This is an extensions to this thread. I started a new thread because after an accidently discovery, I discovered something interesting. Just then I plugged the hub in to the computer (without the external power cord connected) and it worked fine, plugged my Bluetooth adapter in and that was recognised, plugged in the iPod and same story! I thought that maybe something a system update had pulled down recently fixed the issue but on a hunch I unplugged everything, hooked it up to power and plugged it back in and the error is back! Unplugged it all, removed the power and plugged it in again, same error.

I know nothing about hardware or electrical stuff or anything but here's my theory. I have two USB busses (is this right?) as I have 4 USB ports on the back of my computer and 2 on the front. The back ones work fine, the front ones did too until I plugged the hub in with external power. Could it perhaps be overloading the bus its connected to which is shutting itself down as a safeguard? I haven't rebooted to see if it works after that yet but it sounds possible to me. The weird thing is that the hub works fine (with power) under Knoppix...

Does this mean faulty hardware as in the AC adapter that came with the hub isn't scaling the power input down enough and it's shorting out the front USB bus?

Any advice would be appreciated by someone who has a better idea of what they're talking about than me

Thanks

It would likely mean the USB ports in the front of the tower have the wires out of order in the motherboard's pin slots. Which would mean that they are already "overloaded" and power is there on many pins when it really probably should not be, or at least incorrect voltages. It may be just the return pin getting current, you never know.
But I would check that before anything else.

That doesn't mean it is impossible to get a faulty AC adapter, but it is highly unlikely.

Thanks for the tip, I did have my case apart and it was suggested by someone else I talked to that I might have knocked something along those lines while I was playing. I am at a course for work this week and this is the first time I've had time to check a computer but when I get home it'll be the first thing I do after a nice long sleep

Thanks again
