I lost the CD to my USB->Emanage cable (made by Giff-Tech, excellent product) and needed the driver. It isn't posted on the net anywhere I could find. I contacted the developer, but after a day I didn't want to wait anymore, so I did some research.

I found through device manager that the usb->serial convertor in my cable was made by Polulu. You can download a driver here:


Here is some more info on the board used inside this cable:


This driver has been confirmed working in the 1.49 version of the e-manage support tool in Windows 7.
