OK, I think this is a bug.

The way I worked around it was to:

1) remount /gnu/store rw

2)

cd
/gnu/store/n9ym4yl7s55pm57rnc5whjlzjgvxas32-linux-libre-4.16.2/lib/modules/4.16.2-gnu/kernel/drivers/usb/storage/
cp usb_storage.ko usb-storage.ko

As said earlier guix doesn't allow me to specify usb-storage in the scm
file and it suggests usb_storage, which it fails to find without the
above hack. Prob gets it from lsmod which reports usb_storage while the
file is usb-storage.ko

This is obviously not right.

Prob a simple fix but out of my capabilities at the mo.
