FC2 test1 USB hotplug issues

[Sandy Pond]

FC2 test1 USB hotplug issues.  I'd like help as to what deserves to go
to bugzilla. 

I have a USB 6 in 1 card reader (IN-WIN iAPP HS-CF) which gives spurious
output in /var/log/message about once and hour;

1.  It tends to eat up USB and SCSI addresses;

2.  Seems that the /etc/hotplug/scsi.agent doesn't find type in sysfs
type file;

Even though;

$ cat /sys/devices/pci0000:00/0000:00:02.2/usb1/1-3/1-3:1.0/
host2/2:0:0:0/type
0

I get;

3.  I seems the usb_storage is dependent on having an available hardware
floppy controller.  If I turn off the on-board hardware floppy
controllers in the BIOS I get this in /var/log/messages as the spurious
message;

Although I have yet to try this card reader.
