I've been having some issues with multi-USB ports. I have one connected to my iBook and at night, I'll remove it so I can use my laptop on my bed. But there are times when I'll remove the USB cable and all of a sudden, a screen pops up and says I have te restart my computer. Can anyone explain why this is happening?
Got a tip for us?

Do you mean a USB hub? What you saw was a kernel panic.
If you haven't seen it since it may have been a fluke. If it's a recurring issue, then we can do some more investigating and see what's causing the error.

It would help (assuming you're indeed talking about a hub) if you answered these questions too:
- Is the hub self-powered (it has its own power adapter / supply) or bus-powered (no separate power supply)
- What is plugged into it?

i got a mbp.. when ive plugged my phone into charge via usb and then disconnect it, it sometimes kernel panics, probably 1 out of 10 times... i think its a random thing, normally when i catch the computer unaware, ie when its just woken up, or its been inactive for a while.. i think the shock of suddenly removing a device makes it panic!!
Yeah, hub. Sorry. It has its own AC adapter. Like crazyworld, it'll happen 1 out of 10 times. Just an estimate though. Is there anything I can do to make sure it doesn't happen anymore. I have a multi-card reader, ipod wire, wireless keyboard and mouse hub, and external hard drive (which is off most of the time)
Mmm, okay. On your computer, there should be a file called panic.log. You can access it via the Console utility in your Utilities folder. I think it's in /var/log (you'll have to dig for it in the left hand side of the Console window). A crash entry will begin with the time that the kernel panic happened and then some lines about a trace back. Post the first fifty lines or so of that, starting with the very first line of the panic incident. That can help figure out if it's one specific piece of hardware doing this.
This?

No... that's not the right file, sorry, although it is interesting. The file you want is /library/logs/panic.log (sorry about the erroneous location earlier, but in any event, the file is actually called "panic.log"). This is an example of what an entry looks like -- it documents the last panic on my iBook (on 7/1/06):
