You should be able to modify the usb-storage driver right now to possibly fix this.

Let's get things a bit more stable first :) thanks, greg k-h _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
