These errors occured with the webcam 06f8:3009, but I do not know
exactly how. I thought about a speed problem. May be, when the webcam
cannot treat quickly enough the requests, either it returns errors or
it crashes. An other cause could be a bug in the ohci_hcd, but I do not
looked at it. The delay was just a test and it fixed the problem. That
is all the user wanted...
