lsusb does not show all devices
This document (7008431) is provided subject to the disclaimer at the end of this document.
Although the devices show up in /var/log/boot.msg they are not displayed with 'lsusb'.
For example on SUSE Linux Enterprise Server 10 'lsusb' returns:
Bus 002 Device 001: ID 0000:0000 Bus 004 Device 002: ID 04b3:4001 IBM Corp. Bus 004 Device 001: ID 0000:0000 Bus 003 Device 001: ID 0000:0000 Bus 001 Device 001: ID 0000:0000On SUSE Linux Enterprise Server 11 'lsusb' returns:
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hubUsing:
# mount -t usbfs usbfs /dev/bus/usb
# udevadm trigger --subsystem-match=usb
makes the device(s) appear.
It installs the file "/etc/udev/rules.d/50-udev-default.rules", but default rules are in /lib/udev/rules.d and not in /etc/udev/rules.d/.
Files in /etc/udev/rules.d/ have precedence over files with the same name in /lib/udev/rules.d/ and therefore the file in /etc/udev/rules.d/ is overwriting the default rules file from udev in /lib/udev/rules.d/, causing the problem.
Removing the RPM and rebooting or running 'udevadm' resolves the problem and the devices show up.
Customers affected by this issue can contact SUSE Technical Services to request an intel-iamt package without the /etc/udev/rules.d/50-udev-default.rules file.
On SUSE Linux Enterprise Server 11 Service Pack 2 the intel-iamt package is not included anymore.
Since the package is not maintained anymore there won't be any future support or development. Therefore, the package may as well be removed instead.
