The usbredir’s version I built is usbredir-0.5.2 So, thanks for your help. And here are two question again.^_^ 1. How to build a MSI file from the packages I Built. 2. Does spicy-gtk support a feature that let a uKey connected To client and guest and the same time. _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/spice-devel
