Where were you a week ago?  :)

That would have made things easier.   I was successful in splicing into a 5v line and powering my hub though.

vertygo:
Haha sorry.. but honestly, I bet you feel much more accomplished splicing a wire than entering a credit card number ;)

Plus, it always impresses the laaadies..

"Look Honey, I spliced this wire to the USB hub and it's powering up!"

"Oh snookums, that makes me want to tear your clothes off right now!"

or something like that (it's 2:30 AM, gimme a break)

Cheers!

Not so much a big a deal these days but it is handy, a few years back I think VIA had a chipset that if you tried to draw the full 500ma direct from the port the USB ports on the machine shutdown and would not start working again until you reboot.

I have a monitor with a USB hub. When it's hooked up to a PIII that's now in an arcade cabinet, it draws enough power at start up that the machine can't POST. If I hook up the hub after the PC is booted, it runs.  I'm not sure if it's the hub that's broken or a weak power supply in the PC, but obviously I don't use that combo anymore.

My PSU powers the USB ports even when the main PC is powered off.

Would that be a better solution?

Also you get a 5v plugs to USB 1.1 when you buy an external drive.  I plugged one of these into my Belkin 4 port hub and it worked fine, well until I powered off the laptop.  ;)
