@all: Sry for this off-topic posting !
I can confirm that the above mentioned USB WLAN stick works perfectly under
Debian and Trisquel 6.0 as well.
@mYself: Frankly it was not very clear to me that you were not against
ThinkPenguin :)
If you want to tell me that finding free hardware is not exacty that hard,
you are preaching the priest. I set up several systems (desktop though) with
Trisquel and beside GPUs the only hardware component I found which might
cause issues were NIC. Either WLAN or standard LAN. For normal LAN a cheap
Gigabit adapter from TPLink did the job for my two Trisquel boxes. For WLAN I
have now found a valid option as well.
I am also aware that I do not need to install Trisquel for using this WLAN
stick and have a free system. Debian would do as well.
May be not from the 100% free black and white perspective but from my point
of view (which is all that matters to me).
