/dev/lirc0 not found

I am using a Raspberry Pi 1B running Raspberry Pi OS (Trixie) with a 
TSOP38238 infrared receiver to be able to capture the codes for an IR 
remote that is not supported by the Amazon Fire stick. LIRC was 
installed from the distribution repository (v 0.10.2). The configuration 
is setup based on the following page by Gordon Turner ( 
https://blog.gordonturner.com/2017/10/29/linux-infrared-control-part-1-receive-ir/ 
). Though I can see 3.3VDC at both the lead for power and the lead for 
input, the LIRC device (/dev/lirc0) is not present after boot up. Not 
sure how to proceed.
