Another attempt to make DIY iPod charger
I found a Polar USB hub with AC adaptor. Shorted data+ and data- pins of one USB port after isolating them from the hub's chip. This time, the USB hub is being powered ONLY and directly from its AC adaptor, rather than using an AC to USB adaptor. It works, including hot-plugging. SO the problem might be the AC to USB adoptor. -- @~@ Might, Courage, Vision, SINCERITY. / v \ Simplicity is Beauty!

Another attempt to make DIY iPod charger
This time, the USB hub is being powered ONLY and directly from its AC
adaptor, rather than using an AC to USB adaptor. It works, including hot-plugging. SO the problem might be the AC to USB adoptor. I went back to the other USB hub, chopped the data+ and data- pins at the input USB port that's connected to the AC-to-USB adaptor. The charging instantly started working, including hot-plugging. -- @~@ Might, Courage, Vision, SINCERITY. / v \ Simplicity is Beauty!
