I'm working with the 2.4.18 kernel from Mandrake 8.2. Here is > the error output: The USB core can't handle data that is static. You need to have your urb buffer be created with kmalloc (I thought this was documented somewhere...) See the ezusb_writememory() function in drivers/usb/serial/usbserial.c as an example of how to handle writing firmware from within a kernel driver.
