A:Answer The j5create JUH377 USB-A 3.0 hub is intended for mostly mice, keyboards, flash drives and some external hard drives. We recommend plugging in one external hard drive to the JUH377 only and if there is a second external hard drive, please connect directly to the computer instead as the JUH377 is a low powered device. Even if the external hard drive may have it's own power source connected to it, it may not work due to it's power requirements when connected via the JUH377 device.
Yes, you should be able to transfer data from the computer directly to hard drive using the JUH377; just ensure to have the power adapter included in the packaging of the jUH377 connected for extra power to the JUH377 device.
Yes, you should be able to transfer pictures from a camera to the computer via the JUH377 device.
