[MinnowBoard] [Help] Communicating with an Arduino Based Autopilot

This is very likely due to that particular driver not being included by the
BSP. You can verify by determining the specific CONFIG required and
verifying it is or is not in your kernel config (/proc/config.gz). If it is,
you can verify in the driver source fi the vendor/product ID is supported by
the driver.

I suspect you just need to build the driver. If you find the CONFIG is
missing, just let me know what it is you want added and I'll update the BSP.
In the mean time, you can install the kernel dev packages and build it

We have 3.10-LTSI support in the dora branch of the minnow BSP layer
currently. I was about to tag it and release it, but let's make sure it has
the support you need first. If not, I'll add it first.
