There are a handful of off the shelf micro-controllers that control USB devices and chances are we will find one that works through the process of elimination. Please try installing this driver and let me know if it works.

Once the right, new file system is configured, you can store the files on the USB stick again and try to connect with the target device again.Hub (EHCI Root Hub Simulation) 0xfa000000 with 6 ports There you can temporarily store the files locally and then reformat the stick. In either case, the solution is to plug the USB stick into another device that offers the necessary support. While Mac computers only partially support the Microsoft format NTFS ( New Technology File System) if at all, for example, Windows systems without additional software are not compatible with the Apple format HFS+ ( Hierarchical File System) or its successor APFS ( Apple File System). If this support is not available, it’s highly likely that the USB drive will not be recognized or its content will not be able to be opened. The operating system of the device with which the stick is connected has to support this file system in order to access the stick (reading and writing access).

Like all storage media, a USB stick needs to have its own file system so that it can be used to store files.
