Hi, I am new to USB world and looking for clarification on usb printer's behavior when transferring data with size multiple of wMaxPacketSize.
I have been running redhat 7.1 (linux kernel 2.4.2-2) on a x86 PC with a USB 1.1 controller. There is a target mode printer driver running on the other side. On the host the device file is /dev/usb/lp0. If a data packet of 64 bytes is sent with "cat data8 > /dev/usb/lp0" , the size of data8 is 64, a zero length packet at the end of the transfer is not sent. Is this a correct behavior? How do we force the printer driver send a zero length packet at the end of a transfer if the packet size is a multiple of wMAxPacketSize?
