the "deprecated" hpusbscsi driver in the kernel - but _not_ the
scanner driver.</I></FONT></PRE>

<FONT SIZE="4"><B>I've tried so many configuration variations over the last couple of weeks that I've gotten confused about what configuration settings do what. I don't think I understand the terminology.<BR>
<BR>
I now think I should avoid using the scanner driver. Would<BR>
rmmod scanner <BR>
do this for me, or is something else necessary? How can I tell whether or not I am using the scanner driver?<BR>
<BR>
I would like to use libusb, but I have not been able to figure out what causes the libusb driver to be loaded. Some parts of my system refer to usbfs; others refer to usbdevfs. I think I need everything in the system refering to one or everything to the other, but when I tried changing the usbdevfs references to usbfs, I produced a system that would not boot, and had to restore a backup.<BR>
<BR>
What is the best way to get back to a clean system?<BR>
Is there a modprobe command I should be using to load the libusb driver? If so, should I add it to /etc/rc.d/rc.local to get it to run during boot?<BR>
My guess is that </FONT><BR>
<FONT SIZE="5">modprobe scanner vendor=0x03f0 product=0x0801</FONT><BR>
<FONT SIZE="4">should be added to /etc/rc.d/rc.local. Is that right? If so, what else needs to be done?<BR>
<BR>
What should be done to get the scanner mounted as rw with permissions for everyone to use it? The things I have tried with fstab did not work, since the system tried to mount it twice.<BR>
<BR>
I currently have hpusbbscsi disabled. Should both libusb and hpusbbscsi be enabled?</B></FONT><BR>
