My bad. I had to reset my email account in thunderbird and now it needs
to learn anew what is spam and what is not. So I missed out on the
conversation as some messages (a lot actually) ended up in my spam folder.

Indeed. That is my gut feeling as well and if that is truly the case
your best option would be a cfg80211-based driver like ath6kl, mwifiex,
and brcmfmac.

If there are linux users with this hardware than sure. Especially if it
revised to interface with the latest wireless subsystem so tools like iw
can operate on it.

Also I suppose it is preferred if a driver is maintained. I do not see
the ks7010 listed in the MAINTAINERS file yet.
