I have connected a USB modem to my BBB. In looking at the syslog, I see the following:

I am needing to execute a script and specify which ttyUSB* but am a bit confused on knowing which to use.

Sadly it really depends on the modem, there's really no good one standard for these guys..

Searching based on the vid/pid found:

Looks like the 2nd port is for AT commands.. Do you have any docs on the modem?

Thanks for the response Robert.

I have some guides and tutorials from the site, https://hologram.io/.

I ended up running through each one and in my script and ttyUSB2 was the winner. Which jives with what you found regarding the AT commands.
