What is the problem? (only list ONE problem per report)

Hello, I recently developed my own HW2 internal install for the Dreamcast. I have followed all of the application notes from your design doc (they are quite thorough) with the only deviation being that I used a custom circuit for port detection (which works well)

All of my Dual-sense, PS3 controllers connect, and my other switch controllers (Power-A pro controller look-alike) connect. However, I can't get my SN30 Pro+ to connect in any mode. I have tried 24.10 and 25.01 firmwares. Interestingly, I'm able to get this controller to connect on two other Blue retros I have, both are running HW1 firmware, one of them is using the same ESP32 Dev-board I used for my HW2 installation (https://www.amazon.com/dp/B08DQQ8CBP?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1)

What did you expect to happen?

SN30 Pro+ should connect in Xinput or switch mode (as it does with HW1 installs)

Connecting VN to 3.3v resolved this issue, now the port 1 LED blinks when the console has no controllers connected. I wasn't aware this had to be connected directly to the 3.3v rail when the "optional" power features weren't being utilized. I'm not sure why everything but the 8bitdo works LOL. I just re-read the design doc and I don't think it's entirely clear. Luckily I had a jumper on my PCB because I thought it might be necessary.
