CAUTION:
The next day of his installation: my laptop will not boot after several manipulations by unplugging everything, even to empty the battery overload, the PC restarts, I re-extinguishes, I reconnect the USB HUB, and ottoman ca restarts more , re Belote, disconnect all !!
Basically the Hub causes overload on my laptop, I'll return because I will not let anything like grilling my PC.
Large electrical problem with this product !!
