I'm not sure if there's a way to get it separately from that (it's not
'just' a standard RNDIS driver, as I understand it). Nothing new is
required on the device. The Advanced option is set via the ActiveSync
application on the device.

So, it's still unclear to me why you're trying to connect to a server on the
PC at the same time as you're trying to reconfigure the WiFi and why you're
doing it for so many devices at once. I can envision some sort of
'provisioning' operation where you connect to the PC server, ask it for the
right WiFi parameters and reconfigure the WiFi, but, once you've got the
information, I don't see why you'd need to be connected any more (why you
couldn't connect the devices one at a time). If you used ActiveSync, the
means to get the provisioning information would be many. You could have IIS
running on the PC and get it via the Web browser on the device. You could,
if you really want to, have a TCP server with your own custom protocol, of
course too; it's just more work. If this is a one-time-only provisioning
operation, it also seems like doing that before putting the device in
service would be even easier. No server, no network client, just a program
to set the WiFi settings based on an XML file, say. Are you expecting the
devices to travel from one 'configuration station' to another or the WiFi
settings to change frequently?

If you plug just one in, does *that* show up? If not, you don't have the

switch).

How about answering the question that I've asked three times now?

Anyway, why can't you just use WiFi for all of your communication?

If that works, then you have your communication channel. All

just communicate with the PC over WiFi -- you can't do that?).
There
was
a
recent thread in microsoft.public.pocketpc.activesync where a
guy
came
up
with a means of preventing WM5 from dropping the WiFi connection
(he's
using
an NDIS intermediate driver to ignore unbind requests from
ActiveSync
to
the
WiFi connection; not my favorite way to do it, but it should
work).

Seems to me like you should be able to. If I understand
correctly,
if
that's the case, you should be able to remove ActiveSync from
the
PC
side,
leaving the USB RNDIS driver for the mobile device installed.

Are you the host or the device on USB? If you're the host
and
you
can
make
the external device look like a network device, you could
do
what
ActiveSync
does, except in reverse, I guess. If you're the client,
you
could,
in
theory at least, use what ActiveSync does, without
ActiveSync
itself.
You
look like a USB RNDIS adapter and, as long as the suitable
PC-side
driver
for USB RNDIS is installed, everything should work just
like
when
ActiveSync
is running, but you don't have to sync.

I think you're going to have to tell us what sort of a
device
this
is,
whether you are the device OEM and are in control of the
OS
development
or
not, who is the host and who is the device on the USB
connection,
etc.

Is there a way to do TCP/IP communications over a USB
connection?
Preferably one that does not involve active-sync.
If anybody has any samples or can point me to the proper
API
calls,
I
would appreciate it.

Thanks,
PaulH

What I'm looking for is a way to communicate with a group
of
WM2005
and WM2006 devices over USB. The PC would be the server and
the
WM2005
devices the clients, in this case.

I looked up RNDIS as a possibility, but haven't seen a
whole
lot
in
the way of examples for using that online. Are there any?

I have access to all of the OS development libraries.

Thanks,
PaulH

I'd ultimately like to be able to control the 802.11
connection,
so
I
can't actually use active-sync even as a guest since it
does...unfortunate things to the 802.11 radio in some versions
of
WM2005. But, uninstalling it from the host PC side, should be
okay.

So, what do I need to do to communicate with the device over
USB?

Thanks,
PaulH

If I have 10 WM2005 devices attached to a PC by a USB hub, how do
I
address them individually? Can ActiveSync support more than one
device
at a time?

Thanks,
Paul

Exactly my problem. So, how do I use the USB connection as a TCP/IP
network device?

All that shows is the 2 network cards I have in my system normally. I
don't see the WM2005 devices at all.

I can't use the 802.11 radio for the communications because I intend
to use this connection to modify the state of the 802.11 radio. If I
modified it in a way

I have ActiveSync v4.5.0 installed on the PC. ActiveSync on the device
appears to be pretty simple and doesn't have much in the way of
options other than setting the device to connect via BlueTooth, IR, or
USB.

I'm trying to set up a test station where a group of devices can be
attached by USB to a host PC and given a series of commands to test
the functionality of the overall system. The device would then send
the results of those commands back to the PC for validation and
logging purposes. Currently, I'm limited to configuring these tests on
each individual device and collecting the logs myself via SD-card.
