OK, although I will need to read the other endpoint for image data, that apparently is not the issue I'm hitting right now.
I can open the scanner. I can send it short INQUIRY and get the requested data block back then read status. I can send it long INQUIRY and get the requested data block back then read status. I can send it READ ATTRIBUTES and get the requested data block back then read status. I can send it READ SYSTEM STATUS, but instead of getting my data block back, I get one byte (00), and it timeout on trying to read additional bytes. It is almost like the RSS data block is not being sent and the status byte is the one byte I am reading. It appears that both prior developers of the microtek2 backend are not involved any longer, so I guess there is no help from them. Steve
