USB devices
Note
USB peripheral devices that are to be connected directly must support
the USB 1.0/1.1 (Full Speed) or USB 2.0 (High Speed) standard. The
maximum data transfer rate is however in any case 12 MBit/s.
Keyboards, PC mice and barcode readers are so-called HID devices
(Human Interface Device) and can be connected via a USB hub only.
Printers should also be connected via a USB hub. Depending on the
manufacturer or printer type a direct connection is however possible.
