The standard situation:

Installing ntfs-3g solves the problem.

 If you'll uninstall ntfs-3g after sucessful redirection but won't restart usb-share service and plug device again it will be again sucessfully redirected (I believe it's due some device cache build by daemon).

But some guys can't install "unsupported applications" and need to use ntfs on their flash drives (e.g. due MAX_FILE_SIZE of fat)


Version-Release number of selected component (if applicable):

spice-client-0.7.2-1.el6.x86_64
spice-xpi-2.4-2.el6.x86_64
kmod-kspiceusb-rhel60-4.9-14.el6.x86_64
spice-usb-share-4.9-9.el6.x86_64


How reproducible:


Steps to Reproduce:
1. sudo /etc/init.d/spiceusbsrvd stop
2. rpm -e ntfs-3g
3. sudo /etc/init.d/spiceusbsrvd start
4. Connect to a windows guest
5. plug in usb drive
  
Actual results:

Unable to mount ... on the client

Expected results:

spice-usb-share deamon should still recognize device and forward it.
