T440S won't hibernate with USB 3.0

Hello,

On my T440S, since BIOS v2.37.1.13 (with little hope that v2.39 would fix it, I installed it to no avail), I can no longer enter hibernation.
When I try to do so, the red LED blinks multiple times and then the computer immediately wakes up.

 

The event viewer only shows:

The system has returned from a low power state.

Wake Source: Unknown



The workaround is to either unplug all usb devices, or disable USB 3.0 support in the BIOS, which sucks for a 1000e + laptop.
Otherwise, the computer enters a sleep-hibernate-wake up loop which is draining the battery.

When do you plan on releasing an update (BIOS or USB 3.0 driver) to fix this hibernation issue?

Thank you.
