Activesync device question

[Kid]

Hi

I've tried two Windows Mobile Phone, use Activesync USB connection, I found
they
catch different PC Windows driver :

(1) Phone #1 become a Windows CE USB device, use PC driver wceusbsh.inf and
wceusbsh.sys

(2) Phone #2 become a Network device, use PC driver WceRndis.inf and
usb8023y.sys and rndismpy.sys.

These two drivers are all provided by Microsoft , and both of they can use
Activesync 4.5 .

Do you know what's the difference of these two drivers and product design ?

Thank you very much.

the first phone expose itself as an USB serial device, the second exposes
itself as an USB network device

The phones are probably either running different versions of Windows Mobile
(2003 and earlier acted like serial-over-USB devices, while Windows Mobile 5
and 6 act like RNDIS devices, by default). If they are the same model and
version of phone, there's a setting in the ActiveSync program *on the
phone*, which allows, for compatibility purposes, the phone to be switched
from Serial to RNDIS and back. It's typically named Advanced Network
Functionality or something of that sort. It's there because, when the phone
acts like a network card (RNDIS mode), it's subject to services running on
the PC which might tend to prevent ActiveSync from working (firewalls, VPN
software, etc.)
