USB Transfer Modes
This MiniStation transfers files in either UASP (USB Attached SCSI Protocol) mode or BOT (Bulk Only Transport) mode, but a computer equipped with one of the target CPUs may not support USB drives in UASP mode. By using USB Mode Manager to change the MiniStation’s USB transfer mode to BOT mode, the MiniStation will be compatible with computers running the target CPUs. USB Mode Manager will set the MiniStation to one of the following modes.
Auto Mode (Default)
The MiniStation will be set to this mode when you launch USB Mode Manager on a computer with a CPU other than the target ones.In this mode, the MiniStation will switch between UASP mode and BOT mode automatically for best performance when transferring files.
BOT Mode
The MiniStation will be set to this mode when you launch USB Mode Manager on a computer with one of the target CPUs.In this mode, the MiniStation will always transfer files in BOT mode.

Notes:
• On a computer with one of the target AMD CPUs, the USB transfer mode cannot be changed to auto mode. On a computer with a CPU other than the target AMD ones, the USB transfer mode cannot be changed to BOT mode.
• It is recommended to backup any data on the MiniStation before changing the USB transfer mode.
• If you change the USB transfer mode to BOT mode, the transfer speed may become slow.
• If you have any questions, please contact Buffalo technical support.
