Hi Poller, these look like COM based errors.
I recently did a TechEd demo with an Intermec Device - all went fine.
Hard to see exactly what's the source of your problem but some points to try:
1) try that the reader, and sample apps on the device work. - system settings->intermec - look at settings here, in the Readers section.
2) grab the latest rfid providers (intermec) and see what you've got -
Grab the 2nd link on the page - as this has a mobile provider that uses the latest intermec apis to talk to the device (I wrote my own provider)
