I have a new Dell Precision 7750 Laptop that will not properly enumerate the cards in a PXIe-1062Q Chassis via Thunderbolt. The Chassis and cards function when connected to a two year old Dell Latitude 7490. The Chassis is detected fine without any cards inserted. When the Cards are inserted the SMBbus Controller (Chassis) has issues. As one might expect NI Max is a mess as well I have seen some reports of similar issues but no solutions. It seems to be a driver issue with new Thunderbolt Hardware / Security?

I found a similar case that appears to have been solved by the MXIe BIOS Compatibility Software. Please try that. If it still doesn't work, check the Windows Event Log for messages from nipxirfk and nipximxk and post anything you find. This may help identify more details about the problem.

I had the same problem with a PXIe-1083 rack, and it has been fixed with the MXIe BIOS Compatibility Software. Thank you
