hotplug script goes bonkers with 2.6.1

hotplug script goes bonkers with 2.6.1

[John H.]

After I upgraded to 2.6.1 from 2.6.0(I tried upgrading my modutils and module-init-tools to latest versions to see if that would fix this, but it would not), I get this when loading hotplug script(even the latest one, which I upgraded to as well)

RE: hotplug script goes bonkers with 2.6.1

[John H.]

unplugging scanner before running hotplug seems the temporary solution.

any ideas on a long term one?

Yes, don't use the scanner driver at all :)
It's obsolete and you can just use xsane through usbfs instead.

It's a bug in the scanner driver that is causing this.  Please let the
scanner driver maintainer know about it.

thanks,

Re:hotplug script goes bonkers with 2.6.1

[Leon Cogs]

Same here. 

I unloaded scanner form kernel but I don't know how to set it up 
otherwise as advised

"you can just use xsane through usbfs instead"

.   I have looked all over.  Below is a line in /etc/sysconfig/hotplug 
could this cause bother if scanner modules has been deleted from kernel?

##Type: string
##Default:  scanner
##ServiceRestart:
#
HOTPLUG_USB_MODULES_TO_UNLOAD="scanner"

Also printer epson 740 doesn't load as a module unless I modprobe usblp 
and then set it up in Yast2 Suse 9,  How is this done.

Another problem is a maxtor usb2 hard disk  and iomega usb2 cdwriter 
which dont hotplug in 2.6.1-rc1 Below are 2 lines which I included in 
fstab which seem to access these devices at the moment, but I am not 
sure about.
/dev/sda1   /media/sda1    auto   sync,noauto,user,exec 0 0  # for ext hd
 dev/sr0   /media/sr0   auto   ro,noauto,user,exec   0 0  #for writer

deleting scanner module and rebooting seemed to fix it.



however, xsane now no longer sees my scanner.

help?

most modules work for me, have you module-init-tool installed.  I use 
module-init-tools  0.9.14 also  use hotplug-2002_08_26-85, Suse 9 pro.
However, printer epson 740 does not load as module and epson perfection 
scanner also.
