I have it for more than 1 year and I kinda' need it even if the usb3 won't work... at least I can use the 2 ports to dirrectly connect 2 drives...nothing else is wrong and I wouldn't of known if I wouldn't of got these hubs... My only solution if no more debugging can be done is to get a nas a put the drives in it... Maybe it's the drives fault somehow ? maybe we should mail wd ? manhattan's fault ? via ? :) There must be someone/someway/somehow that can analyze it in someway and say what is wrong .. Still weird..I'll try on another laptop tomorrow or so ( a dell inspiron with an usb3 port .. dunno what usb3 root chipset it has ) -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
