See BU-86x (USB HID).
The user manual references a "BU-82x" which may or may not be a typo. The sigrok support was tested with a BU-86x cable.
Protocol
One outgoing HID report initiates the transmission of another reading (think serial-dmm packet request). The reading is received in three incoming HID reports. The 24 bytes of payload data carry bitmaps for LCD segments. The vendor provides the protocol description in the download area.
