ESP32-P4 iot modem A7670E USB

[dgnice]

Hello everyone,
I had an ESP32-S3 wareshare SIM7670 and IoT modem, everything worked fine.
I migrated everything to an ESP32-S3 with a SiM7670E module via USB OTG, and everything worked (internet, websocket and camera)...
So I decided to upgrade to an ESP32-P4 with the same 7670E USB module, changing the version to >1.0.0 (no more USB endpoint, but CDC, a bit of a pain , but necessary to use ESP32P4 ), and now I can't get PPP working.
Communication USB is working, but the modem stays on WAIT IP...
Has anyone ever used a USB modem with a P4 ?
