Error dding file to usb on Chromebook

I have a Snow Bara samsung chromebook, I want to use USB boot to boot kali linux, without messing up my computer. I used enable_usb_dev_boot to get it to boot from usb, but it has problems when flashing the usb. I created a backup USB, and got a 32 gigabyte usb stick. The kali linux website says for their image, you need at least an 8 gb usb stick. The command that they use is xzcat kali-$ver-exynos.img.xz | dd of=/dev/sdb bs=512k I changed the xzcat name, and path to the corresponding one in my chromebook. I then changed the path of the dd command, to media/removable/USB\ Drive because that was the path of my usb (I checked this). Whenever I use dd it says error this is a directory. I then changed the path to /media/removable/USB\ Drive/ and it said permission denied. I don't see my error. current command is : sudo xzcat home/chronos/user/Downloads/kali-chromebook.img.xz | dd of=/media/removable/USB\ Drive bs=512k
