<html><body><div style="color:#000; background-color:#fff; font-family:arial, helvetica, sans-serif;font-size:10pt"><div style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">I created a neat setup using xinet + scanbd service + scanbd daemon (for buttons) + sane (client) to use Epson GT-1500 (with ADF) as a workhorse of a network scanner, with scanner buttons hooked to various jobs. Everything is working great, except...</div><div style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><br></div><div style="font-family: arial, helvetica, sans-serif; font-size: 13px; color: rgb(0, 0, 0); background-color: transparent; font-style: normal;">I encountered a problem after the scanner is powered off and then on again. The buttons service (scanbd daemon) stops reading the buttons and keeps getting "communication error" in the syslog.</div><div style="font-family: arial, helvetica, sans-serif; font-size: 13px; color: rgb(0, 0, 0);
background-color: transparent; font-style: normal;"><br></div><div style="font-family: arial, helvetica, sans-serif; font-size: 13px; color: rgb(0, 0, 0); background-color: transparent; font-style: normal;">I tried various things until it occurred to me that Epson GT-1500 uses iscan plugin that loads firmware file (/usr/share/iscan/esfw86.bin) and the power off-on resets the scanner and thus wipes out the firmware. It seems like scanbd daemon does not load the firmware when the scanner is powered back on (at least I was not able to find how to configure it to do so), and it gets into trouble trying to read the buttons from device without its firmware. </div><div style="font-family: arial, helvetica, sans-serif; font-size: 13px; color: rgb(0, 0, 0); background-color: transparent; font-style: normal;"><br></div><div style="font-family: arial, helvetica, sans-serif; font-size: 13px; color: rgb(0, 0, 0); background-color: transparent; font-style:
normal;">I have few questions to scanbd team:</div><div style="font-family: arial, helvetica, sans-serif; font-size: 13px; color: rgb(0, 0, 0); background-color: transparent; font-style: normal;"><br></div><div style="font-family: arial, helvetica, sans-serif; font-size: 13px; color: rgb(0, 0, 0); background-color: transparent; font-style: normal;">1. Can scanbd daemon automatically load firmware file and what should be done in the config files to achieve that? sane config files seem to have "firmware" option, but I don't see anything in scanbd documentation.</div><div style="font-family: arial, helvetica, sans-serif; font-size: 13px; color: rgb(0, 0, 0); background-color: transparent; font-style: normal;"><br></div><div style="font-family: arial, helvetica, sans-serif; font-size: 13px; color: rgb(0, 0, 0); background-color: transparent; font-style: normal;">2. If scanbd daemon currently cannot load the firmware, are there any plans to add this
feature?</div><div style="font-family: arial, helvetica, sans-serif; font-size: 13px; color: rgb(0, 0, 0); background-color: transparent; font-style: normal;"><br></div><div style="font-family: arial, helvetica, sans-serif; font-size: 13px; color: rgb(0, 0, 0); background-color: transparent; font-style: normal;">3. If not, what is the recommended way to set scanbd up so it will work with scanners that require firmware to be loaded?</div><div style="font-family: arial, helvetica, sans-serif; font-size: 13px; color: rgb(0, 0, 0); background-color: transparent; font-style: normal;"><br></div><div style="font-family: arial, helvetica, sans-serif; font-size: 13px; color: rgb(0, 0, 0); background-color: transparent; font-style: normal;">I spent few hours and came up with the following rework using udev rule that invokes "scanimage -L" command to pull the command chain that loads the firmware. It works fine and I have not seen "communication error"
since.</div><div style="font-family: arial, helvetica, sans-serif; font-size: 13px; color: rgb(0, 0, 0); background-color: transparent; font-style: normal;"><br></div><div style="font-family: arial, helvetica, sans-serif; font-size: 13px; color: rgb(0, 0, 0); background-color: transparent; font-style: normal;">A.
