Good news! I managed to get the Targus hub info using dmesg (not sure why it worked better this time) and also dug out vendor/product info for the 3 devices I've tested.

Also, I have bid on 2 more cheap dongles to test. If the ebay price stays low I'll go ahead and buy them, test and provide further data.

Update: I won a Netgear EA101C USB Wired Ethernet Adapter for 99 cents plus $4.80 in shipping.
