I'm using the GL850 http://www.qobuz.com/info/IMG/pd... with an application I'm developing. My application is 4 usb 1.1 devices using the v-usb library. Those 4 usb devices connect to the GL850 and there are a few issues all that are fixed by adding a external hub.

 

computer--hub---GL850

 

Symptoms such as the computer will not boot up (won't pass bios) with the GL850 connect directly to the usb port. This was solved by adding a hub as shown above. The GL850 is a low power hub that also has a built in 5 and 3.3 volt regulator. I'm powering the GL850 from the computer's usb port at the moment but I plan to try using an external power source. I hopping that will fix my issues but I don't know where else to look.

 

I added the schematic for reference.
