Trisquel 8 is still alpha.
I do not really see the point of using openSUSE (which is quite bad,
freedom-wise) to transfer your smartphone's data. Use Trisquel. GNU/Linux
does not automatically files on a USB device (contrary to Windows still?).
http://libre.thinkpenguin.com and https://tehnoetic.com sell Wifi USB
adapters that are guaranteed to work with 100% free Linux kernels, hence with
100% free GNU/Linux systems such as Trisquel. As far as I know, they are the
only two companies doing so. On http://h-node.org you can find recent
reports of Wifi adapters working on 100% free GNU/Linux systems and hope the
chipset (what matters for the support) has not changed since then .
Manufacturers do that and there is no way to know but through testing.
You can buy an internal card too. However, there is a risk: Lenovo is known
o implement hardware DRM preventing the user from replacing the Wifi card
with a "non-approved" one, a white list.
