NOTICE
Damage to the USB thumb drive and malfunctions due to data loss!
Removing a USB thumb drive while it is still in use and data is being transferred can render the
USB thumb drive unusable. Open files which cannot be accessed due to removal of the USB
thumb drive can block the device.
Therefore, ensure that all data operations are complete before removing the USB thumb
drive.
NOTICE
Property damage and malfunctions due to data loss!
The USB interface is protected against overload (> 0.5 A). In the event of a short-circuit during
operation, the controller can trigger a system reset.
This can result in considerable damage to property and damage to the USB device.
Before using a USB device, check its power consumption.
NOTICE
Failures and malfunctions when connected directly to signal ground!
Only use USB devices that do not have a direct connection between the signal ground
and the housing.
USB thumb drives can be inserted and removed during operation. The inserted USB thumb
drive is detected automatically and appears in the Linux directory/media/usbX. When the USB
thumb drive is removed, the directory /media/usbX is again removed from the directory struc-
ture.
Either the first partition on the USB thumb drive, or, if the memory is not partitioned, the entire
memory will be connected, i.e., the respective directory appears automatically.
The X represents a number from 1 (first USB device) to 8 (last/max. USB device).
The mechanical construction of the USB interface is designed for up to 1000 plugging
cycles.
