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.

I have the same problem that asterisk 1.4.36 doesn't detect the fxs module on the TDM400P, I have tried this patch and it asked me which file to patch, I checked my system and there is no file called base.c to patch.

Please can you verify which file is meant to be patched with this patch.

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.

Is there a reason that this patch has been removed from the SVN source?
By: Tzafrir Cohen (tzafrir) 2011-02-06 03:57:08.000-0600

From what I see, this code was removed in rev. 9720 ("wctdm24xxp: Remove code for unsupported modules.")

The card I have is NOT an S100M. I have S110 type modules. The patch I submitted earlier still compiles and works fine with my card and dahdi version 2.4.1.1. This patch was not specific to S100M modules.
