3.3.4:1.0: ttyACM1: USB ACM device

device name is "ttyACM1"

$ ls /dev/ttyACM1  -la
crw-rw---- 1 root dialout 166, 0 Jul  8 18:02 /dev/ttyACM1

the group owning the serial port is "dialout"

$ echo $USER
nine

my username is nine, so add myself to the dialout group:

$ sudo usermod -a -G dialout nine

and then log out and back in again so that your permissions are correct for all applications
