Attempting to mount storage for transfer from my old Pre to my linux box...

After some progress (installing drivers, getting novacomd to run) I'm now stuck at unable to find device when trying to run novacom or novaterm. At first, I thought maybe it was because I wasn't in Dev Mode (and my screen won't accept input); then I remembered the old "konami code", so that's all set now.

I'm hoping someone has some thoughts as to what may be the problem. If it matters, I'm running Arch/Manjaro 4.10.17-2

Many thanks!
