Not sure if this is a bug or quirk of my Alix box's hardware or the modem, but with a recent RELENG_8, I get the following errors at bootup time with the attached usb modem

usb_alloc_device: set address 3 failed (USB_ERR_TIMEOUT, ignored)
usbd_setup_device_desc: getting device descriptor at addr 3 failed, USB_ERR_IOERROR
usbd_req_re_enumerate: addr=3, set address failed! (USB_ERR_IOERROR, ignored)
usbd_setup_device_desc: getting device descriptor at addr 3 failed, USB_ERR_IOERROR


What are these, and are they "normal" or do I need to tune something ?

a boot dmesg with hw.usb.debug=1 is at http://www.tancsa.com/usb-error.txt along with usbconfig's verbose output
