Yes, but then the OS has to have that lower layer.
So if we had a 'native' [non-M$] system, we'd have to provide

Yes, the device I need to connect [a fixed wireless terminal]
gives a vendorID/productID pair under linux, and linux hopes
to load the corresponding driver -- AFAICS. Which seems to
confirm my original suspicion that USB is 'complex like
NetCards and video-drivers', compared to RS232 &
I can't remember if N-O has USB?
But BlueBottle/A2 has; so that means A2 must have the
I HATE having to buy and use Win<something> just to use
this device!! Besides I don't [want to] know how to make
an ET.Do script in Win to auto-d/l 8 https.
Since I've got the native-A2 CD, it would be great if
native-A2s USB facility could handle it.
Is it realistic to try?

'clux' means 'click some mouse button/s, by just thinking
of what you want to achieve and your fingers will do it,
like [I guess] when a pianist sees the chord score, the
chord sound just happens.
