[sane-devel] Front Button Wait doesn't work via USB?

[Mark Longridge]

Hi folks,

I saw on the net a PDF file that said the front button 
does not work via USB in HP SCL scanners. Ok, I 
figured I would try directly and polled my 5200c 
scanner via USB with:

ESC s 1044 E 

and I always get "0" back. Also when I check "Front Button Wait"
on xsane it waits forever. It is true that the front button works 
when using a parallel connection? Anyone try it?

Thanks,
Mark
