Attention! Risk of short circuit! If the option described in this

section is activated, you may only connect or disconnect CAN

cables or peripheral systems (e.g. external bus converters) to or

from the PCAN-USB Hub while it is de-energized (the hub is not

connected to the computer). Consider that some computers still

supply the USB ports with power even when they are turned off

(standby operation).
