What is important – the modules for input devices mouse, keyboard and joystick and printers are fully working ready for every day use and transparent to DOS so everything works like normal legacy devices. Possible reasons for transfer errors include: If it seems persistent, following reasons are possible: It is fine that it supports hot-plugging not partially but completely and you can change one flashdisk to another. It implements only read access, no write support yet. Most USB storage devices have some activity light revealing that a data transfer is running.

This also makes filesystem flaws see  worse. Workarounds worth to try: The lowlevel part is called sbp2aspi and the highlevel nj32disk.
