Since a "cold" reboot, so genuine shutdown and later start up again, the above map is not (!) More recognized. A expansion, new installation, driver disassembly, re-installation, etc. did not help.
The USB flash drives receive power (the 4-pin liegts not, have another try), only it is not in the system recognizable.
Also in the Disk Management tool, they are not, in the Device Manager, the map no longer appears.
Map is now back unfortunately and I have to look for an alternative ... a shame.
Two stars, because it is not compatible with my system if necessary, however, in the first experiment 80MB / s write rendered ...
