I've now compiled a kernel with USB_DEBUG, and I also added
a few lines of debugging printfs myself.  This is what I get:

uscanner1: <vendor 0x03f0 product 0x0305, class 0/0, rev 1.00/0.00, addr 2> on uhub0
usbd_set_config_no: 1
usbd_get_config_desc: confidx=0
usbd_get_desc: type=2, index=0, len=9
usbd_alloc_xfer() = 0xc3b05200
usbd_transfer: xfer=0xc3b05200, flags=2, pipe=0xc3fda380, running=0
usbd_dump_queue: pipe=0xc3fda380
usb_insert_transfer: pipe=0xc3fda380 running=0 timeout=5000
usb_add_task: task=0xc3b05378
usb_task_thread: woke up task=0xc3b05378
usb_schedsoftintr: polling=0
usb_transfer_complete: pipe=0xc3fda380 xfer=0xc3b05200 status=15 actlen=0
usb_transfer_complete: repeat=0 new head=0
usbd_start_next: pipe=0xc3fda380, xfer=0
usbd_free_xfer: 0xc3b05200
usbd_get_config_desc: usbd_get_desc() --> usbd_status 15
usbd_set_config_no: index 0 --> usbd_status 15
uscanner1: setting config no failed [usbd_status=15]
device_attach: uscanner1 attach returned 6

usbd_status 15 is USBD_TIMEOUT.

I wanted to run udesc_dump, so I compiled a kernel without
uscanner so the device would attach to ugen.  However, I get
this (after a few seconds):

uhub_explore: usb_new_device failed, error=TIMEOUT
uhub0: device problem (TIMEOUT), disabling port 2

So I get a timeout again.  The problem doesn't seem to be
uscanner-related, but more low-level.
Any ideas how to proceed?

Best regards
   Oliver

PS:  I'm pretty sure the scanner is not defective.  Also,
the USB controller is fine; a flash stick plugged into the
same port is working perfectly fine.
