I am trying to setup 0.4.1 on a raspberry pi V1B. I had to modify the config file before my monitor would display anything. The mod was to comment out the following lines:
#hdmi_force_hotplug=1
#hdmi_drive=2
#gpu_mem_256=64
#gpu_mem_512=200
The display now worked and the initial setup screen was displayed. Unfortunately neither the USB keyboard or the wireless mouse works therefore I cannot move through tthe setup procdedure.
Any help would be appreciated. Thanks.

None of those config changes would likely affect USB input devices. First off, PHT no longer supports a mouse interface... so most likely your keyboard has an issue. Power can definitely be a problem on USB devices.
I would suggest you try a different USB keyboard or try booting another OS and check your hardware works.
If you want to identify the specific issue, you can look at your dmesg log for errors also.
Just out of curiosity, what caused you to change your config.txt? If it was a HDMI to DVI adapter this is the only line that matters:
hdmi_drive=2
