Alan, Thank you! Thank you! Thank you! Who'd have thought such a simple patch could make someone so happy? That did the trick. I just tried it and it works beautifully whether the device remains plugged in during suspend or if it's unplugged and plugged back in during suspend and before resume. Now if this could only become the default behavior ;-) Thanks again, Raymano G. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
