USB Power when unit is switched off

Post by RISC »

Is there power still available at the USB connectors when the PC is switched off.

Edit:
In fit-PC2 rev 1.2, rev 1.21 USB is powered when the fit-PC2 is off.

Hi,

How do I know what Rev. my FIT-PC is? I ordered mine about an month ago and the USB is NOT powered off when the FIT-PC2 is shutdown or in hibernate mode (S3). It has the "auto on" option though (automatic starts up when power is applied).

Your board is 1.21 if it has IR and 1.2 if it does not have IR. Most chances your board is 1.21. The USB is NOT powered off in 1.2 AND 1.21.

That is absolutely correct: I have IR and USB is not powered off :(
