Unprotect bitlocker drives (USB, Flash)

In order to remove the bitlocker requirement for thumb drive:
from :  http://windowsforum.com/threads/bitlocker-denying-write-access-to-usb-thumb-drive.78691/page-2
These two settings are mentioned on that site.
HKLM\System\CurrentControlSet\Policies\Microsoft\FVE!RDVDenyWriteAccess
HKLM\Software\Policies\Microsoft\FVE!RDVDenyCrossOrg

The RDVDenyWriteAccess was set to 1, but the RDVDenyCrossOrg was set to 0. After disabling RDVDenyWriteAccess, I pulled out my usb drive and re-inserted it. And I could write to it again!!

On my machine I see FDVDenyWriteAccess and RDVDenyWriteAccess and both set to 1.  I think FDV is fixed disk and RDV is removable disk.  You may only need to set the RDV but that is a complete guess

I did not have any the DenyCrossOrg in my registry
