Maintenance And Cleaning; Technical Data - Renkforce 1342481 Bedienungsanleitung

• The theoretical maximum speed for USB3.0 (or also USB2.0 or USB1.1) is never
achieved in practice. This is due to protocol information, simultaneous operation of
several USB devices or the speed limit of the connected device or the USB control-
lers/ motherboards.
It also makes little sense to simultaneously operate 3 hard drives via the USB hub, as
these share the possible volume of data transmission between the hub/card reader
and computer.
If, for example, a lot of data is to be transferred between two USB3.0 hard drives,
connect the first hard drive to the USB hub and connect the second directly to a
USB3.0 port on the computer.
• Normally USB operation is not possible in DOS or in the protected mode of older
Windows versions. Depending on the computer or the BIOS/Setup, however, opera-
tion of a USB keyboard and a USB mouse is possible. Nevertheless, it is necessary
to connect them directly to the computer's USB interface and not to the USB hub.
• USB devices can be connected and disconnected during operation. You do not have
to switch off your computer if you want to insert or remove devices.
If data transfers are in progress on the USB port, e.g., if an external disk is writing
data to the computer, and you unplug the USB plug, the operating system might
crash. Furthermore, this may result in loss of data or damage to the file system of
the external drive.
• In Windows XP, Vista™, 7, 8, an icon with an arrow in the menu bar is displayed for
®
some USB devices (e.g. for a USB hard disk). With this function you can "discon-
nect" the USB device from the computer so that data transfer ceases to occur. Af-
terwards, the USB device can be disconnected from the USB hub (or the computer)
without problems.
