I'm not sure if it is an hardware limitation since the sprue35.pdf document(TMS320DM644x DMSoC Universal Serial Bus (USB)Controller User's guide) says: The USB has the following features: ยท Supports 4 simultaneous RX and TX endpoints, more can be supported by dynamically switching. I tried with the 2.6.20-omap git kernel and I am able to configure my 2 usb ethernet but after that the networking drops dead. I'm not able to ping anything. The 3 interfaces(eth0 onboard eth, eth1 usb-eth1, eth2 usb-eth2) are not usable but ifconfig shows eth0 eth1 eth2 up and configured correctly.
