So...got a new model laptop in the district. Latitude 5420. Downloaded the Platform Pack and rebuilt all of our deployment packages (console and USB). I have about 12 application packs as part of the deployment as well. I fire up a new 5420, jump in the BIOS and change from RAID to AHCI, reboot to USB drive. It will run through the imaging process, joins domain, installs a few of the application packages, but then just stops. Seems like it's the last part of the process (application packs). Always stops after the 4th (?) app pack. It seemed like maybe a chrome app pack issue, but I edited the .xml file and changed the position of the chrome installer (4th to 12th). Still stops installing after the same app pack. Then it will throw an Unrecognized USB device error continuously. I've tried 4 different flash drives and always does the same thing. I have the latest platform pack for the 5420 (I haven't tried these flash drives on another model yet, but I suddenly have 50 of these 5420's NIB to image asap), but also noticed when I run Windows Update (after imaging and after the app pack installs fail) there are a number of driver updates waiting. Any input would be appreciated. Apologize if I'm missing any important info.
