Yep, you're right.
Here's another wild guess... find line 528 in do_identify():
if (dev->version < 20300000) {
...and change the version number to 20404000 (or anything else which is
greater than 20401004).
Older versions of the firmware return a device name string, and newer
versions won't. I just don't know how new exactly.
