They are:
Brand: SEPIA
058f:6254 Alcor Micro Corp.
Brand: Belkin
0409:005a NEC Corp.
Brand: Hama
05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB

And last but not least the problem(tm) with the the AC-adapters.
Not all support "worst case" scenario. Some only provide enough power to
support 2 ports with full power and many other are only bus-powered.
The 3 hama models are exemplary for this.
One is without AC-adapter ("For Notebook").
The next is with a "half"-sized AC-adapter.
The last one has a "full"-sized AC-adapter.
The Belkin model i got supports full and the Sepia half.
