CISCO1841 is not recognizing HWIC-1DSU-T1

I have a CISCO1841 with IOS 12.4(15)T4 that is not recognizing the EHWIC-1GE-SFP-CU. It has recognized a WIC-1DSU-T1-V2. From what I've seen on the Cisco site the IOS I currently have should be fine for the HWIC-1DSU-T1.

Has anyone else come across this problem?

Have you tried a newer IOS, that versions is pretty old already shouldn't be older than the card but just recently I came across something similar with older PVDMs in a 2811.

based on the hardware that you provided, the minimum release for the hardware that you listed VWIC3-1MFT-T1/E1 is:

12.4(2)T3 

with the latest release being 12.4(24)T3.

I would try and see if you can get the 12.4(24)T3

So seeing that you are running T4, go with T3 and you should be all set. This is what I get back from Cisco site. Also, from the error that you are getting, it appears that the software does not recongize the card. To be clear, you are inserting the card while the router is powered down correct?
