Hello, I purchased a DK005 Quad SSD SATA HAT kit, and this is already the second unit that does not work. There is no dmesg output, and it also does not appear in lsusb. Supplying 12 V power makes no difference, and it is not detected on a different Raspberry Pi 4 either. The USB bridge was, of course, connected. Upon inspecting the PCB, it appears that diodes or jumper links are missing, as well as a 3.3 V voltage regulator for the two USB-to-SATA controllers.
Send it back to the shop where you bought it and make sure you get your money back.
Also a HAT or USB for storage will easily get you in trouble (again), certainly with RPI4 and its separate VIA USB chip. If you want to operate SATA storage, make sure you have or get a computer that has SATA working off-the-shelf, so implemented/tested already by the vendor (Radxa).
Hey, not sure if it is too late. I had the same issue and the same board with those components missing. I eventually figured out that it is because of the gpio version. I got it work by downloading the new version of rockpi-quad. The code is like
Install required tools
sudo apt install -y git i2c-tools python3-pip
Build and install Radxa Rock Pi Quad support package
cd ~
git clone GitHub - radxa/rockpi-quad: Quad SATA HAT for RPi 4 and rock 4se · GitHub
cd rockpi-quad
dpkg-deb --build rockpi-quad
sudo apt install ./rockpi-quad.deb
Reboot to activate hardware configuration
sudo reboot
