Hi, i´ve a USB port problem.

I´ve already update all the lenovo drivers both automatically and manually and it didn't work. The PC keeps blocking me the USB ports.

When i was looking for the solution, we tried to disable the cortex agent and after a restart the issue stops, the PC automatically detect the USB device and there´s no error in the driver.

When the cortex agent was disabled, I tried to update again the USB drivers, but the lenovo utility says all was up to date.

The problem only appears on M70Q CPU connected via AIO mode (inserting the CPU behind the monitor) to a ThinkCentre TIO22 Gen5 Touch - Type 12N9 monitor.

i hope someone can helps me
