I found that these entries in /etc/dacf.conf formerly present in
Osol 2009.06 are missing now:

# Configure and/or unconfigure usb audio devices.
# usb_ac as a mux for hid and usb_as devices.
driver-minorname="usb_ac:mux" usb_ac_dacf:usb_audio_config post-attach -
driver-minorname="usb_ac:mux" usb_ac_dacf:usb_audio_config pre-detach -

The /etc/driver_aliases entry is still there, the /kernel/drv/usb_ac is
there, and the /kernel/drv/usb_ac.conf file has this promising entry commented:
# Uncomment reset-configuration to cause the usb_ac driver's state to
# be reset to the default when the driver is loaded. Otherwise this state
# is retained across driver unload/reload cycles, but not across reboots.

Maybe inserting the above lines and uncommenting this one followed
by a reboot helps ?
