Description of problem:
After upgrading kernel to 2.6.23.1-21.fc7 usb support is limited. USB
connectivity no longer works on "advanced" devices such as cameras, only on
"simple" devices such as memory sticks.

Version-Release number of selected component (if applicable):
kernel 2.6.23.1-21.fc7

How reproducible:
always

Steps to Reproduce:
1. upgrade kernel to latest version (kernel 2.6.23.1-21)
2. plug in a camera via usb
  
Actual results:
The following error is returned:
An error occurred in the io-library ('Could not claim the USB device'): Could
not claim interface 0 (Operation not permitted). Make sure no other program or
kernel module (such as sdc2xx, stv680, spca50x) is using the device and you have
read/write access to the device.

Expected results:
Ability to access an "advanced" usb device - in this case a camera to be able to
import photos. PLEASE NOTE: booting up with a previous kernel release e.g
2.6.22.9-91 allows one to use the usb device successfully

Additional info:
I've done the test on 2 machines, both with the same result. In addition I've
also done a bit of google'ling on this and many people seem to have the same
problem after the latest kernel upgrade on various usb devices.

USB functionality is no longer a nice to have feature of an operating system,
please fix this issue asap. Also, please ensure that full usb support becomes
part of the testing cycle to ensure that something like this does not happen
again. Issues like this makes it difficult to use, support and promote a great
linux distribution (which I still feel Fedora is...)
