Permanently unloading the usb-storage kernel module under FC3

by Andrew Robert

Hi Everyone, I have a 160G NTFS partitioned USB external disk drive that I would like to use in my VMware instance. I tried to get VMware to recognize the drive but it failed to do so because the Linux USB driver had it locked. Removing and re-attaching the drive did not release the driver lock. What resolved the problem was to unload the usb-storage kernel module using the command: /sbin/rmmod usb-storage This works great but the module reappears the next time I boot the beast. Does anyone know of a way to make this permanently go away? Any help you can provide on this would be greatly appreciated. Thank you, Andy

Topic idea

by Mike Leo

Is there any interest in a linux fundamentals talk? It seems like I am the noobi'est member of the lug and don't want to bore everyone, but a discussion around basic installs (partitioning, swap size, boot loaders, etc), upgrades (apt, yum, emerge), application installs (rpm's, source) and kernel patching and upgrades would be a good nights discussion. I don't mind participating in the speaking, but I have plenty of questions myself. Just a thought. Mike __________________________________ Do you Yahoo!? Yahoo!

Re: [Wlug] Cups help

by Chuck Haines

Thanks to everyone's help, but I've figured out the backend stuff and written my own perl script that does the accounting using mysql. It's actually really neat and incredibly easy to use. I'm in the process of refinining it a bit now and if anyone is interested in it, I'd be more than happy to send it your way. It uses snmp to query the pages from the printer so it actually determines the number of pages printer and not just how many should have printed.

That was always the problem we had, esp when someone messed up and sent garbage to the laser printer at $0.10/page way back in the late 80s, and then came up to find a 1" thick stack waiting for them... with just one letter per page Or are you going to pre-render, count the pages, then get the page counter on the printer, print, and read the page counter to see what actually got through? I'd also google, since I can't imagine that you're the only one who's wanted something like this before... I'd try the cups-devel(a)cups.org mailing list (you may need to subscribe). This is actually a very hard problem if you don't have a printer that will do the accounting itself. Unless you can interpret the codes going to the printer, you can't even start to do this. -- Robert Krawitz <rlk(a)alum.mit.edu> Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- mail lpf(a)uunet.uu.net Project lead for Gimp Print -- http://gimp-print.sourceforge.net "Linux doesn't dictate how I work, I dictate how Linux works." --Eric Crampton
