Looks like a typo in Device::USB::DevConfig synopsis: nNumInterfaces is
referenced only there.
On the other hand bNumInterfaces is documented later in the man page and used
in the test files:
$ ack bNumInterfaces
t/15-usb_dev_configuration.t
32: qw/wTotalLength bNumInterfaces interfaces bConfigurationValue
48: is( $cfg->bNumInterfaces(), scalar @{$cfg->interfaces()},
"$filename:$cfgno: interface count" );
USB.pm
918: hashStoreInt( hash, "bNumInterfaces", cfg->bNumInterfaces );
924: list_interfaces( cfg->interface, cfg->bNumInterfaces )
lib/Device/USB/DevConfig.pm
79:=item bNumInterfaces
123:_make_descr_accessor( 'bNumInterfaces' );
lib/Device/USB.pm
918: hashStoreInt( hash, "bNumInterfaces", cfg->bNumInterfaces );
924: list_interfaces( cfg->interface, cfg->bNumInterfaces )
Please log a bug upstream [1] for this issue
All the best
