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

Hi,

as voidcoder mentioned, it is not because a usb 2 ethernet uses the kawasaki
chipset that it is rndis compatible as well.

You mention the tests with the NETGEAR FA120. According to the internet,
that unit uses the ASIX chipset.

As I told already on this newsgroup, you can find drivers for windows CE 5.0
for their chipset.

Just, no version for the hitachi cpu group. (SH3 SH4) Maybe, if you contact
them, they can deliver you a CE driver for SH4. After all, it should just be
a recompilation with other CPU settings.
I tried to contact them and asked them for devices using their chipset. I
never got any response. I hope you have better luck.

regards,

Luc

Hi voidcoder, Luc Cool :
Your suggestions were very helpful.

I plugged in the NETGEAR FA120 into my desktop PC running Windows XP
and it is operational.
In Device Manager->Properties->Details, upon selecting 'Instance ID',
the following is displayed :
USB\VID-0846&PID-1040\5&9DA6B9A&0&2
I could not identify any Class or Interface information.

The above VID and PID are displayed in my Platform Builder 'Debug'
window upon plugging in the FA120 into the USB port of our WinCE
product running 5.0 (debug log attached) :

From the above log, the USB device (FA120) is recognized :
Dev.idVendor = 0x0846 (NETGEAR), Dev.idProduct = 0x1040 (FA120),
Dev.bDeviceClass = 0x02, Dev.bDeviceSubClass = 0x00,
Dev.bDeviceProtocol = 0x00

Why is Subclass = 0x00 and DeviceProtocol = 0x00 ?

As per your suggestion, as our product running WinCE is the USB Host
and the FA120 is the Remote NDIS device, I have deleted USB
Function->USB Function Clients->RNDIS Function Client from the OS
Design.

I verified Catalog->Core OS services->Communications Services and
Networking->Networking Local Area Network (LAN)->Wired Local Area
Network (802.3, 802.5)->All the paths for the drivers and RNDIS, NDIS
miniport drivers are listed.

I have removed the RNDIS related registry settings (which I had added
earlier) from platform.reg

I checked my WinCE500\PLATFORM\xx\xx.bat (xx=platform) and BSP_NORNDIS
is NOT defined.

I have verified my ................/SH4_Debug/ directory and I have ALL
the relevant .dlls :
rndisfn.dll, rndismp.dll, usb8023.dll, usbd.dll, usbdisk6.dll,
usbprn.dll, usbhid.dll, USBMSC.dll, USBModem.dll
I called Netgear and Linksys and both could NOT confirm that Netgear
EA101 and Linksys USB100T are RNDIS-compatible. Their on-line technical
specifications do not mention RNDIS at all!

If you are 100% sure that the RNDIS-compatibility is my root problem, I
shall buy EA101 and "try it out" as Luc has pointed out.

Thanks very much,

Hi voidcoder,

i have to agree with you. One thing that comes in my mind is the
question
why people using chipsets in their devices might want to reinvent the
wheel?

The chipset is the only reference we have for the moment to assume that
a
USB 2 ethernet device "could be" rndis compatible. I recently contacted
US
robotics support to ask if their USR5423 was still RNDIS compatible and
got
the following answer:

We believe it still should be compatible , however the USR5421 is not
tested
on Windows CE and nor do we have the opportunity to test this.

The USR5423 has an Atheros chipset and if this is supported by Windows
CE
then it should work.

So, the chipset is different from the USR5421... and the chipset company
doesn't mention the word RNDIS once in their specifications....

This only leaves "trying things out" as a option. Posting the results in
this newsgroup might help against reinventions of the wheel.

But DES is looking for a wired device. So, USR is not in the game.

regards,

Luc

As I understand, it is not really a rule. Even the chipset
is described as RNDIS compatible (what I think means that
the chipset manufacturer is providing ready to use RNDIS
enabled firmware or some sort of RNDIS SDK for their chipset),
the final adapter manufacturer may choice to not use this
feature in their device.

Hi,

Thanks Voidcoder for the info about the US Robotics chipset.

As Paul explains, if the chipset is RNDIS compatible, it should work
with
the CE provided driver.

I searched the web, and found a list of adapters that are supposed
to
use
the Kawasaki chipset:

Kawasaki LSI KL5KUSB101B-based USB adapters:

3Com 3c19250
3Com 3c460 HomeConnect
AboCom Systems URE450 Ethernet
ADS Technologies USB-10BT
Aox USB101
Asante USB to Ethernet
ATen DSB-650C
ATen UC10T
Corega USB-T
D-Link DSB-650C
Entrega NET-USB-E45
I/O Data USB-ET/T
Jaton USB XpressNet
Kawasaki USB101
Kingston Ethernet
Linksys USB10T

Netgear EA101
Peracom USB
Portgear Ethernet
Portsmith Express Ethernet
Psion Dacom Gold Port Ethernet
Shark Pocket Adapter
Silicom U2E
SMC 2102USB
SMC 2104USB

it is kind of strange the Silicom U2E is in the list, while I am
sure it
should be the U2ES.

The list might be incomplete. However, it is a starting point.

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,
DES

Is NETGEAR FA120 RNDIS class device? If not, why do you
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.
