unable to enumerate usb device on port 7

Binary package hint: isight-firmware-tools

Hi!

I'm using Interpid Ubuntu 8.10 amd64 - and i followed the instructons from http://www.rickycampbell.com/isight-intrepid - even did that shutdown as said there.

The problem is, since i did all those instructions, a boot message saying 'unable to enumerate usb device on port 7' in some dozen lines is hanging Ubuntu in the boot process, in around 80% of the booting times. Mostly i must disconnect everything i had in the usb connections, which situation i can't consider normal, since i didn't need to do this before. And the iSight is still not working, even after all this.

Btw, is there some way to avoid this hanging 'unable to enumerate usb device on port 7' message, and do the boot normally?

Some information i think can be considered useful:
guest@macbook:~$ md5sum /lib/firmware/isight.fw

and from Cheese:
No camera found - Please refer to the help for further information.

Another question, maybe important: should a green light turn on at the right side of the iSight len? it were turned off all the time…

Thanks! =)
