&gt;&gt;&nbsp;Hi,
&gt;&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I&nbsp;have&nbsp;an&nbsp;old&nbsp;Uniscan&nbsp;D50&nbsp;USB&nbsp;scanner,&nbsp;which&nbsp;was
&gt;&gt;&nbsp;produced&nbsp;by&nbsp;a&nbsp;Chinese&nbsp;company,&nbsp;Qinghua&nbsp;Ziguang.
&gt;&gt;&nbsp;I&nbsp;tried&nbsp;in&nbsp;Fedora&nbsp;8/11/12,&nbsp;but&nbsp;it&nbsp;didn't&nbsp;work.&nbsp;Some&nbsp;useful
&gt;&gt;&nbsp;information,&nbsp;I&nbsp;think,&nbsp;is&nbsp;that&nbsp;when&nbsp;adding&nbsp;a&nbsp;line
&gt;&gt;&nbsp;usb&nbsp;0x1606&nbsp;0x0170
&gt;
&gt;You&nbsp;are&nbsp;running&nbsp;a&nbsp;very&nbsp;old&nbsp;sane-backends.&nbsp;Too&nbsp;bad&nbsp;it&nbsp;does&nbsp;not&nbsp;give&nbsp;any
&gt;information&nbsp;about&nbsp;the&nbsp;chipset&nbsp;used.&nbsp;I&nbsp;suggest&nbsp;you&nbsp;try&nbsp;the&nbsp;latest
&gt;sane-backends:&nbsp;1.0.21.&nbsp;Maybe&nbsp;you&nbsp;will&nbsp;get&nbsp;more&nbsp;useful&nbsp;information&nbsp;from
&gt;it&nbsp;because&nbsp;at&nbsp;latest&nbsp;sane&nbsp;I&nbsp;note&nbsp;that&nbsp;there&nbsp;are&nbsp;several&nbsp;models&nbsp;of&nbsp;the
&gt;brand&nbsp;UMAX&nbsp;that&nbsp;have&nbsp;the&nbsp;0x1606&nbsp;vendor&nbsp;ID&nbsp;and&nbsp;are&nbsp;supported&nbsp;by&nbsp;a
&gt;variety&nbsp;of&nbsp;backends&nbsp;depending&nbsp;on&nbsp;the&nbsp;chip&nbsp;used:
&gt;
&gt;-&nbsp;plustek
&gt;-&nbsp;rts8891
&gt;-&nbsp;umax1220u
&gt;
&gt;So&nbsp;please&nbsp;see&nbsp;what&nbsp;output&nbsp;you&nbsp;can&nbsp;get&nbsp;from&nbsp;the&nbsp;latest&nbsp;SANE.
&gt;
&gt;Best&nbsp;regards,
&gt;Gernot&nbsp;Hassenpflug
