Okay. Let me rephrase this: Lets say there is a read request for 4096 bytes and your maxpacket is 512 and total of 4096 bytes will be sent by the device. How many interrupts / read requests will there be? 8 like every maxpacket size or is it possible to stuff more data and transfer 4096 in one go? >>> Cheers >> Sebastian -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
