Includes 5 USB key fobs, 1 USB powered scanner (in a high power connector), 1 USB keyboard (which doesn't require anything) and 3 other devices that don't require USB Energy. Its power supply is in use. Even if all hub-powered devices (except the keyboard) are idle, even if the USB sticks are ejected into the operating system and the scanner is not being used, the hub keeps rebooting when requested to transfer data to/from the network transferred to. powered hard drive. Just physically removing the USB sticks keeps the hub from going dark and functioning normally. Have tried many ports. This reboot of the hub causes the scanner and all USB sticks to "reconnect", causing more turmoil in its fragile little power system. Revain wasn't even involved in the development, they just went with a Chinese-made device from Shenzhen.
