I have tried this with the lego usb tower and I am getting the following error on writing: USB error: error submitting interrupt URB: Invalid argument I am calling this function using the following: usb_interrupt_write(tower->dev, tower->outepoint | UT_WRITE, (char *) buf, nbytes, LINUX_USB_TIMEOUT); Any ideas what the invalid argument is?
