echo "Copy the above to the root of your  USERPROFILE on the Windows sdie then Add in the [wsl] section of your .wslconfig the following, doubling all
kernel=c:\\users\\username\\wsl-$WSLKERNEL

Then run wsl --shutdown from Windows, wait a minut or so and star wsl again. Once you have your usb device passed you should see the storage device if not, try on the wsl side: modprobe usb-storage; modprobe uas"

This made it so easy to add USB mass storage support, thank you!!.

Side note, I had to make a few changes:

line 4 export CHECKOUT_DIR="linux-msft-wsl-$WSLKERNEL"
line 6 git clone https://github.com/microsoft/WSL2-Linux-Kernel.git --depth=1 -b $CHECKOUT_DIR $WSLKERNEL

Also, I had to increase the WSL memory from 4GiB to 6GiB because pandoc kept getting OOM killed
