gpedit.msc and safely remove usb device

Hey there fellow geeks and geek-ets,

Have managed to seemingly snatch defeat from the jaws of victory - yet again.

Was configuring group policy this morning and went to lunch, then when i came back and logged in I decided that the usb device was no longer required for this build so removed it.... but NO:cry.. Somewhere along the way i must have set a policy to disable the removal of usb device as a popup tells me this has been disabled by the systems administrator ... me...idiot!:zzz:-o ..

This applies to all accounts including administrator.

Can some with better gpedit skills :cool inform me what I need to do to re-set this, so the usb devices can be safely removed...

Thanks in advance -L8r:wave
