I’m building the Alex Taradov’s USB Sniffer and after facing some issues with FPGA short-circuit I decided to start from begging soldering a new board only with USB Host parts (mainly the CY7C68013A chip).

After some small issues with USB-C soldering it start to give some signal of life:

Error: incorrect FPGA IDCODE (0xffffffff)

I think this last error message is because I didn’t solder the FPGA yet. Stay tuned!
