Matt, I tried the new version and regardless of whether I hit "search" or "Connect", I get the same message : "Search failed to find any TinyG USB devices attached"
Some more food for thought :
if you look at the screenshot uploaded above of the USB Device Info App, you will notice that the FTDI is displayed under the "LINUX" tab, if I switch to the "ANDROID" tab, nothing is displayed.
I also tried to install another application called "USB Host Diagnostics v1.2" but this application does not see any USB device (even when I plug in a simple mouse)
Unfortunately, I think this means that while your kernel knows about USB host stuff, the ICS Android components aren't enabled on your device. You might want to follow up with the Cyanogen Mod forums to see if there are plans to provide this support, or if it should be working. The fact that the platform doesn't let you get the app from Google Play seems to confirm this. Sorry!
The app is still usable by you using the network support (connected to either my helper java program or tgFX), but it looks like the app itself won't work for you until Cyanogen provides support for USB host mode.
This is what I feared indeed. we'll see if proper USB host support will become available at a later date. I had my hopes risen when I saw I could use a mouse keyboard or external hard drive.
thank you very much for your help and dedication though.
