This was added a long time ago in 75abee206d1a575aa98a486d043c94d64df432c1 when USB host support was added to the stm (now stm32) port, and when this pyexec code was actually part of the stm port. It's unlikely to work as intended anymore. If it is needed in the future then generic hook macros can be added in pyexec.
