USB Technology: Multi-TT Hub Goes Head-to-Head With Single-TT

[Guest]

A USB hub is a must-have if you want to run several external devices. However, in order to use USB 2.0 and USB 1.1 devices at the same time, your hub will need a so-called transaction translator - or TT for short - to handle the different data flows. In our test, a classic hub with only one TT squares off against an advanced model with multiple TTs.

I am having a really hard time resolving this issue on a brand new Asus desktop machine with the Asus motherboard P8H61-MX. It seems that Asus have cut a corner or two and only included a single TT setup on the motherboard which has 6 inbuilt USB ports. I am having real difficulty finding a PCI express USB card here in the UK which actually has a built in Multi TT setup. My Novation NIO 2|4 soundcard and my Vestax VCI-100 midi controller fail to function without multi TT, and if anyone has any advice it would be appreciated.
