Review on 💻 High Speed USB 3.0 Hub Splitter - 4 Port Multiport Slim USB Hub Adapter with 9.8" Cable and LED Indicator – Portable Mini USB Expander Hub for MacBook Air/Laptop/Ipad/PC, Compatible for Fast Data Transfer and Charging by Chris Palmer

Update: This hub is actually only for flash drives (requires less power). The first bug was due to connecting two external hard drives at the same time, which required higher currents that the hub couldn't handle. I will keep it for other purposes. (Previous Review): It cannot detect two devices at the same time! Connecting a second device removes the first from the display on the computer, disconnecting the first also removes the second device. Also, when the devices are connected, it starts beeping for about 10 seconds, it looks like it is trying to read the devices but failed in the end. It doesn't match what it says. i will return it
