Like the subject says I can not use a thumb drive on my OfficeJet Pro 7740. I have reformatted it to fat32, no go. ExFat, no go. NTFS no go. FAT (default) no go. It is an older thumb drive but it works on my desktop computer so I'm pretty sure the thumb drive is still good.

Welcome to the HP support community.
I understand you are unable to connect a thumb drive to the printer USB port, I am glad to assist you.
The printer does not support encrypted USB flash drives.
Follow the steps mentioned on page number 32 in this user guide to print from a flash driver:- Click here
Keep me posted.
If this helps, please mark the public post as an accepted solution so that it benefits several others.
Cheers.
