    Well, the devices is attached to uhid driver if I turn on
    USB_DEBUG (and hw.usb.*.debug to 1). I get the
    following debug messages:

kernel: uhub_explore: status change hub=1 port=2
kernel: usbd_new_device bus=0xc163c000 port=2 depth=1 speed=1
kernel: usbd_new_device: adding unit addr=2, rev=110, class=0, subclass=0, 
protocol=0, maxpacket=8, len=18, speed=1
kernel: usbd_new_device: new dev (addr 2), dev=0xc1841200, parent=0xc1621e00
kernel: usbd_probe_and_attach: trying device specific drivers
kernel: usbd_probe_and_attach: no device specific driver found
kernel: usbd_probe_and_attach: looping over 1 configurations

kernel: usbd_set_config_index: (addr 1) cno=2 attr=0xe0, selfpowered=1,

FW:q3, rev 1.10/0.06, addr 2, iclass 3/0
kernel: usbd_do_request: status = 0x0000

    Without debug, I get just:
 kernel: ugen0: American Power Conversion Back-UPS CS 350 FW:807.q3.I USB 
FW:q3, rev 1.10/0.06, addr 2
