Vista - Driver problems

Hi, I have installed Vista Beta 2 onto my second hard drive partition, My
scanner driver appears to have loaded becouse it is within the control panel
, I can self test the scanner but when I attempt to use it it comes up no
software, the software part seems to have not loaded, has any body got any
workaround, the same has happened to my printer, it works but the status
monitor did not load.
the Printer is a R220 Epson and the scanner is a canon 3200f.
Any help would be appreciated.
