Looks like the device is emulating a CD-ROM which offers driver files
to MS-Windows for automatic installation. The web says that this happens
when the device does not get the right answers from the operating system
which indicate that the drivers are already installed.

An Archlinux thread proposes to use a program named usb_modeswitch to get
the device out of this mode
  https://bbs.archlinux.org/viewtopic.php?id=228195
Debian has it in a package
  https://tracker.debian.org/pkg/usb-modeswitch

I find its home page somehow confusing
  https://www.draisberghof.de/usb_modeswitch/
But the web says that it is supposed to work automagically for known
devices.


Have a nice day :)
