Hi,

I guess it should be abstract enough to support multiple back-ends, be it a kernel driver or through libusb?

Is this something that should just live in libusb?

If what libusb presented QEMU was actually implemented as USB-over-IP, QEMU wouldn't know the difference at all. I think it would also be very useful to be able for libusb-based applications to work with remote devices.

What is unclear to me is what role QEMU would play in setting up remove USB-over-IP devices. Pushing it down to the libusb layer completely takes QEMU out the picture which creates a clean separation layer. There are emulated devices in QEMU which we create and control and then there are passthrough devices that QEMU doesn't have any role in creating.

Hi,

I'm note sure about what I will say, but will a kernel approach
handle specific disconnection/reconnection of devices, that libusb
cannot?

Don't know, didn't investigate (yet) what libusb can do and what it can't.

cheers,
Gerd
