Front USB and Fan not working on RaspberryPi 4 (Buster and Bullseye / 32 and 64 bits)

[therestoftheday]

Hello,

I have tried everything to make front USB and Fan work but none of them are working. I have just bought a DeskPi Pro.

uname -a
Linux raspberrypi 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr  3 17:24:16 BST 2023 aarch64 GNU/Linux

cat /proc/version
Linux version 6.1.21-v8+ (dom@buildbot) (aarch64-linux-gnu-gcc-8 (Ubuntu/Linaro 8.4.0-3ubuntu1) 8.4.0, GNU ld (GNU Binutils for Ubuntu) 2.34) #1642 SMP PREEMPT Mon Apr  3 17:24:16 BST 2023

cat /sys/firmware/devicetree/base/model
Raspberry Pi 4 Model B Rev 1.5

I have tried Raspbian Buster 32-bit version (the one shown here : https://github.com/DeskPi-Team/deskpi/), with install.sh script, Debian Bullseye 32-bit version with install.sh script, and Debian Bulleseye 64-bit version with install-raspbian-64.sh script. Nothing works.

For the fan : deskpi.service seems to work (not the fan) but when I try to make the fan spin at 100%...

Just input the number and press enter.
Your choice:4
You'tve select 100% speed level
Fan speed level has been change to 100%

then ...

NB : When I make a long press on the power button, the fan spins. A short press stops it.

---

For the front USB : The ' dtoverlay=dwc2,dr_mode=host' stuff is correctly added to /boot/config.txt But after (multiple) reboots, the front USB ports have never worked (i tested these ports by plugging a keyboard and a mouse on them).

---

I have wandered through the multiple issues and made different tries, but I am really stuck. At start I thought the 64-bit version Raspbian and the 64-bit version of the deskpiscript were incompatible, but even 32-bit Raspbian version and 32-bit version of the script are not working 'together'. I spent the day trying to make it work, with no success at all. Thanks for your help.

For front USB: Did you try to reassemble Raspberry Pi and the daughter board and make sure the USB-C port connect to the daughter board properly ?

$ uname -a
Linux raspberrypi 6.1.0-rpi8-rpi-v8 #1 SMP PREEMPT Debian 1:6.1.73-1+rpt1 (2024-01-25) aarch64 GNU/Linux

I encountered the same issue.

Upon checking the /boot/config.txt file, I found the following contents:

$ cat /boot/config.txt
DO NOT EDIT THIS FILE

The file you are looking for has moved to /boot/firmware/config.txt

I added dtoverlay=dwc2,dr_mode=host to the end of the /boot/firmware/config.txt file, and after rebooting, the front USB ports and the fan started working.

I used the install-ubuntu-64.sh script for the deskpi installation.

Thanks for your reply ! Well I have returned my Deskpi because at the end i thought there was an hardware problem... So I need to buy, try to install everything (Debian Buster), and change a config.txt file somewhere but not necessarily in /boot/....?

[ani2life]

I found that modifying the /boot/config.txt file on Raspberry Pi OS Lite (64-bit) I installed was ineffective. The correct solution was to modify the /boot/firmware/config.txt file.

please try new script in branch : feature/bookworm 's installation folder.
