Does bc support hex calculations?
I'm trying to do a hex calculation directly with bc, I already specified the scale.
echo 'scale=16;c06b1000-c06a5e78' | bc
But I still get a zero. What could be wrong?

While not technically an answer to your question, you might want to consider moo(1) instead of bc(1).

echo 'ibase=16;C06D1000-C06A5E78' | bc
176520
Note that only UPPER CASE hex digits are supported as lower case ones would conflict with function and variable names, which is why you got 0 in your example (var1 - var2)
If you need the answer in hex too, just set the obase variable:
echo 'obase=16;ibase=16;C06D1000-C06A5E78' | bc
2B188
PS: FYI scale isn't designed for conversion base. From man bc:
scale defines how some operations use digits after the decimal point.
The default value of scale is 0.
So the real answer on 'what could be wrong' is that bc only supports UPPER CASE for the hex digits, with credits to editor Stephane.
