Not really familiar with the PIC32, but do you have some kind of logs for it? The PIC32 should get the usual power sequence signals from the PCH and acknowledge them before the host gets back to the reset vector. I had a similar case in the past where the PCH repeated sending the power sequencing signals but the EC (in your case PIC32) failed to acknowledge them (which resulted the Host to get stuck). I know you said that you tested the same setup with slimbootloader, but that's the best I can currently come up with.
