It is possbile for bulk packets to transfer some of the data and to then stall. ATM our usb core allows us to return either data, or an error, not both. For now return the data rather then the stall when this happens, counting on further packets to detect the stall. In the future we should fix the qemu usb core to handle packets completing with some data and an error.
