In The Other Corner, The Multi-TT: LinXcel USB 2.0 Hub

The LinXcel device was sent to us by Cypress Semiconductor. With several TTs, it should be able to seamlessly integrate any connected USB 1.1 device into the USB 2.0 upstream.

The first thing that catches your eye is the hub's size. Despite having four ports, it is smaller than a pack of cigarettes. The only thing that disappointed us was the connection between the upstream port and the system, which LinXcel realized with a proprietary cable.

According to the information on the package, the hub supports devices with up to 100 mA per port when it is not connected to any voltage source. If you use the adapter, it supports 500 mA as specified.

  • 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.
