China KJ-71-174V1.1

This is not actually a USB 2.0 High Speed hub.. despite claiming as so to the host OS (and perhaps also the end user, if it has been labeled as such).

The hub IC has been epoxied to the board and is thus not easily identifiable. The vendor and device ID for the thing

"KJ-71-174V1.1" and "20101125" is silkscreened on the board.
 * This entry has been named based on silkscreened text on the PCB. There is no model or manufacturer designation on the casing or label.

"4 Port", "USB HUB", "S/N:08-240091AA0171Z", the CE and FCC logos, and "MADE IN CHINA" is printed on the label affixed to the bottom of the unit.
