When I'm trying to do "one touch provisioning" on my Intel AMT station through USB key (PSK), I'm getting such output:
USB Key Local Provisioning file is being processed...
Do not power down system until processing is complete.
Reading USB key provisioning file...
2220-USB Key Local Provisioning file has mismatch version
ME BIOS Extention module execution has halted.
Update BIOS or Management Engine firmware if problem persists.
I'm using Intel AMT SCS 188.8.131.52
PC (HP dc7800sS8) I'm trying to configure has Intel AMT ME BIOS Extention v3.0.2.0004
Oh, when I manually generate PSK key and type it at Intel ME all works fine.
There was problem with my pen. I was using 4GB (Fat32 partition). It started working when I have changed it to 1GB (Fat partition).
