I have USB floppy.

Mar 24 00:11:25 HP kernel: usb2_alloc_device:1516: getting device 
descriptor at addr 3 failed!
Mar 24 00:11:26 HP kernel: ugen0.3: <Mitsumi> at usbus0
Mar 24 00:11:26 HP kernel: umass0: <Mitsumi MITSUMI USB FDD 061M, class 
0/0, rev 1.10/2.00, addr 3> on usbus0
Mar 24 00:11:26 HP kernel: umass0:  SCSI over Bulk-Only; quirks = 0x0100

Mar 24 00:11:27 HP kernel: xptioctl: pass driver is not in the kernel
Mar 24 00:11:27 HP kernel: xptioctl: put "device pass" in your kernel 
config file


but,

HP$ grep "pass" /usr/src/sys/amd64/conf/GENERIC
device          pass     # Passthrough device (direct SCSI access)
device          aacp     # SCSI passthrough for aac (requires CAM)
HP$

If I unplug and plug it to the same port:

Mar 24 00:19:12 HP kernel: usb2_alloc_device:1516: getting device 
descriptor at addr 3 failed!
Mar 24 00:19:12 HP kernel: usb2_req_re_enumerate:1434: getting device

Mar 24 00:19:14 HP kernel: uhub_reattach_port:413: could not allocate 
new device!

If I plug it to another port - it detect, but need "pass" driver =)

============
I have USB mouse. If I plug it first time - all OK. If second - to the 
some port:
Mar 24 00:21:45 HP kernel: ugen0.3: <Logitech> at usbus0
Mar 24 00:21:45 HP kernel: ums0: <Logitech Optical USB Mouse, class 0/0,
