You can use Pattern Matching for Switch LOP, and it already allows usd_* expressions.

In python, strings are usually enclosed in single or double quotes and their number must be balanced. The script finds another single quote in your HDA's path that is in no way unbalanced. If possible, it is better not to use special characters in the path at all, including whatespaces, and replace them either with underscores or dashes.

Bad update this build still has this bug. Please update to the latest stable build.
