Thank you for your reply.
As already said, I'm not putting the AK1 in sleep mode, I'm completely turning off the AK1...
I continue to think that you should implement differently the USB power management.
For example you could decide to power some USB port when AK1 is off, and some other usb port could be not powered...
it's not so difficult !!!
It's not impossible !!!
It's safer !!!
It's more efficient !!!
it's more reliable !!!
Please evaluate this change request, I'm really upset for this issue...
