Disable AS but allow TCP over USB

Hallo,
we are developing app where we need to disable Active Sync due to security
issues - when AS is allowed, anyone can connect PC to device and access it's
file system, registry, ...

My question is, whether it is possible to disable only some of AS
functionality - i would like to use TCP/IP connection over USB cable provided
by ActiveSync.
(Or is there any other way to establish TCP/IP connection over USB without
ActiveSync?)

Thank you.
 
Hi,

I don't think this is possible. ActiveSync provides the TCP/IP transport,
not the other way around.

I think you should consider using either a wired or WiFi network connection,
Bluetooth, or perhaps IrDa.

There is no way to control/disable AS functions.
Usually the cradle will have a RJ45 connection, which will enable a
TCP/IP connection to your network.
The handheld then can establish a DHCP IP address or you can also set
a static IP to access the network. Proxy/VPN can enable you to have
better security.

Bluetooth/IrDA is Serial connections (RS232), to enable TCP/IP over
these you will have to use AS to connect to your machine for debugging/
deploying.
WiFi is the possibility to have TCP/IP but then need of USB as you had
mentioned is ruled out.

Can you please tell us the need specifically, will you be doing
development with this setup? or do you need this setup in your end-
client environment?

I use AS when developing (for debugging/testing), but i need to disable it
in end-client environment. We use TCP/IP just for data synchronization.
 
There was a big discussion of this sort of thing recently in another group:

Basically, the answer is no, you can't do that. You have to install
ActiveSync on the PC in order to get a suitable driver for the USB device
that you're trying to plug in. You could try a generic USB RNDIS driver, I
guess, but I suspect that there's enough difference between the AS driver
and the generic USB RNDIS that it won't work.
