failed to read packet header

[leorasy]

Hello, problem already seen here but with no public solution so I have to ask.

I used a CP2102 and a atmega32u4, connected as shown here: smash karts
https://gimx.fr/wiki/index.php?title=DIY_USB_adapter

Then I loaded the firmware using gimx 8.0 with emug29ps4, made my config to use my sim hardware as a g29. Everything seemed good so far.

I plugged it in my started ps4, disconnected the DS4 and started gimx launcher with my config and got this:

Code: Select all

option globale -c avec valeur `LogitechG27v1.61.xml'

As mentionned in the wiki, I tried inverting rx/tx, but it changed nothing. I have only one port detected (and none if I disconnect it) so no possible error here too. Last suggested thing to do is to verify the firmware. If I click on verify in gimx launcher it just tells me "joystick not found".

edit: my config is a Xeon v3 on windows 10, 32gb of ram and I don't know if there's anything else useful

Hopefully the solution is simple.

The error message "failed to read packet header" typically appears in applications that use network communication or USB/serial data transfer, such as GIMX or other emulation tools. It means the software was expecting data (a packet), but couldn't read the beginning (the "header") properly.
