pk2cmd linux port under FreeBSD

[Xiaofan Chen]

I have tried pk2cmd linux port under FreeBSD. It is not working with the stock
USB stack (was using 6.2 stable and now 7.0 beta). I need to get the
new alternative USB Stack from Hans Petter Selasky (HPS).

To get the HPS USB stack for FreeBSD, follow the following instruction.

svn --username anonsvn --password anonsvn checkout svn://svn.turbocat.net/i4b
cd i4b/trunk/i4b/FreeBSD.usb
make S=../src package
make install
Follow the "make help" instructions.

One patch required is the file "ugen.c". In the function
"ugen_open_pipe_read()",
find the line "case UE_INTERRUPT:" and then some lines further down
you will find:
/* first transfer clears stall */
sce->read_stall = 1; //---> Chaneg this to "0".
Then recompile and install the "ugen" module and/or kernel.

Why do you need to run as root?

I have not yet setup the udev rules under FreeBSD. I will do it later now
that I just cleared a bit of the mess after updating to FreeBSD 7.0 Beta.

Thanks for asking.

Done. And I found a great resources about Linux/BSD USB device rules.
I also learned that there is no udev under FreeBSD. It is called devfs rules.

http://www.gphoto.org/doc/manual/permissions-usb.html

Steps:
1. Create group "usb" and add the user name to it.
2. Edit /etc/devfs.rules to add the following lines.
[usb_devices=10]
add path 'ugen*' mode 0660 group usb
add path 'da*s*' mode 0660 group usb
3. Edit /etc/devfs.conf and add following lines: [Confirmed that this
is necessary]
perm usb0 0660
own usb0 root:usb
perm usb1 0660
own usb1 root:usb
4. Edit /etc/rc.conf and add the following lines:
# Set the default devfs ruleset.
devfs_system_ruleset="usb_devices"
5. Activate the changes by running the following command (no reboot required):
host:~# /etc/rc.d/devfs start

6. Testing:
===[mcuee] ~/Desktop/build/pk2cmd4bsd # ls -la /dev/ugen0*
crw-rw---- 1 root usb 0, 138 Nov 1 22:31 /dev/ugen0
crw-rw---- 1 root usb 0, 120 Nov 1 22:56 /dev/ugen0
