After a bit more research, it looks like doing this with the SANE backend for HP 5590 is not possible. scanbd is used to tie custom actions to the options available on the scanner. In this case, none of the 10 options seem to return values. They all look to be ones that I designate from some client software.

scanbd: found active option[1] tl-x (type: 2) for device hp5590:libusb:001:008 
scanbd: found active option[2] tl-y (type: 2) for device hp5590:libusb:001:008 
scanbd: found active option[3] br-x (type: 2) for device hp5590:libusb:001:008 
scanbd: found active option[4] br-y (type: 2) for device hp5590:libusb:001:008 
scanbd: found active option[5] mode (type: 3) for device hp5590:libusb:001:008 
scanbd: found active option[6] source (type: 3) for device hp5590:libusb:001:008 
scanbd: found active option[7] resolution (type: 1) for device hp5590:libusb:001:008 scanbd: found active option[8] extend-lamp-timeout (type: 0) for device hp5590:libusb:001:008 
scanbd: found active option[9] wait-for-button (type: 0) for device hp5590:libusb:001:008 
scanbd: found active option[10] preview (type: 0) for device hp5590:libusb:001:008

In this case, it looks like I will have to try the old scanbuttond backends for this, or see if there are optional enhancements for the SANE hp5590 backend.
