I got a new motherboard with USB3 on it. All seemed fine and I started using an 8 gig memory stick with it and a HD TV tuner in the USB3 ports. some days down the track the memory stick died. The computer recognizes it from the computer end but brings up " please insert disk " when you try to access it.Otherwise unusable.

Some days later my HD TV stick stopped functioning. I opened it up to find a fried transistor in it [ literally blown apart]. This is a symptom of too much power.

I checked out the Power Supply and all tests fine. A mild surge on start up but all appears to be fine. I checked the specs for USB3 and found it delivers around 1.6 > 1.8 amps. I don't know what the two sticks that died draw but I'm presuming they're low powered.

USB3 is so designed so it can run external Hard drives and other higher powered devices, without frying your board by drawing too much power. I'm presuming the reverse is true for the low power devices as I know that low power devices such as cameras and guitar FX pedals don't like too much in the way of ampage.

Any thoughts about this people?
