Finally, a USB hub that works! ... I have two external drives that could not work with the old hub in my possession (regular brownouts). I finally resigned myself to not being able to use only one or the other by connecting alternately. And then I read the comments of users of this hub it. Still a bit skeptical, I decided to risk the thirty euros. What a good idea. It's been a week since my two disks rotate all day long without any sign of weakness of the Hub. What happiness!
