fingerprint scanner no longer works with new kernel
When you try to access the fingerprint reader, the following error is produced:
"Could not acquire fingerprint (USB error)."

Additional info:
* package version(s)
thinkfinger 0.3-2
kernel26 2.6.28-3

* config and/or log files etc.
See attached kernel patch for the fix that worked for me.

Steps to reproduce:
root ~ # lsmod | grep uinput
uinput 10752 0
root ~ # tf-tool --acquire

ThinkFinger 0.3 (http://thinkfinger.sourceforge.net/)

Please attach the patch you mentioned.

Is this a kernel patch, or a patch to thinkfinger. Any way to fix this at the thinkfinger level rather than the kernel level?

Here is the patch.
AFAIK this is a kernel bug in and is supposed to be patched into one of the -stable releases.

What is the source of the patch? If it is upstream, mailing lists etc, please post a link to it.
