Review on 7-Port USB Hub with Individual Switches and Indicator Lights for PC Laptop - Black-2 by Aavon Dark

I really like the number of ports on this unit. It was also a killer prize. I didn't think I could max it out, but I have a couple of USB sticks, a card reader and the rest to charge various devices. I love the switches and the long cord is very useful. My problem is that I keep getting messages that all attached media is disconnecting. This could happen when I unplugged a charged item. Don't understand why that would happen. I used to not turn off the device because it doesn't show up on the desktop. That may be a problem now as I write this. However, this is exactly what could happen randomly, even if the item was not connected to the device. Still looks like a device, but I'd like to understand why this is happening. Therefore I give 3 stars.
