Looks very similar to the problem I was having on my 8330. I did three things
that made it work:
(1) Run it under debug. Put a breakpoint at Usb::Device::Write and loop
through. You can just run to the breakpoint, then continue to run again. Each
time it writes it will pause.
(2) If 1 works, try inserting a sleep at the top of write for 250000 micro
seconds. On linux it's defined in unistd.h and is called usleep. I have a
FreeBSD system in a VM and will check when I'm back in front of it
(3) My end solution was to put the sleep at the end of the usb_clear_halt call
which solved my device hangup.
Since you have an 83xx device your comment is very interesting because it
duplicates the "device lockup" behavior I was seeing and the same with the
"entering desktop mode" (but never getting there)

Subject: [Barry-devel] btool/bjavaloader both hang on FreeBSD,
but pppob works fine
The main utility I wanted to use from barry was pppob, so that I could tether
my FreeBSD machine to my Curve 8320. This works fine. I didn't really have
any burning need for the other tools, so I pretty much ignored them.
But then I decided to try btool just for kicks, and I found that it just seems
to hang. It can identify my Blackberry and read its PIN, but after trying to
switch into desktop mode, it just gets stuck.
I put a copy of the debug out from btool here:
http://www.freebsd.org/~wpaul/bb/btool.txt
This is from running btool -z -v -t. At the end, it seems to receive one block
of data back from the Blackberry, but then nothing else happens. I have to ^C
the program, or else it will time out and exit on its own after a minute or
so.
Also, once this happens, it seems to put the Blackberry in a strange state,
and I have to unplug/replug the USB cable to make it work properly again. The
odd behaviors I've seen are:
- After I run btool -t the first time, running btool again fails to talk
to the device at all: it can't read the device type or anything. If I run
btool a _third_ time, it gets to the point where it requests Desktop mode
again, but this time it there is no response.
- After I run btool -t the first time, btidentify also time out. If I run
btidentify a subsequent time, it works.
- After I run btool -t the first time, pppob will never work again, no matter
how many times I try it: I have to unplug/replug the Blackberry, then pppob
will work.
I don't have a Linux system handy, so I don't really know what a successful
debug output looks like, so I can't tell what could be going wrong.
One thing that I noticed is that the BSD port of libusb does not support the
usb_clear_halt() method (it's a no-op). I modified usbwrap.cc to use
usb_control_msg() to issue a clear halt command directly, but this didn't
help matters, so I don't think this is the problem.
Anyone have any idea what could be going wrong here? I'm using the latest code
from cvs. It builds ok, and pppob runs fine, as does btidentify. But neither
of these require Desktop mode to work.
During my experiments with the Blackberry via bluetooth, I stumbled onto the
Desktop bluetooth descriptor -- I was looking for the dialup networking
descriptor and connected to the wrong one by mistake. I noticed that when I
did this, a message came up on the Blackberry's screen indicating that
Desktop mode was active. I don't know if it matters, but I have never seen
this screen come up when trying to use btool.
