Thank you very much for your help.

Indeed, the "Tape device" button finds the 2 3580 drives are tries
toload the 3580 drivers.

A Cancel is necessary to prevent him from loading the 3580 drives.

I went in the drivers tab and forced him to load the 3583 driver. I
rebooted and ... miracle, the 3580 drivers
are installed as well as the 3583 driver.

Thank you again,

Ruddy
