How to find USB Flash in Petalinux running on ZYNQ HOST ??




Petalinux is running on ZYBO Z7-20. How to find the attached Flash USB drive ? I don't see USB Flash drive in /dev folder. The jumper JP2 USB Host is short on ZYBO Z7-20.

The following steps have been taken in to account.

1-     Created hardware project in Vivado 2021.1

2-     Added ZYBO Z7-20 board

3-     Added ZYNQ PS in Block Diagram

4-     Apply board pre-set and run block automation

5-     Validate design, Generated output products, HDL wrapper

6-     Synthesis, Implementation, Generate bit stream

7-     Export project with XSA file

8-     Created Petalinux project with template command and set variable OE_TERMINAL = "xterm" in <plnx-proj-root>/project-spec/meta-user/conf/petalinuxbsp.conf 

9- Manually edited system-user.dtsi


/include/ "system-conf.dtsi"
/ {
	model = "Zynq Zybo Z7 Development Board";
	compatible = "digilent,zynq-zyboz7", "xlnx,zynq-7000";
	chosen {
		bootargs = "console=ttyPS0,115200 earlyprintk uio_pdrv_genirq.of_id=generic-uio";
	usb_phy0: usb_phy@0 {
		compatible = "ulpi-phy";
		#phy-cells = <0>;
		reg = <0xe0002000 0x1000>;
		view-port = <0x0170>;
&gem0 {
	phy-handle = <&ethernet_phy>;
/*	phy-reset-gpio = <&axi_gpio_eth 0 0>;
	phy-reset-duration = <10>; */
	ethernet_phy: ethernet-phy@1 { /* rtl8211e-vl */
		reg = <1>;
		device_type = "ethernet-phy";
&usb0 {	
	dr_mode = "host";
	usb-phy = <&usb_phy0>;
&sdhci0 {
&uart1 {
&qspi {
&flash0 {
	compatible = "micron,m25p80", "s25fl128s", "spi-flash";
