Sorry 'bout that.

I did compilation allyesconfig and allmodconfig with
and without CONFIG_USB_STORAGE_VERBOSE and made
.ko's for that directory only but not a full link.

Looks like it needs EXPORT_SYMBOL_GPL(usb_stor_dbg) in
debug.c.  It takes me quite a while to do a complete
allmodconfig build, but I'll check.
