virtualbox.org

VB upgraded to vs 4.1.22. Guestsoftware also upgraded.
After that my usb-harddrive is available in the linux-host but not in VB anymore.
The drive is listed but VB says it's not available.
My usb-scanner is still working properly in VB.
Thanks for help in advance.

Did you upgrade the extension pack as well?

Yes. It has upgraded automatically.
Preferences, extensions says: Extensionpack 4.1.22 is active.
Meanwhile i found a solution by sharing the drive with vboxsvr. It works properly.
But It stays strange that usb suddenly isn't available anymore.
