[etherlab-users] EtherCAT master stuck waiting for devices

I am using EtherCAT: Master driver 1.5.1 with Linux kernel
I built with ./configure --enable-r8169 and all went well but when I 
start the driver with:
"/etc/init.d/ethercat start" I see the following with dmesg:

EtherCAT: Master driver 1.5.1 0f7a243b03e4
EtherCAT: 1 master waiting for devices.
r8169 0000:03:0f.0: PCI INT A disabled
ec_r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded
ec_r8169 0000:03:0f.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19
ec_r8169 0000:03:0f.0: (unregistered net_device): no PCI Express capability

XID 04000000 IRQ 19

The message "EtherCAT: Accepting device ..." never appears.

Anyone know why the master doesn't accept the device?
Any suggestions for troubleshooting?
