GetDeviceUniqueID not working on some smartphones...

GetDeviceUniqueID is returning the exact same "unique" ID on 3
smartphone mobile 5 devices that I'm currently working on.  The same
code, taken straight from getdeviceuniqueid.h, works fine on CE mobile
5 devices.  Has anyone had this problem?  Thanks.

It looks like the guy's who put together the BSP's that you have for WM did
not correctly implement the kernel IOCTL_HAL_GET_HWENTROPY and
IOCTL_HALL_GET_DEVICEID calls.  They probably took one of the sample BSP's
and just ported them.  On devices with these calls implemented correctly
GetDeviceUniqueID should return a "unique" ID.

I am having the same problem with the PPC-6700 by Sprint.  All of the
Pocket PC phones are returning the same "unique" ID.

I've check with MS on this one, they know about it and are going about
getting a fix, but it won't apply to devices that have already been
shipped :-(

There is nothing noble in being superior to another. True nobility
arises from being superior to one's past self.
