I've finally figured out why I am able to get 12.0 Mbps USB modem port
speed with the V3xx tethered to one Windows XP computer with DUN
(dial-up networking), but only 921600 bps on another similar Windows XP
computer.

When setting up a new Windows XP installation I was able to get 12.0
Mbps port speed when tethering the computer to my V3xx with the Motorola
Handset USB Driver you have available for download. I was still able to
get 12.0 Mbps port speed after installing Motorola Phone Tools version
3.11, as well as after updating it to version 4.3.6c (the latest version
that doesn't exhibit the USB driver crash I reported in Reference Number
070709-000012). All well and good.

However, after pairing the V3xx with that same computer, which installed
it as a Bluetooth Modem, the maximum port speed for the Motorola USB
Modem dropped to 921600 bps, the same maximum as the Bluetooth Modem.
Apparently, pairing the phone with Bluetooth changes the Windows XP
configuration in a way that prevents the higher 12.0 Mbps port speed for
the Motorola USB Modem.

I tried uninstalling the Bluetooth modem, and deleting the V3xx from
Bluetooth, but that did not restore the 12.0 Mbps port speed.

I then tried uninstalling and reinstalling the Motorola USB Modem, but
that did not restore the 12.0 Mbps port speed either.

I had to use System Restore to roll back the Windows XP system to a
point prior to Bluetooth pairing of the V3xx, whereupon the 12.0 Mbps
port speed was restored for the Motorola USB Modem.

The "you" here is Motorola. (I posted this message first to Motorola
Developer Support on the Motorola Developer website at
<http://developer.motorola.com/>.)

The Motorola USB Modem driver is available at
<http://developer.motorola.com/docstools/USB_Drivers/Handset_USB_Driver/>

The USB driver crash refers to a crash of Windows XP SP2 when Resuming
from Standby if a Motorola handset was connected to the USB port when
entering Standby and removed while in Standby (before Resuming).

According to Motorola Developer Support, the actual cause of the crash
is a bug in the Microsoft toolkit they use for the latest versions of
the Motorola USB Modem driver, but one that Microsoft doesn't seem to be
interested in fixing.

12.0 Mbps port speed is noticeably snappier than 921600 bps port speed
when tethering on a "3G" (HSDPA/HSPA) connection.

Obviously you do, Kevin, because you make an immature a.s out of
yourself every time you see something from me, no matter how worthwhile.
Grow up and get a life. Or if that's beyond you, just filter me out.
Seriously. In the meantime, back to my twit filter you go.

Thanks for proving me correct. As I remember last week you were to kill file
me. I threw that out there as I knew you could not stay away. Please kill
file me. I'll re-test you again soon. You think anyone here likes to read
your useless post's ? You just like posting BS to start your "I'm lonely and
no-one likes me crap) So go back to posting your Motorola FAQ BS that no-one
reads or care's about.

(I know he will reply) : ) God, I can't wait for the POS To reply.

I would never add you to my filter. Your too fun to give crap too.

Funny that I said the same thing. That pissed you off so you say the same.
Sorry, Tricks are for your silly a.s. Somehow I knew you would try to get
out of your lies.

Oh come on, Navas never lies...except when he's typing on a keyboard.
