Normally, the cfgadm -l command lists all dynamically reconfigurable hardware resources on a system, including USB devices. After you install the Solaris 9 4/04 software, the cfgadm -l command might no longer accurately list USB devices. Or, if you add the SUNWusb package by using the pkgadd command, this command might no longer accurately list USB devices.
Workaround: Choose from the following workarounds:
After you install the Solaris 9 4/04 software, run the cfgadm -l command as superuser only.
After you install the Solaris 9 4/04 software, do not add the SUNWusb package by using the pkgadd command. Instead, install the patch that is appropriate for your system:
For SPARC systems, install patch 115553-07, or a later version.
For x86 systems, install patch 115554-08, or a later version.
