I have a Signametrics SMU2064 usb box. Signametrics where bought by Agilent in 2010? and Agilent do not maintain software /drivers any more. I'd like to run it under W64 if I could find usb drivers / updates. It seems like Pickering, Marvin are producing some of the Signametrics boxes, at least PXI versions. I have tried their software but it seems usb drivers are not included. I think there are ftdi usb ic's in there... Does anyone here have any experience in these, ideas on how it could be solved?
