I bought 2 of this same, one in China, one in Honk Kong, the one i bought in China works fine, tested on, Solo, Solo Se, Solo 2, the one bought in Honk Kong works ok with Solo, but not work well with Solo Se, and Solo 2, i did lot of tests but could not make work 100%, what i do to work is, i have to install or uninstall plug in Reboot in order for the USB to come to live, otherwise the channels go missing, it says check tuner configuration, what strange with this is, they are 100% same, i could not see any difference with them, if some one has any advise please let me know, thanks!!!
