Below output of above two commands on my system

root at raspberrypi:~# ls -1 /sys/block/sda/device/../../../../{bcd,id}*
/sys/block/sda/device/../../../../bcdDevice
/sys/block/sda/device/../../../../idProduct
/sys/block/sda/device/../../../../idVendor
root at raspberrypi:~# find /sys -name idVendor
/sys/devices/platform/soc/3f980000.usb/usb1/idVendor
/sys/devices/platform/soc/3f980000.usb/usb1/1-1/idVendor
/sys/devices/platform/soc/3f980000.usb/usb1/1-1/1-1.1/idVendor
/sys/devices/platform/soc/3f980000.usb/usb1/1-1/1-1.1/1-1.1.3/idVendor
/sys/devices/platform/soc/3f980000.usb/usb1/1-1/1-1.1/1-1.1.1/idVendor
/sys/devices/platform/soc/3f980000.usb/usb1/1-1/1-1.2/idVendor
root at raspberrypi:~#

What's inside these files are as below

root at raspberrypi:~# cat /sys/devices/platform/soc/3f980000.usb/usb1/idVendor

My understanding I do have mentioned files in my system.
