control over the names of these entries. By default the
endpoints will be called \"/dev/usbs0c\", \"/dev/usbs1r\"
and \"/dev/usbs2w\" (assuming all three endpoints are
enabled. The common part \"/dev/usbs\" is determined
by this configuration option. It may be necessary to
change this if there are multiple USB slave-side
devices on the target hardware to prevent a name clash.
