Unfortunately this little hub just didn't work for my purposes, even though the form factor was ideal. I'm trying to use several devices (Insteon 2448A7, White and Aeon Labs DSA02203-ZWUS Z-Wave Z-Stick Series 2 USB Dongle Portable USB Adapter) that implement the serial protocol over Virtual Comm Port interfaces (one with FTDI and one with silicon labs). If I only have one of these devices connected, it works. However, when I plug both in, they don't work. There seems to be a sync issue when both devices are connected to a hub. Serial connections to these devices return garbage when both are connected. [EDIT] This could be a power supply issue as there are other reviews that suggest power is not properly routed through all devices.
