Re: Signing a driver for windows mobile 5.0 platform

Thanks for your answer.
We do need to load the driver at boot time.

Does the SDKSampleprivDeveloper certificate work on any 5.0 device?
What I did is:

1. Copy the SDKSamplePrivDeveloper.cer to Pocket PC.
2. Double click the cer file to import it into the cert database. Use
Setting->Cert to verify the cert is loaded.
3. On Desktop, type "Signtool sign /f SDKSamplePrivDeveloper.pfx
mydriver.dll"
4. Copy over the new mydriver.dll to Pocket PC.
5. Reset Pocket PC.

But the driver still doesn't get loaded. What else is missing?

Thanks.
Blues.

If your application does not have requirement to load the driver at the boot

you need to load driver at the system startup, but if you load driver
dynamically then it is not required.

We have a device driver which works fine on Pocket PC 2003 devices. The
driver is loaded at boot time. But for some reason, it doesn't work
with the windows mobile 5.0 devices. The driver is not loaded after
reset, though we can load it in our application by calling
ActivateDeviceEx().

According to this article, we have to sign the dll file.

For testing purpose, we installled the certificate
SDKSampleprivDeveloper on the pocket pc, and run SignTool to sign the
driver dll, but still it doesn't work.

I am wondering if we have to go through Mobile2Market program to make
it work.
