Hi:
In your system ,when i run the command, I found the reason why you can not configure B200P card.
[/usr/src/asterisk]->dahdi_hardware
pci:0000:16:00.0 wct4xxp+ d161:0410 Wildcard TE410P (2nd Gen) driver should be 'wcb4xxp' but is actually 'hfcmulti'
pci:0000:16:02.0 wcb4xxp+ 1397:08b4 OpenVox B200P
The module "hfcmulti" is used by mISDN. So, if you use dahdi,you must uninstall mISDN from your system.
====================================
[/usr/src]->modprobe -r hfcmulti
[/usr/src]->modprobe dahdi
[/usr/src]->modprobe wcb4xxp
[/usr/src]->dahdi_genconf
[/usr/src]->dahdi_cfg -vvv
DAHDI Tools Version - 2.3.0
