Hi, backend author here - it shouldn't be too much of effort to expose button status so scanbd can use it. Though haven't gone thru its documentation to understand requirements. As a technical insight - there is hp5590_read_buttons() function in hp5590_cmds.c that reads button status. However, I'll seek for a volunteer to test a change as I don't have access to HW currently.
