-
Overall: Powerswitching using
uhubctldoes NOT work on all plugs! -
Positive: Power switching works every port (with limitations)
-
Positive: LEDs visible
-
Negative: Plugs are not numbered
-
Negative: Switching is very slow: 4s
-
Negative: Power switching does NOT work on Plug 1 to Plug 3. This limitation does not apply when using USB 2 (rasperry pi).
-
Positive: Plug switching may be done on Hub and remotely - not really - see below
-
Negative: If powered off manually, remote control des not work anymore.
-
Negative: If powered off automatically, manually control does not work anymore.
- None
