hi all,
i have trixbox 2.8.0.4 fully updated, and with b400p inside.

[font=verdana, arial, helvetica, sans-serif]i have tried to follow http://bbs.openvox.cn/viewthread.php?tid=890&extra=page%3D1
and here are results:
1. i created symlinks successfully
2. restarted asterisk with CLI>restart now
3. mISDN scan
1 mISDN compatible device(s) found:
>> BN4S0
4. mISDN config
Writing /etc/mISDN.conf for 1 mISDN compatible device(s):
>> BN4S0
/etc/mISDN.conf already present, saving a backup: /etc/mISDN.conf.bak
5. mISDN start
-- Loading mISDN modules --
>> /sbin/modprobe --ignore-install capi
>> /sbin/modprobe --ignore-install mISDN_core debug=0

with dmesg i see no errors:
a) dmesg after reboot:

b) after mISDN start i see these lines:

now in asterisk shell i cannot find misdn, so after:
CLI> misdn show stacks
i get:" No such command 'misdn show stacks' (type 'help misdn show' for other possible commands) "

with: *CLI> module load chan_misdn.so
