Where can I find a USB temp sensor/relay board that works in Linux/C++?

I am currently using the UK1104 from canakit but it's driving me up the wall. At random it will fall in this mode where it just starts spitting out tons of random junk like this:

Code:
ERROR : EABOUT

What I don't understand is if I use picocom, it works fine, but even with picocom's source code incorporated into my app, it does the stupid spam shit. This makes my app completely useless as it cannot get any readings. If I use echo "command" > /dev/ttyACM0 and then cat /dev/ttyACM0 the same spam crap result can also be seen. I wish I could figure out what picocom does differently and why it works, but I'm sick of pulling my hair out.

I just want to switch out the board completely with something that will work properly all the time. I wish I was better at electronics or I'd just make my own. My requirements are that it has at least 6 inputs for Dallas temp sensors and that it has at least 3 relays. The relays can be a separate board/product. As long as both can be interfaced from within a Linux C++ app.

Anyone know where I would find such a board? preferably it should come from a company that has support. Canakit has been completely useless and just ignores my emails. I'm guessing they don't really provide support as the stuff is more geared towards enthusiasts and not for production use. I need something solid that will work the same way every time and not randomly crap out.

A bonus would be something that fits on a din rail, but that may be asking for much. At this point I just want the circuit board and I'll mount it into something myself.
