Linksys USB2HUB4

USB 2.0 4-Port Hub - ProConnect series

The Linksys support page states there is one version with information available (v2.0), but I don't know if there are actually multiple revisions of this device. The device used to populate this entry has a S/N of AC1A13802162.
 * The device pictured in Linksys's User Guide (copyright year is 2002) has a strip with ProConnect USB 4-Port Hub USB 2.0 or something on it.. this is not on my device.

"M01-UH402-A10" is silkscreened on the board.
 * This would seem to be an AboCom UH402.

The power adapter included with the device may be a Honor Electronic ADS-0521PCD (100-240VAC ~ 50/60Hz, 0.3A max. -> 5VDC 2.1A).
