Re: DEVICE_ID broken on HP iPaq 210 models?

Tech-Archive recommends: Fix windows errors by optimizing your registry

On all Windows Mobile 5.0 and later devices you should use GetDeviceUniqueId. See the SDK documentation for usage.

Hi

We use the DEVICE_ID structure returned by IOCTL_HAL_GET_DEVICEID to get a
unique device ID for use in our licensing scheme for our Pocket PC software.

We have noticed though that the newly released HP iPaq 210 models don’t
appear to return unique device data in the DEVICE_ID struct.

The PresetID bytes are the null terminated Unicode string “PocketPC”.

The PlatformID bytes are the null terminated ansi string “HPIPAQ210_24337”.

Has anyone else noticed this?

If so is there an alternative mechanism to get a unique device ID on HP 210
models?

Cheers
