Can the Neo charge and use devices on a USB hub at the same time?
It’s entirely a cabling problem. The neo essentially has two ports in one – there is the mini-AB port, which is missing the 5V line, and the 5V charging line. When the Neo is plugged into one of the the outputs of a USB hub, the 5V line is used to charge the battery. The 5V line is not otherwise used in the neo. To use peripheral devices plugged into a hub, the Neo must be plugged into the input of a powered hub, that is capable of working without 5V input (the Belkin Tetrahub for example will not recognise a host without it). To use peripheral devices and charge at the same time, you need to make up a special cable, that plugs into the output of a powered hub – to pick up the charge current, and into the input of a powered hub at the same time – to act as a USB host. These cables are wired together for 5V and 0V, but only the input cable has the data pins wired. In some cases (the belkin hub mentioned above) this will also allow the hub to recognise the neo as a host, when it would no
