I tried to use a toshiba usb 2.0 memory stick plugged into the PLUGABLE 10-port 2.0 USB hub, and I get the message that it cannot recognize the device. It works OK with other hubs like the 7-port Belkin USB 2.0 hub or plugged directly to the computer USB. The Toshiba unit is a 16 GB memory stick and is 2 months old bought at STAPLES.
My computers are 2-descktops HP computers, a Toshiba laptop with USB 2 and USB 3 ports. My operating system is Windows 7 64 bit with all the latest updates, and the USB driver is a generic Microsoft driver. I have about 10 memory sticks of different manufacture (PNY, Sandisk, HP, Phillips, and DT101 G2) and they work perfectly well with the hub.
The hub is connected directly to the computer and uses the supplied A/C cord. I tried all the connectors on the hub without success.
