Enable USB mass storage in kernel

[7wells]

Is your feature request related to a problem? Please describe.
After following the instructions at https://github.com/dorssel/usbipd-win/wiki/WSL-support it is still impossible to mount the device to the WSL2 distro's filesystem.

Describe the solution you'd like
If the kernel had USB mass storage enabled, the problem would be solved AFAIK.

Describe alternatives you've considered
None

Additional context
For USB mass storage support, in drivers/usb/storage:
USB_SUPPORT [=y]
USB_STORAGE [=y]

For NBD support (to run qemu with image), in drivers/block:
BLK_DEV_NBD [=y]

Thanks for your kind consideration!

@7wells you didn't specify a kernel version. In 5.15.146.1 some options are enabled already:

elsaco@texas:~$ zgrep USB_SUPPORT /proc/config.gz
CONFIG_USB_SUPPORT=y
elsaco@texas:~$ zgrep BLK_DEV_NBD /proc/config.gz
CONFIG_BLK_DEV_NBD=m

Only USB_STORAGE is not set. That could be built as a module, too. Notice how latest WSL kernels support module loading/unloading.

Even with USB_STORAGE enabled you won't be able to mount/unmount USB drives in WSL. The only option available is USB over IP.

Thank you so much! Indeed I failed to first check what the current version has enabled. I will check the USB over IP possibility you kindly mentioned.

I guess my question can be closed, right?
