Hello all,

I am trying to make LAN9730 working thru HSIC interface.  
I have made my own board. Both lines have same length of 55mm.

I installed the toolchain and compiled the driver.  
I load the driver on the WP7607:  
insmod smscusbnet.ko  
insmod smsc9500.ko

The modules are successfully loaded.  
But I see no Ethernet interface appearing.

With dmesg I see:

[2191.965712] usb usb1-port1: unable to enumerate USB device  
[2192.090192] usb 1-1: new high-speed USB device number 70 using msm\_hsic\_host

[2195.661057] usb 1-1: new high-speed USB device number 76 using msm\_hsic\_host

Any idea to make it works?  
Did I miss something?

Thank you for your support,

CS
