[SOLVED}How to find Arduino Serial Port

I'm having trouble finding the serial port being used by my arduino. The wiki suggests /dev/USB* or /dev/ACM*, but I see none of those. I'm also not sure what I would use to check everything.log. Thanks

EDIT: A reboot showed the port after the command dmesg. Logout did not seem to be sufficient.

Re: [SOLVED}How to find Arduino Serial Port

Remove the cable, run dmesg. Then plug it in and run dmesg again. Should show you some output pertaining to where its located.

Re: [SOLVED}How to find Arduino Serial Port

Tried that, says new usb 3-1: new usb full-speed device number 12 using ohci_hcd. Does that relate to a certain tty in /dev? I'm not sure

Re: [SOLVED}How to find Arduino Serial Port

Can you post output from what you have been doing? dmesg, lsusb, etc etc. Does it say anything about the type of device?
example:

Bus 005 Device 007: ID 0451:2046 Texas Instruments, Inc. TUSB2046 Hub

Is your system up to-date?

Re: [SOLVED}How to find Arduino Serial Port

@duke11235: the wiki suggests /dev/ttyACM*, you seem to have forgoten the tty part in your first post.

I'm getting this when typing lsusb:

Bus 004 Device 012: ID 2341:0043

It has no description as you can see, it is an empty line. I do not know if this is normal, I got my Arduino a few minutes ago so some things are new to me

Dmesg reports this:

[ 1962.272292] usb 4-1.6: new full-speed USB device number 12 using ehci_hcd
[ 1962.359384] cdc_acm 4-1.6:1.0: ttyACM0: USB ACM device

Re: [SOLVED}How to find Arduino Serial Port

Is there a question there? Your dmesg seems to show an arduino at /dev/ttyACM0, so put that in the arduino config file under serial port and you should be fine.

Re: [SOLVED}How to find Arduino Serial Port

Well there wasn't really a question, more of a wandering (why lsusb doesn't recognize).

Everything works fine, by following the wiki smile
