What do you mean? If you mean: "of course the ioctl callback can be called during disconnect, just like for other reads and writes", well I agree. I didn't write the driver, I'm trying to fix it so it works with SMP; this looks like an obvious race in the driver (ioctl during disconnect), but I would like to be sure. Maybe the driver author knows something I don't... All the best, Duncan. _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
