I installed Windows10 on my Linux Distro, as there are still no FOSS solutions to update a Garmin GPS and to backup/manage an iPhone.
I found out that Gnome Boxes is nice but useless, as the iPhone crashes the Win10 Machine due to the USB not being reverse-compatible to USB-2(ehci), but that 'Virt-Manager' works, if you adjust it to USB-2 from the drop-down menu.
