Overview

This hub presents itself to the host system as two 0409:005a devices

.. it is somewhat light (80g) for a hub of this size.

• View of the device's board on bitcointalk.org

"MADE IN CHINA" and "PU20114-7G0A" is silkscreened on the board.

The manufacturer (seems to be a Sunrich Technology U-340...)

is almost certainly the same as the Rosewill RHUB-210.

The power adapter included with the hub is an unbranded

JD-050-020 (100-240VAC ~ 50/60Hz -> 5VDC 2.0A).
