[sane-devel] Cardscan 800c device busy

[John G. Lynn]

Hello everyone,
I seem to be having some problems with a Cardscan 800c.

Using 1.0.19 on both CentOS 5.2 and SlackWare 12.1 returns similar results.
libusb is current on both.  I have used/built the provided packages  
(from Fedora 10) and the tgz from the sane ftp.

One one computer with an Intel mother board I can get 4 or 5 scans  
before I get a "device busy", and in a couple of minutes it will let  
me scan again.

On the other computers ( all are Shuttle with SiS chipsets )  I seldom  
can get a scan and never 2 in a row.

All work is done on the command line.

Below is the debug tracing.

I am open to trying anything.

Thank you for your time,
jgl
