I would like to run a cups server and a saned server in a vserver with Debian SID because I would like to use my printer/scanner with others computer of my network. My scanner is usb and it works with libusb and sane. libusb need /proc/bus/usb mounted with usbfs to works, else, my scanner is not detected. Regards. -- .---.

Ok, I dit what you told me and now I've /proc/bus/usb in my vserver, but I haven't any access to /proc/bus/usb/*. When I mount usbfs and restart my vserver, my /proc/bus/usb stay empty in my vserver.

Ludovic RESLINGER wrote: Hi, I have a problem to use USB scanner using libusb in vserver. It seems impossible to access to /proc/bus/usb/* in vserver. I modified the /usr/lib/util-vserver/defaults/vprocunhide-files to add /proc/bus, but there is only /proc/bus/input and /proc/bus/pci. I added the line to fstap to mount /proc/bus/usb but it changed nothing. When I specify /proc/bus/usb in vprocunhide-files, I meet this error when I try to reload vprocunhide: (...) Fixing /proc entries visibility.../proc/bus/usb/: Invalid argument /proc/bus/usb/devices: Invalid argument /proc/bus/usb/005: Invalid argument /proc/bus/usb/005/001: Invalid argument (...) As expected, since usbfs doesn't support the flags. The way to get this working is a bit hackish, because you must unhide /proc/bus/usb _before_ usbfs is mounted there, alternatively something like: vnamespace -n bash umount -n /proc/bus/usb setattr --~hide /proc/bus/usb exit should do it. Note that you'll still need to have it in the guest's fstab. -- Daniel Hokka Zakrisson GPG id: 06723412 GPG fingerprint: A455 4DF3 990A 431F FECA 7947 6136 DDA2 0672 3412 ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
