Re: [Qemu-devel] [Qeustion] USB passthough doesn't work on Windows.

[Geunhae Lee]

hi thanks for you kind answer, 

admit about lacking of infos haha..

here's my situations. 

1. i currently use QEMU ver 1.2, but plan to upgrade to 1.5 soon. 

2. in version 1.2, i found that USB passthrough is not supported on Windows/Mac. 

    In version 1.5, however, it seems possible to use passthrough by re-implementing usb host (libusb)  , right? 

    

    but i didn't find out any former work which uses USB passthrough on Windows and Mac

 so my questions are 2 followings. 

1.  is there any articles about using USB passthrough on Windows and MAC 

2.  do you guys have some performance issues? 

     -  libusb vs former implementation (qemu ver 1.2)

     

have good day

Your question is lacking too much information to answer:
* Are you using today's Git version? Or which stable version?
* Define "not working": build errors? runtime errors?

I would expect the new libusb-based backend to work on Windows/Mac but
it requires a very recent library version, which you may need to update.

Also it may help if you CC'ed the USB maintainer on your question. :)

Andreas
