Hans,

I have a similar problem where sometimes my USB mouse won't get attached and
sometimes it will. For me it seems that the behavior depends on USB port that the
mouse is attached to. But maybe I have a different problem, maybe some ports are
indeed "bad".

Here is how it looks when the mouse fails to attach:
usb_alloc_device:1588: set address 2 failed (USB_ERR_TIMEOUT, ignored)
usb_alloc_device:1626: getting device descriptor at addr 2 failed, USB_ERR_TIMEOUT!
usbd_req_re_enumerate:1539: addr=2, set address failed! (USB_ERR_TIMEOUT, ignored)
usbd_req_re_enumerate:1553: getting device descriptor at addr 2 failed,
USB_ERR_TIMEOUT!
usbd_req_re_enumerate:1539: addr=2, set address failed! (USB_ERR_TIMEOUT, ignored)

ugen0.2: <(null)> at usbus0 (disconnected)
uhub_reattach_port:435: could not allocate new device!


Here is success:

Not sure what kind of usbconfig output would be useful.
