Scanner software has no driver for HP scanjet G4950

I have an HP ScanJet G4050 attached to via USB. None of the Linux scanner software recognizes it. I checked the HP web site. No Linux driver so I downloaded the windows driver. When executing the windows driver under wine, I get an error message that it can not find the USB driver. When the scanner is plugged in and turned on, it does not show up as /dev/ttyUSBx (x=0 or 1). If it did show up as a tty, I could link to com1 . The output of lsusb is:
