Backup Exec 2010/Dell RD-1000 Drive Issue

Hi,

I've connected a Dell RD-1000 Drive via USB to a server (Windows Server 2008 R2 Standard), which I'm having problems with it being recognised/picked up within Backup Exec 2010.

I've downloaded and installed the correct drivers for this tape drive and the actual server recognises it without a problem (it's assigned as a removal disk to the G drive).

When I go to the 'Devices' tab within Backup Exec and select 'Add Device', it says no other devices were found.

Let me know if you need anymore information, but I'm thinking maybe this hardware doesn't work with Backup Exec 2010..?
