where can I get a driver to work with Windows 7 for my mustek 1200 ub scanner?
If Mustek do not supply a Win7 driver, and it looks as though they don't, try Viewscan. It supports the Mustek 1200 UB Plus, which uses the same drivers as the 1200 UB.
I have used Vuescan and it works well - very good for photograph scanning.
