Summary:                    [patch] FXS Module detection fails
Description: 
The portion of the wctdm24xxp driver that does a check of reg1 to ensure
that it has a value of 0x88 causes the driver to fail to load for my fxs
modules. The card and modules that I have were purchased on Ebay. The cards
I have return a value of 0x08 during the module detection phase causing the
driver to not recognize my FXS modules. The cards work find with all
versions of DAHDI/ZAP that were released prior to the inclusion of this
code in the driver. Patching the driver to allow either 0x88 or 0x08 allows
me to use DAHDI version 2.4.0 with no issues.

This patch is not for Asterisk. It is for the wctdm24xxp driver included in
the dahdi-linux package. The card I have is the TDM410P which requires the
wctdm24xxp driver. If you do indeed have the TDM400P, it uses the wctdm
driver which does not seem to include the piece of code that kept my FXS
modules from being recognized.

If you are using the wctdm24xxp driver, the file that needs patched is in
the drivers/dahdi/wctdm24xxp directory. You will need the dahdi-linux
source which can be downloaded from
http://downloads.asterisk.org/pub/telephony/dahdi-linux/releases. The card
I am using was purchased from an Ebay vendor named Chinaroby.
