Hi all: I now make virt-viewer work now with USB support. however, When I select the usb device I want to redirect, it calls the error as follow: USB redirection error: Could not redirect USB Device: usbredirhost error: could not detach driver from interface 0 (configuration 1): -12 it seems that all my usb devices could not work well. What is the matter ? Can someone give me a help ? Thanks. <div class="gmail_quote">2012/12/5 flooding Controlled <<a href="mailto:flooding2012@gmail.com" target="_blank">flooding2012@gmail.com</a>> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi all: I have seen lots of packages on <a href="http://elmarco.fedorapeople.org/" target="_blank">http://elmarco.fedorapeople.org/</a>. and I think they may be useful for the build, but I don not know how to do this, did anyone try this, could you give some help ? and another question is, in the source directory of virt-viewer-0.5.3.tar.gz, there is no configure option for compile with usbdir and libusb , is it to be compiled auto ? Thanks. </blockquote></div>
