Re: How to get USB / Ethernet (NIC) working on MS Windows CE 5.0 ?

Paul,
Thanks for your comments. So, if the USB device hardware is OS
independent, why am I getting the message "Unidentified USB Device"
when I plug in the Netgear FA120 USB adapter ?
Is FA120 NOT RNDIS compatible ?
How do I verify that a USB device is RNDIS compatible ?

You have mentioned that USR5421 works on WinCE. USR5421 is a Wireless
LAN adapter. Does WinCE 5.0 support IEEE 802.11 ? I do not see the
relevant dlls in my Platform Builder 5.0.

The USB device hardware doesn't care what OS is running. As long as the
signals it gets over the USB bus are right, it doesn't even *know* what
operating system is generating them. Since the USR5421 is a RNDIS device
(it provides a standard interface), and since there is a RNDIS client driver
in Windows CE, the device works. Their specification is based on the driver
that they ship with the stick, which, as indicated, is a desktop Windows
driver...

Thanks for your response. Upon going thro' the tech. specs. for
USR5421, it listed 98SE / 2000 / ME / XP as the operating systems
supported. CE was not amomg them. Also, the connection protocol is IEEE
802.11 (as it is Wireless). We have 802.3 (wired ethernet) driver.
Reg. U2ES, it is out of production as you had pointed out, however I'm
researching U2ESC (the next generation product). I'm in the process of
researching whether it supports WinCE.

Thanks,

try to use RNDIS driver for it?

You won't have much success with non RNDIS USB Ethernet
adapters, unless the manufacturer is providing CE drivers
for it.

Don't know any supported wired USB to Ethernet adapters,
but you may want to check wireless. There is a number of
RNDIS based USB WLAN adapters (like USR5421) supported
on CE. Anyway, Google is your friend.

I need to get USB / Ethernet working on MS Windows CE 5.0.
Firstly, which device supports it ?
I was trying to use NETGEAR FA120. According to the tech. manual, Win
CE is NOT supported.

We are using Windows CE ver. 5.0 in our product and I have been trying
to get the RNDIS working; but have not been successful so far.
I have a NETGEAR Model FA120 USB / Ethernet adapter (NIC) plugged into
the USB port of our product running WinCE 5.0.

Is NETGEAR FA120 supported on Windows CE ? Their spec. does not list
Win CE (it lists 98, ME, 2000 and XP)

As soon as I plug in the NETGEAR NIC, I get the message 'Unidentified
USB Device' on my application console.
When I type the Driver name 'USB8023.DLL', I get the message :

I believe RNDISMP.DLL and USB8023.DLL are part of WinCE 5.0. How can I
get it working so that the driver of the USB / Ethernet NIC plugged
into the USB port is recognized ?
We do not have the source code for USB8023.DLL (part of Microsoft
library).

The USB port itself on our product works as plugging a USB flash drive
works.
