For mouse/keyboard i would suggest use GIMX.

g29emu is at the moment only working as G29 wheel emulator. No DS4 emulation yet.
it could be possible in the future, but i have no plans to do so.

The Trinket M0 contains an ATSAMD21E18. The datasheet states only one USB device in peripheral mode. Still one host usb missing.

This one has got 2 usb Hosts though.
but i guess that it wouldnt be enough as you'd for the time being, need 3 ports, one as device and 2 as hosts
for the ds4 and wheel/or whatever.

Also if you get a bluepill as a substitute for the pro micro + the mini host shield + the 2/3 port hub, that's ultimately less than 10$ (could also be cheaper without substituting)

Datasheet states:

Advanced connectivity
-USB 2.0 full-speed device/host/OTG controller with on-chip PHY
-USB 2.0 high-speed/full-speed device/host/OTG controller with dedicated DMA, on-chip full-speed PHY and ULPI

Looks plausible however you still need a HUB (or integrate one on your PCB)

However, a better solution would be to use STM32F446RCT6 which costs about 7 euro's and integrate in on a custom PCB together with some connectors.


STM32F446RCT6 Advanced connectivity
– USB 2.0 full-speed device/host/OTG controller with on-chip PHY
– USB 2.0 high-speed/full-speed device/host/OTG controller with dedicated DMA, on-chip full-speed PHY and ULPI
– Dedicated USB power rail enabling on-chip PHYs operation throughout the entire MCU power supply range

I have an idea to design a PCB with the following components

- STM32F4 with 2 USB ports, LQFP64 (or LQFP48/32 if possible)
- Texas Instruments TUSB 2036 USB 2/3-HUB 3,3 V, LQFP-32 (costs only €1,47 each)
- Two USB Type A receptables for connecting wheel/auth device
- One USB-C/micro-usb connector for connecting to PS4

Idea is to have as less components as possible and be able to solder by hand (no stencil needed)

STM32 has completely different CPU architecture and needs new FW

True, its Cortex M4 vs AVR 8bit.
I wont say there are no differences, but most of them are HAL.
Of course there are lots of benefits like systick timer, lots of irq, PLL.

I see no reason yet it will not work (have worked with many m0,m3 and m4's before)

Thijs, after finding the link below. i thought that maybe, we could bypass the auth by dropping the connection, for a very short time every 8 minutes or so.
again its just a thought, that might not be plausible irl.

it seems like the alternative systems, do infact utilize this tactic.
