After checking out commit 74658eb and flashing, the USB on the dev kit stops working. The issue still stands at commit 39a1f4b.

I'm using the same devkit. Issue appears when esp_wifi_start() is called with commit 74658eb or more recent, as felixandra mentioned. USB connection (both JTAG and USB serial) is dropped and the host dmesg starts to get filled with the following messages repeatedly:

Commit 0ae4bb8 works correctly.

@nonoo the fix for PHY lib has been merged in https://github.com/espressif/esp-phy-lib/commit/39a1f4b19b9794d7dd9aef741e04244db2da485e, but it requires a change in esp-idf as well. We'll update the related esp-idf issue when the fix is merged.
