Does this device have a button to enable it? Does it help pressing that
button?
One idea is to not power down the port which obviously gives the device power
on failures.
Hi,
Its a mini-pciExpress card that is designed to be inside a

similar devices I have dont exhibit this behaviour so it seems to be
quirky to this particular model.
Here is the card and board
