I am using the NUC DE3815TYBE for an embedded system and I need to use the three internal USB headers. But when I plug the AC adaptor on the board these internal headers are powered on. This problem happens only in this case, if the AC adaptor is plugged and I turn the board on and after I turn it off, these headers are powered off. But if I unplug and plug the AC adaptor the headers are powered on again. The external USB ports is working fine, this problem happens only in the internal headers.
At now I am using the 44 BIOS version, but I tried other versions and happened the same.
Can anyone help me?
