DO NOT buy this device if you want to use it with flash or thumb USB drives or unpowered USB external hard disks!!!
Had the same problem as everyone else with this device, complaints about not enough power to power the device. According to tech-support, the USB ports are UNPOWERED, which means the USB hub is completely useless for devices that aren't self powered. Good bye using these really nice, snazzy front ports for USB flash drives.
Tech support also stated that announcements were sent to resellers to make sure that customers knew this. Maybe I missed it (it's possible), but I don't see any disclaimer on the Amazon page for this product. If it is there, but I missed it, I suggest Amazon make it much BIGGER, maybe red or flashing...
