Can you get any other drive to be recognized by the 4802? (ie. try another thumb drive formatted with NTFS to test).
Can also try Removing the Roku Media Player(RMP), Restarting the Roku device, and then Reinstalling the RMP channel/app. (Remove, Restart, Reinstall).
Sometimes just removing the drive, restarting the Roku device, and then reinserting the drive will help RMP to rescan the files.
Thank you so much for your response,
Yes, I have tried other USB devices in the 4802 port, same result.
I have also tried the other two suggestions, rebooting and deleting the RMP exactly as you have suggested but again, same result. Don't know what to do next. I have an older Roku Ultra 46?? device that I tried it on, with the same roku software version, with the same result. If I knew how to go back to an older software version on the 4802 I would try that, but I don't see a way of doing that.
Any suggestions? Please?
Ran a couple different USB flash drives formatted to both NTFS and FAT32 on the Ultra 4660 (OS 12.5 build 4178-46) and worked fine. Met with the new message re: allowing the device access to the USB).
Could certainly be the 4178-C2 build if happening across different flash drives and your previous one was working prior to the build update.
Does formatting another flash drive to FAT32 offer same results as the NTFS?
That is a good question. Have not tried FAT32. Will try it today and get back to you.
Just tried a FAT32 usb flash drive. Nope. Exactly the same result. I guess that makes me even more convinced it is the software update, but willing to try other ideas. Makes me wonder if Roku is the way to go any more. Sure don't get much support from them.
There was an early issue some users reported with mp4 when 12.5 initially released, but those seemed to have been addressed with a subsequent build. (essentially, some mp4 were not being recognized by RMP). Therefore, if all your files were in that particular mp4 container, they would not be recognized and RMP would see an empty flash drive (or drive with incompatible formats), thus prompting that error/help message.
I did see some developer update somewhere that wma format has now been officially dropped so they would not be seen at all anymore.

It does sound like though that your Roku device is simply failing to detect a USB presence when you insert the flash drive. (could indicate either software or hardware issue).
I think I would try the Factory Reset option to see if that helps clear out any corruption. Press and hold Reset button for 30+ seconds. (just make sure you have a working physical Roku remote before performing a factory reset).
After performing the Factory Reset, if USB detection is still a no-go, I would see if RMP can detect/play movies through a DLNA server. (ie. if your router is so equipped, you can place the USB in its USB 2.0 or USB 3.0 port and enable the DLNA server or UPnP and see if RMP sees and plays the videos). At least then can help narrow issue if RMP issue.
You could also try using Plex or Jellyfin installed on a laptop and try the same thing. Run it as a DLNA server and see if RMP recognizes the DLNA server and plays the videos.

I just inserted empty USB drives (formatted to both NTSF and FAT32.) I was greeted with the message box "Allow access to External Media" when I was on the Home Screen. The drive does not show up at all when I go to RMP. (no message regarding the help on setting up DLNA server). I usually only get that message with RMP loses communication with my router mounted USB drives.
Having a bit of difficulty creating the issue you are seeing.
If after running through the above steps, can you try just placing a single .mkv and single .mp4 (smaller video files) on the flash drive formatted to NTSF and see if RMP sees either of them. And also, are you not receiving the message re: Allow access to External Media" when you are inserting the drive into the Roku device?
