Are you also opening it up a bit so other mining software like BFGMiner and MultiMiner can run these?
I am really liking my DualMiner it is just a pain to run separate mining software programs for them.
The firmware on the device is not upgradable. We don't need upgrade it actually. The firmware just convert USB to serial. Start from next version, our Windows GUI app will be upgradable. About PC Linux or ARM linux, since we will open the source code, users can upgrade to new version source code. To do a Linux upgrade, the user need have some experience on Linux.
Yes, BFGMiner and MultiMiner can run dualminer devices if the code merged into them.
