I think you have > only USB 2.0, that's why I question the suffix. > I cross checked the schematic of v920 SADK, this is a combo PHY which support USB-3.0 as well. @ Pritam Schema should capture all the supplies including USB-3.0, similar to GS101 (which has USB2.0 and DP combo). So that would be as below: dvdd075-usb20-supply vdd18-usb20-supply vdd33-usb20-supply dvdd075-usb30-supply vdd18-usb30-supply please cross check the supply at your end and do the needful. > > Best regards, > Krzysztof
