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) ???
