The 0xa0 is needed for devices like the WhiteHEAT that first loads a special loader into the EZUSB device, and then loads extra firmware. It uses two different commands to get this to work. See the current drivers/usb/serial/whiteheat.c file to see how this works, and why it is necessary. There is also a script in the drivers/usb/serial directory that takes Intel hex records and converts them to the format used by the current drivers (a .h file full of records.) That script can be modified to do some other kind of output if you wish. thanks, greg k-h _______________________________________________ Linux-hotplug-devel mailing list http://linux-hotplug.sourceforge.net Linux-hotplug-devel@lists.sourceforge.net http://lists.sourceforge.net/lists/listinfo/linux-hotplug-devel
