If you are still getting crashes with the current Oneiric (with all updates), especially after suspend, try the package
cups - 1.5.0-8ubuntu7~ppa1
from my PPA
https://launchpad.net/~till-kamppeter/+archive/ppa
Its USB backend is based on the new libusb 1.0.x. Perhaps this helps as libusb 1.0.x has probably several bugs of libusb 0.1.x fixed.
The backend can still have bugs, so tell us exactly what the behavior is after having installed the new CUPS package.
