I'm sorry if I misinterpret what you want, but it sounds like you
need nothing more than an enclosing try/except.

d = Device.open()
try:
    try:
         d.someMethodThatCanRaiseError(...)
         if SomeCondition:
                 raise Error # Error is subclass of Exception
         d.someMethodThatCanRaiseError(...)
         ... lots of other methods on d that can raise Error
    finally:
         d.close()
except:
    # whatever you want here


Is anything wrong with that?
