[sane-devel] generic USB questoin (SANE/Avision and space USB)

[Rene Rebe]

Hi all,

currently I'm in the progress of converting the SANE/Avision backend
to do the USB I/O in userspace (using sanei_usb and so either
scanner.c or libusb instead of the Linux hpusbscsi SCSI emulation).

However I have a problem collecting the scanners status byte which the
hpusbscsi.c does via an interrupt URB:

	/* build and submit an interrupt URB for status byte handling */
 	FILL_INT_URB(&desc->controlurb,
			desc->dev,
			usb_rcvintpipe(desc->dev,desc->ep_int),
			&desc->scsi_state_byte,
			1,
			control_interrupt_callback,
			desc,
			desc->interrupt_interval

Any idea how I model this via sanei_usb (libusb) ???
