I write data to host using a usb hid.

The following is the script for hid.

#!/bin/sh

usb_id=1
case "$1" in
  start)
        #1 mount configfs
        mount -t configfs none /sys/kernel/config

        #2 create hid mouse gadget
        cd /sys/kernel/config/usb_gadget
        mkdir g1
        cd g1

        #echo "0x0103" > idVendor
        #echo "0xA213" > idProduct

        echo "0x0483" > idVendor
        echo "0xA058" > idProduct

        mkdir strings/0x409

        echo "0123456789ABCDEF"         > strings/0x409/serialnumber
        echo "TEST ENG Co.,Ltd."    > strings/0x409/manufacturer
        echo "HID_CAT"                  > strings/0x409/product

        sleep 1

        #3 create cfg
        mkdir configs/c.1
        mkdir configs/c.1/strings/0x409

        echo "HID" > configs/c.1/strings/0x409/configuration
        echo 0xc0  > configs/c.1/bmAttributes
        echo 500   > configs/c.1/MaxPower

        sleep 1

        #4 create function
        #hid mouse
        mkdir functions/hid.usb0

        echo 0 > functions/hid.usb0/subclass
        echo 0 > functions/hid.usb0/protocol
        echo 64 > functions/hid.usb0/report_length

        # Write report descriptor
        #hexdump /sys/kernel/config/usb_gadget/g1/functions/hid.usb0/report_desc

        echo -ne "\x06\x06\xFF\x09\x01\xA1\x01\x85\x4F\x09\x4F\x15\x00\x25\xFF\x75\xF8\x95\x02\xB1\x82\x85\x4F\x09\x4F\x91\x82\x85\x49\x09\x49\x15\x00\x25\xFF\x75\xF8\x95\x02\x81\x82\x85\x49\x09\x49\xB1\x82\xC0" > functions/hid.usb0/report_desc
        
        sleep 1

        #5. hid mouse
        ln -s functions/hid.usb0   configs/c.1

        sleep 1

        #8. start gadget
        my_udc=$(echo `ls /sys/class/udc/` | cut -d ' ' -f ${usb_id})
        echo ${my_udc}

        if [[ ${my_udc} != "" ]]; then
                echo "${my_udc}" > /sys/kernel/config/usb_gadget/g1/UDC
        fi

        sleep 1
        ;;
  stop)
        echo "" > /sys/kernel/config/usb_gadget/g1/UDC
        rm     /sys/kernel/config/usb_gadget/g1/configs/c.1/hid.usb0/
        rmdir  /sys/kernel/config/usb_gadget/g1/configs/c.1/strings/0x409/
        rmdir  /sys/kernel/config/usb_gadget/g1/configs/c.1/
        rmdir  /sys/kernel/config/usb_gadget/g1/functions/hid.usb0/
        rmdir  /sys/kernel/config/usb_gadget/g1/strings/0x409/
        rmdir  /sys/kernel/config/usb_gadget/g1/

        umount /sys/kernel/config
        ;;
  restart|reload)
        ;;
  *)
        echo "Usage: $0 {start|stop|restart}"
        exit 1
       
esac

exit $?

When I try to write data to host like the following command,

echo -ne "\x97\x77" > /dev/hidg0

the below error message displayed.

[ 555.161464] configfs-gadget gadget: usb_ep_queue error on int endpoint -11 sh: write error: Resource temporarily unavailable

But the read operation is passed.

What should I check to solve this problem?

Thanks.
