I didn't know where else to ask this. What could have gone wrong with my USB hub for it to stop data and power transmission after I plugged in the auxiliary power adapter that it came with?
I have used this hub for about 7 months now without it's power adapter, it doesn't really have a brand, just 7 Port USB 2.0 Hub, sort of flat and silver looking. The DC5V light used to come on from the computer power alone, but after plugging in it's 5V 0.5A wall-wart power adapter, the hub ceased to function. At first my mouse was blinking red to signify insufficient power, and now nothing lights up, nothing gets power, and no data passes through the hub.
I thought at first that I may have opened the poly-fuse in the computer's USB port, so I changed ports with all the devices still plugged in, same problem. I unplugged it again, then unplugged every device and tried yet another port on the back of my computer, same problem there. So the problem isn't power surge, right? I checked my computer's event log, no mention of USB problems.
If it isn't power surge, I don't know what the problem is, especially since it stayed cold and made it through the last 7 months flawlessly. It's like the hub won't even turn on without the wall-wart, even so, no power or data transfer occurs with it plugged in.
