Hi Marco,
thanks.
I think you mean this thread : Sharing USB cable between IR and VC?
Right ?
I read this too, but this is a speculation and not a fact, right ?
To clear this up a bit, i don't want to access this Hub, but want to know if
that's the way LEGO (logitech) made it.
What i wanted to know is, why are two devices in the
system-properties under the LEGO USB Camera ?
-USB Root Hub
-- LEGO USB Camera
--- LEGO Cam
--- LEGO Cam Microphone
I assumed that the LEGO USB Camera device is a USB
Hub (without possibility of external connection of course)
and the LEGO Camera and the LEGO Camera
Microphone are the two devices connected to this Hub.
Thanks anyways,
Rainer

| Well, I think someone here said that there's an *internal* "micro" USB hub, unusable to someone not familiar with microelectronics. That internal "micro-hub" provides a way to "mix" the usb-microphone with the usb-camera into one usr-cable. I don't (...) (23 years ago, 23-Nov-01, to lugnet.robotics)
