Maybe try my test version of something after 1.9.4 but not quite 1.9.5
yet?

I found several flashing issues when upgrading firmware versions which
have different code.
On Linux, if you run altosui from a terminal window and enable 'Serial
Debug' in the 'Configure AltosUI' dialog, you will see a bunch of
messages that describe the process of reflashing; capture a broken
session of that and send it along.

I would suspect some kind of serial communication problem with the USB
dongle; I've never heard of anyone having anything like this.
