[sane-devel] HP-scanjet 8250 (avision-backend) ADF-not supported

[Mike Kelly]

Thanks to the support of a few testers, especially S. Lipinski, I have  
been able to isolate the command sequence which gets the ADF working.   
Basically, the driver needs to send a reset command to the scanner,  
potentially solving both the initial ADF not working issue and the ADF  
failure after scanning a few pages.  Although I now know the right  
sequence to send, I still have to work through a rather annoying trial  
and error process of testing.  This process is being tracked in the  
Alioth bug system.

If you are able to download, patch, compile, and install sane- 
backends, please try out patch #5 from the bug, and post the results  
of the debug log to the bug system.

This link should take you to the correct bug entry:

Thanks,

Mike
