Additional info: Provided /dev/bus/usb is mounted as /proc/bus/usb, an hand built usbutils-0.11, very old, fetched from http://www.lrr.in.tum.de/Par/arch/usb/download/usbutils/, solved the problem. Note that this comes with its own libusb. An hand built usbview-1.1 also behave correctly. It does not use libusb.
On the other hand, in spite of the mounting, all packaged I could fetch from http://sourceforge.net/projects/linux-usb/files/usbutils/ display the same faulty behavior. They all link against the installed libusb. ~$ apt-cache policy libusb-1.0-0 libusb-1.0-0: Installed: 2:1.0.1-1 Candidate: 2:1.0.1-1 Version table: *** 2:1.0.1-1 0 500 http://fr.archive.ubuntu.com karmic/main Packages 100 /var/lib/dpkg/status ~$ apt-cache policy libusb-0.1-4 libusb-0.1-4: Installed: 2:0.1.12-13 Candidate: 2:0.1.12-13 Version table: *** 2:0.1.12-13 0 500 http://fr.archive.ubuntu.com karmic/main Packages 100 /var/lib/dpkg/status -- lsusb lists nothing after upgrade to karmic (9.10) https://bugs.launchpad.net/bugs/459393 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
