https://bitcointalk.org/index.php?topic=364290.0I did something extremely stupid the other day. I, in a jumble of wires, plugged my 12v BFL Jalapeno power into my 5v D-Link Hub...ooops! Within a second the redfury/hub (not sure which) began to smoke which is where I hastily unplugged it.
The USB Hub works fine still, but the Redfury now comes up on windows as "usb device has malfunctioned and cannot be used" I also had a lil 333MH/s erupter which also blew up but I don't care much about that, that one doesn't even read as being plugged in.
Is it time to bin the redfury or is there any hope at all. I don't really know anything about circuit board electronics, could a pencil mod save me if it's blown the resistor or anything like that?
