usbmgr: can't install or uninstall

[Charles Lewis <lewisc@delta.swau.edu>]

Getting the following error when I try to install usbmgr:

Preparing to replace usbmgr 0.4.5-2 (using .../usbmgr_0.4.6-2_i368.deb) ...
Stopping usbmgr: dpkg: warning - old pre-removal script returned error exit
status 1
dpkg - trying script from the new package instead ...
Stopping usbmgr: dpkg: error processing
/var/cache/apt/archives/usbmgr_0.4.6-2_i386.deb (--unpack):
 subprocess new preremoval script returned error exit status 1
Starting usbmgr: usbmgr.
usbmgr[23729]: umount /proc/bus/usb


If I try to remove the package:

Removing usbmgr ...
Stopping usbmgr: dpkg: error process usbmgr (--remove):
 subprocess pre-removal script returned error exit status 1
Starting usbmgr: usbmgr.
usbmgr[23749]: umount /proc/bus/usb

I tried using --reinstall. I tried removing the .deb and installing again.
And I've tried some other foolish things as well. What haven't I tried yet?
