Prusa Mini + FW 5.1.2+13478 NO USB constantly

Any time it try to transfer data over Prusa Connect, or Prusa Link the USB device will unmount and show as NO USB on the Mini's screen. The only resolution for this is to turn the printer off, take the USB Stick out connect it to a Linux PC so that I can mount / unmount the disk and then reconnect it. If I try to put the USB Stick into a Windows computer, the Insert USB Noise happens but no Disk is detected.

I have tried with several different Makes / models of USB Stick

I am only using a 4GB partition in FAT32 format on these USB Drives.
There are no sub folders on the drives, just the few bgcode files I am using at the time as well as 1 copy of the latest firmware.

Anyone else seeing issues like this? It only started happening after the last 2 firmware updates (when they merged the code with the XL / MK4

Try to do factory reset of the printer and format pendrive in PC using full format (no quick).

See my GitHub and printables.com for some 3d stuff that you may like.

I have completed both of these tasks and will do testing to verify that it works now. I notice one thing right away, the latency in moving the encoder wheel is gone, and the interface is MUCH snappier.

I just ran some tests and it still does the same thing, try to send a print to it, the file starts to send over and then The printer disconnects from the network and it says NO USB

Is the network connection wired or wireless? If wireless, try a different WiFi module, or try wired.

Regards,

I am using a wired connection, I have tried several Wireless modules, and the best I have been able to do on them has just been too slow for my liking so I stick with a hardwired option.
