These cables, while physically appearing like a normal micro USB cable will NOT work to upgrade the DM42.

That's my experience too: some cables are only suitable for charging...

Dedicated USB wall chargers with higher charging current signal devices of their higher current capability by having the data lines in the cable shorted together. Consequently, these charge-only cables won't work for data.
