The motherboard does not receive usb power, this device helps to solve the problem, due to the external power on the volume of the same usb, very helped to solve the problem on the system unit, be sure to order even so that there were no more such cases, sent quickly the seller i recommend the thing clear, But there is a small minus plug 3.5 usb power does not go to the end, but this uncritical operation does not interfere.
The plug (charging as I understood) is not completely included in the adapter itself. Light bulbs and without switches (position on i) are lit if you insert a USB cord. switch at least one on the I-on the sides light up the bulb.
Excellent and Reliable Seller, Highly Recommended.
Shipping, 38 days to Greece, but the Packets it's OK and Everything is fine.
Excellent item, built with excellent material, Excellent quality/price ratio.
I Test it A little and looking to Working Perfect...
Thank you very much.
