todd_l, Have you tried installing the Win7 64-bit driver for the Ricoh controller from support.dell.com?  It's available here, if you want to give it a shot.
In updating to Windows 7, the only driver it didn't find was for my Bluetooth 370 Module 2.1.  When I go the the web site, looks like there are 2 Vista drivers shown that say Bluetooth.  Should I pick on of those, or try the Dell disk?
