I've found that if I hook up something that doesn't "just work" (and the blue smoke doesn't burst forth), I have to step back and break things into smaller steps. Does each part in isolation work?

  1. can you get the board to work with another computer? The hardware manufacturer will have some sort of documentation to attach it to something, like maybe a PC. So, hook it up to a PC and learn how it acts (blinkie lights, data sent via usb, etc.).

  2. is your Raspberry Pi happy? does it boot and work normally w/o GSM attached.

The process of getting this far will teach you things you'll find helpful going forward.

  1. from the shell start doing USB commands. e.g. lsblk, dmesg with the GSM unhooked and then after you plug it in. Do not fear plugging-in/unplugging GSM usually. I've found that when I'm lost, looking at the change of lsblk output (when I unplug, then plug in) can tell me something helpful.

  2. start haunting the board's website/blog/git-repos and duplicate what you find there. They know best how to the board works. They know how they verify their product is working, and they should be willing to share troubleshooting hints with you. Remember, their motivation is to sell a working product, not solve your problem, don't be too demanding.

Good luck. (and work to improve your luck)
