/dev/ttyUSB0 and /dev/ttyUSB1 not appearing

Hello,

All documentation related to the "Beaglebone" says that when you plug it in with USB into a Linux computer, there should automatically appear /dev/ttyUSB0 and /dev/ttyUSB1.

They don't for me.

Should something be done in Archlinux before this works?

What normally causes the creation of things under /dev when something is plugged into USB?

Thanks!

Apparently it adds this, very strange name:
"Bus 001 Device 003: ID 1d6b:0104 Linux Foundation Multifunction Composite Gadget"

Arch arm is a different distribution. You will need to ask on their boards.  Closed, binned.

Reopened upon appeal: issue is about an ARM device registering on an Arch desktop.

So, check what you see before and after in /dev, while you plug the device. As long as the device is seen by lsusb, the kernel recognize the device.
Maybe it will appear as ttyACM0.

My apologies to the OP. I did receive your email and I agree that I did call this one wrong. I am traveling and have been uncharacteristically out of communications.  Thanks to Jason for taking care of this

You should also ask on the support forum for the distro you are using on the Beaglebone. You may need to adjust some configuration file on your arm board to make a specific usb port behave in a special way.

Re: /dev/ttyUSB0 and /dev/ttyUSB1 not appearing

is there any useful output if you run

udevadm monitor

and try to insert the device?
