Да, кстати сегодня проводил уборку в офисе и споткнулся через плату от Lenovo M73p.
Тоже порт 15, и всё ок.
USBTreeView тоже упоминает этот косяк на странице описания:
Цитата:
Intel Series 8 xHCI Controller
Here we have a bunch of yellow exclamation marks on a Intel Series 8 xHCI controller on a Asus H81-Plus board. Its ports 11 to 15 have a connection status 3 "Device general failure" which leads to the yellow exclamation marks in the tree view.
Intel's xHCI controllers are quite flexible and need a correct initialization by the mainboard's BIOS. I don't know this is Intel's or the BIOS maker's fault. As long as all physical ports work as expected this is a cosmetic problem.
