The Kindle's firmware expects to have exclusive use of that internal USB connection to the 3G card.
I don't know what you might have to change to get that exclusive access away from the Kindle's firmware while you are playing with the 3G card's command set.
(Which, by the way, I posted a reference manual on way back when.)
Since the Kindle's are known to work **WITHOUT** the 3G card working - just taking it away from the firmware is not the problem.
The problem is that many (most?) of the system files are checksum'd and the checksums stored in a manifest that is checked on each re-boot.
(Which point I had forgotten when I added a file to my K2 and then let it re-boot a couple of weeks ago. The DX is just a large screen K2 for the purposes here.)
