Does your Ampak module use Cypress or Broadcom/Avago silicon? Many of them use Broadcom/Avago. If that's the case, they'd provide support.
I'm not sure, but given the age of my device I'd expect that it is Broadcom. However, I'm just consumer and therefore getting support from either Broadcom or AMPAK is difficult.
The reason I am reporting this here is that it started happening when upgrading to the Cypress firmware. The old Broadcom firmware provided in linux-firmware is working fine except for P2P. Given that the updated Cypress firmware is now shipped in all Linux distributions, no matter if Cypress or Broadcom silicon, I was hoping you could at least provide some sort of support for that closed-source binary.
