If it is for your development use, the filter driver is okay. We still do not recommend to deploy filter driver to end users as potential problems can still occur, including BSODs in some circumstances. -- Xiaofan ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ pyusb-users mailing list pyusb-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/pyusb-users
