Standard Hub With One TT: DLink DUB-H4

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

The DUB-H4 is a common model for sale in many countries. It sports a total of four ports and is listed as being USB 1.1 compatible - only, however, by virtue of one single transaction translator.

There are many situations in which you may prefer to use the hub without any power: when traveling, or when you don't have to time plug it into the wall socket. Unfortunately, the D-Link website doesn't say how much power the hub puts out in those circumstances. If you use the adapter that comes with the hub, it will produce 500 mA per port.

It measures a fairly compact 10x6x2.5 cm. We were pleased to see that the uplink port to the USB controller was implemented with a standard cable - proprietary solutions tend to be more common. Nor shall we ignore the length of the connecting cable: 1.5 meters. That's long enough to hook the hub up to not just a laptop, but also to the tower PC hulking under your desk.

    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.
