I have a Cisco 2620XM router, and just installed the Cisco WIC-1DSU-T1-V2, but the router doesn't recognize it, saying it has an unknown ID of 0x52. I'm running IOS version 12.2(8)T5 on my router. The documentation for the WIC says it is compatible with the XM series using IOS version 12.2(8)T1, so I would assume that the T5 version is later and would work too.
If the T5 version is not compatible, where might I download the T1 version so I can get this module up and running????
