Hi,
This is a breakout board that was made specifically for the measuring of current consumption of USB 1.1 and USB 2.0 devices. The board was tested with several devices and, in any case, no noticeable performance loss was observed with this board between the host PC and the device. I'm currently selling a few modules on eBay:

Only high quality materials were used, namely the base material is FR408 substrate and the copper has an ENIG finishing. Although the board is not certified, all the connectors were certified by USB-IF.
I'll make a discount for the EEVblog forum users: $50 for the board and $8 for the shipping, is the board is purchased here (outside eBay). As usual, I only accept PayPal. Please, feel free to send me a PM.
Kind regards, Samuel Lourenço
