Full disclosure: I work for MXI Security.
Incorrect. There is no "remote control" protocol for devices. Device
communications with MXI's ACCESS Enterprise Manager software are
currently all local to a single PC.
Tasks like password resets are done with a challenge-response process
meant to take place out-of-band (e.g. over the phone).
You're right, though, in indicating the danger of weak communications
protocols, whether they're across a network or not. I don't want to
do a sales job here, but every device we've released this year
supports the NIST SP800-56A key agreement scheme -- the first and
only line of USB drives to do so. That's the kind of thing you want
if you're relying on a server for security features.

Incorrect. All MXI drives support password authentication (either
alone or in conjunction with biometrics or a CAC/PIV smart card) and
all password verification here is done in the device itself.
All biometrics on MXI devices are also matched in hardware -- the
"helper" software telling you to place your finger is just that, a
helper. The dual LEDs on the device provide the same info more
succinctly.
It is correct, however, that devices that have a software component
may well leverage their hardware security improperly (as occurred
with some competing products recently). This is not the case with any
MXI Security products -- all verify their password (and any other
authentication mechanisms) in the device hardware, not in software.
