FreeBSD bemused by USB card reader

I was playing with a USB card reader and FreeBSD, and I've discovered some 
quirks that I imagine need attention.  The driver involved is umass(4).

The card reader itself has four slots in which various formats of flash 
card can be inserted, and is a USB device.  The quirks are as follows:

1.  If the card reader is plugged in to the USB with no cards inserted, 
the result is a storm of messages, one for each of the four slots, saying 
in effect "Medium not present; Unretryable error".  Ok, kindof, but
given
how hard it tries (more than 80 lines of dmesg output are generated!), I 
think BSD is missing the point (ie, the media may come later...).

2.  Device entry points da0, da1, da2 and da3 are created in /dev without 
any slice or partition subdevices (can somebody please point me to 
documentation which explains when and why I get da0s1 or da0a or da0s1a: 
I'd really like to know at the block device level what's going on
there).

3. When I insert a card into the card reader: no messages are generated, 
and no new devices are generated (so I have to mount the device as da0, 
and can't mount any slices or partitions).
     Of course, there is a workaround here: plugging the card into the card 
reader *before* plugging it into the USB port works, but FreeBSD is 
underperforming here.  For example, OSX has no problem in recognising a 
card being inserted or removed.
     Similarly, removing a card from the reader is also not noticed.

I've tried `camcontrol rescan 0` (or all), as suggested in umass(4), but 
it doesn't change the devices present in /dev, so is clearly *not* 
recognising insertion or removal of cards.

I don't know if this is an issue or not, but `usbdevs` never shows the 
cards, only the card reader.

4. This one is quite interesting: if I reboot with the card reader 
installed with a card in one slot (I was trying to boot off the card; no 
luck) and then remove it: it fails to remove da1, da2 and da3 from /dev. 
When I re-insert the card reader... I get two copies of da1!  Look:
 	# ls /dev/da1*
 	/dev/da1 /dev/da1
Looks well dodgy to me.
 	Ok, tried again (with the card removed), and this time I get two 
copies of da2 and da3 also:
 	# ls /dev/da*
 	/dev/da0 /dev/da1 /dev/da1 /dev/da2 /dev/da2 /dev/da3 /dev/da3
How very very strange.

In case it's of interest, I've attached the output from `dmesg`.

Oh: and here's `uname -a`:

Strange, yes. Surprising, no. 

umass (and USB support is not in the best of shape in FreeBSD. But there
is hope. A re-written USB driver set is currently in development. It's
not even in -current, but the word from a limited number of testers is
that it's a BIG improvement. (Giant free!)

On the down side, umass is not one of the drivers that has been
re-written last I checked. It is by far the most heavily utilized of the
remaining drivers, but is also one of the more complex because of the
huge number of different devices it must work with.

I suspect that little work will be done on fixing the existing driver
unless someone spots an easy bug to fix. (One or two of your problems
MAY fit that category, but I am not familiar enough with the driver to
really have an opinion worth listening to.

I suspect that the new drivers are still a month or two from hitting
-current and I don't know if they will be such that they can be merged
into 6-stable or not. (If they require API or ABI changes, they can't go
into V6.)

If you want to follow this more closely (and maybe get some of your
concerns addressed), you might try subscribing to the freebsd-usb list
and sending details there and sending in a PR on what you've seen.
