The USB hub I ordered as a replacement for scanner, printer, mouse, keyboard, etc. now use all USB ports on my PC and the corresponding connections were assumed. I had before, printers and scanners connect to the hub, since it virtually never transferred to my mind at the same time data and each have their own power supplies. According to product description is using Plug and Play function on Windows XP SP3, the stroke. After connecting the USB hub alone (ie even without connecting devices to the USB hub) no longer worked, the device connected to another USB port on the PC external hard drive. Windows asked whether it should be reformatted. After removing the USB hub and recently Removing and replacing the board was working again. With a scanner to the USB hub connected while alone came on the PC screen and release the message that a new device has been installed and it went to the scanner lamp, but the scanner does not initialized, so that he scan of the software could not be found. After direct connection of the scanner instead of the USB hub to the same USB port on the PC, the scanner was working again.
The USB hub is not a manual, so I have no information as might be encountered such problems, if only certain types of devices can be connected to the USB hub or if the PC has efüllen certain requirements.
