xhci USB devices keep on resetting (autosuspend issue?)

Hi,

I'm having massive resetting issues with two "superspeed" xhci devices (webcams): after some time of usage, which seems fully random, the devices keep on disconnecting and reconnecting like crazy.

I suspect it might have to do with the USB autosuspend feature being active (by default??).

What needs to be done to unconditionally disable USB autosuspend on all USB devices (or at least on the two cams)? What would be a good way in arch to achieve this?

Thanks!

"-1" will deactivate it, nb. that userspace tools can alter this all the time and more sepcific entries for the device will shadow the global value.
