Re: ADM851X USB-LAN-Adapter driver

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

If it's not the adapter, it's the USB host hardware. There are undoubtedly
timing differences in when power is applied, etc. on Windows CE vs. desktop
Windows. You'll have to figure out what's different and to which the
adapter is, apparently, sensitive. Again, sniffing the USB packets would be
helpful. This is *NOT* going to be a problem where someone is going to pipe
in and say, "Set this registry entry to 10 instead of 5 and everything will
work.", or at least I'd be shocked if that were the case.

The simple, general things that you can do are: make sure that you have all
of the QFEs for your version of Windows CE installed and built into the OS,
verify that you have the latest available version of the adapter driver
source (and ask for a CE5-compatible driver, for goodness sake!), turn on
all debugging messages in the driver (and add more, where it makes sense),
and figure out what's different in the two OS versions.

It looks to me like your adapter might not be working correctly. It
would
be worthwhile to try another one of the same type, if you haven't
already.

If the hardware is eliminated and you are running on the same board
that the
Windows CE 4.2 driver worked with, then there's something wrong with
your
driver. I don't have any insight as to what, specifically, would be
wrong.
Are those last couple of messages generated by you or the USB host
controller driver? I'd start with breakpoints where the transfers are
supposed to occur and see which one(s) fail and why. Your USB sniffer
will
probably help here, too.

Hi Paul,

Thanks for reply.
These are the debug messages which we get on Hyper terminal after
connecting adapter.

It will stop here at this stage, Please let me know what I need to
change, I have increased USB host controller memory.

Thanks,
Percy

Hi ALL,

I'm working on ADM851XUSB-LAN-Adapterdriver, PXA255, WinCE 5.0.
I'm porting this driver from 4.2 to 5.0 with same Hardware.
Device will detect Adapter, but it will hang some where, and we
can't
browse.
where may be the fault, please help me with suggestions.

Thanks

I totally agree with Paul.
I have faced this problem earlier and in your case as per the messages
it clearly seams
to be some problem with the hardware.
Try with another hardware sample.

Hi Mike,

USB-LAN-Adapter is working fine on PC, Win XP. Can you help me out
with how to take this issue forward.

Thanks,
Percy
