Some people have had success with the Berlios AT7C503A driver. You can find a table at http://at76c503a.berlios.de/devices.html where both variations of the F5D6050 are listed as working with that driver. I, however, have failed with that specific driver. I no longer posses the unit but rumour has it that there is a Mandrake RPM containing an update version of the driver. It may work with both F5D6050 and F5D6050 version 2.
