What does usbconfig say?
Ok, now I have laptop with fresh CURRENT. Its usbconfig says

Can you enable host controller debugging:
hw.usb.xhci.debug=17
hw.usb.ehci.debug=17
hw.usb.uhci.debug=17
hw.usb.ohci.debug=17
900Kb of dump from first connect to last disconnect is here:

Hi Lev,
ster kernel: xhci_roothub_exec: port status=0x000202a0
May 7 14:39:08 hamster kernel: xhci_roothub_exec: type=0x23 request=0x01
wLen=0x0000 wValue=0x0010 wIndex=0x0002
May 7 14:39:08 hamster kernel: xhci_roothub_exec: UR_CLEAR_PORT_FEATURE
May 7 14:39:08 hamster kernel: xhci_device_state_change:
May 7 14:39:08 hamster kernel: ugen0.6: <PPC Offline UPS> at usbus0 (disconnected)
The value reported by XHCI PORTSC, 0x000202a0, indicates:
BIT5-8 : 5) Link is in the RxDetect State
BIT9 : Port Power (PP) – RWS. Default = ‘1’
BIT17 : Connect Status Change (CSC)
It is clear that the XHCI controller has received a disconnect event
from the UPS.
Can you check the other OS'es where this supposedly does not happen, if
the UPS device attaches to the XHCI or EHCI controller?
Did you start any driver for the UPS?
