What is the BBU3900 USB Driver?

The BBU3900 USB driver is a piece of software that allows a Windows-based PC to communicate with the BBU3900’s internal maintenance port via a USB connection. Unlike network-based connections (e.g., via SSH or Telnet over Ethernet), the USB port on the BBU3900's main control board (typically the UMPT or WMPT board) provides a direct, out-of-band management channel. bbu3900 USB driver — write-up Alternative Source (Use
