I don't understand why that would be the case. libusb + libusbK seems like
the perfect solution for us especially when we consider the fact that we
are already using libusb in the Linux (x86 + ARM) environments with great
success. It just seems like the driver swapping is the main issue we need
to resolve.
Yeah I was aware that other products do the same thing but was just using
VMWare as an example. I forgot about the fact that VirtualBox is open
source though! I just installed it from scratch on a new PC and it asks to
install some driver at install time. Now to figure out how they get their
driver in when it comes time to "remote" a USB device to the VM.
Thanks,
Dave
