Hi all,<br>
<p>
I'm new to this list and I'm looking for some help/info/assistance for USB<br>
hp scanners. I've retrieved the SCL document from HP and read through<br>
portions of it that are related to SCL itself and USB. <br>
<p>
As for me, I'm currently involved in developing a USB driver for hp<br>
scanners with the Linux USB effort (<a href="http://www.linux-usb.org">http://www.linux-usb.org</a>). If anyone<br>
else is aware of any other envolvement/development, I'd like to hear about<br>
it. I've got the framework for the driver down but the scanner is not<br>
responding. Not even if I send a SCL reset code.<br>
<p>
Does anyone have any specific knowledge regarding any special<br>
initialization sequence for USB hp scanners (other than the standard USB<br>
initialization)? I've signed up (once again) for HP support and I'm<br>
waiting to see if I'll be accepted or denied. The first go-around I was<br>
denied but someone else was accepted. Since then HP has re-org'ed and all<br>
accounts reset, so we'll see what happens this time.<br>
<p>
My goal is to eventually have support so that SANE will be able to access<br>
such devices possibly using the 'connect-device' option in hp.conf. I do<br>
see usb in sane-1.0.1 (though not supported) and so I'm curious as to the<br>
current level of support and status.<br>
<p>
Also, if anyone is familiar with windows 98 and usb, does there exist what<br>
I call a 'wedge driver' that logs to a file all the data going to/from the<br>
usb subsystem?<br>
<p>
Thanks,<br>
/\/elson<br>
<p>
