Problem in detecting drivers

Hi

I have built a winCE image and trying to drive a WiFi USB module (for more
information: tp-link tl-wn321g which uses Ralink rt2501 chipset).

I have added the driver (rt2501usb.dll) into OS image as a MODULE (in
project.bib) and added the reg settings (project.reg).

When i power on the CEPC with WiFi module connected, it hangs after
extraction of NK.BIN. and then no response at all.

If I let winCE load and then connect the WiFi module, winCE will not
recognize it. I think it happens because driver will not load at startup if
device was not connected, maybe I'm wrong.

I tried connect another USB device (such as bluetooth or storage) before
loading winCE, but it will make winCE hang too.

So I have two problems now:
1) Why any USB devices make my OS hang during load progress?
2) My main problem (WiFi doesn't work) is because of hang at startup or I
have built a wrong driver?

any help can give me another hope...
Kind Regards;

My guess is your driver is build for x86 processor. Mini2440 is using
Samsung S3c2440A ARM9 processor, meaning you need to get from tp-link a
driver version which is compatible with ARM9.

Thanks for your attention...

But I'm sure my driver is compatible with my processor...
