Hi Dmitry, > Semi-random suggestion, but could you please try using > clk_regmap_phy_mux/clk_regmap_phy_mux_ops for USB pipe clk src? Which specific clock are you refering to? I'm not very familiar with those, in the device tree I'm seeing "pipe" clocks for usb_0 and usb_1 phys, but not for usb_2, which is the one that's causing issues. Best, Adrien

Looks like that might be the cause indeed. The arm64 defconfig has the PHYs built as modules, but with either CONFIG_PHY_QCOM_QMP_USB=y or CONFIG_PHY_QCOM_USB_SNPS_FEMTO_V2=y, the controllers initialize properly all the time.

Could you please try adding the 'qcom,select-utmi-as-pipe-clk' property to the usb_2 host node and running the test again?
