Hi, 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...
