HI, I am trying to enable usbProxy for Marvell PCB, and getting the following error while running usb-mitm

I had loaded both musb driver and gadgetFs

# lsmod 
Module                  Size  Used by
musb_hdrc              73027  0
gadgetfs               18305  1

I also tried the patch given in doc directory. Thanks in advance...

I'll give it a try: did you also disable the other conflicting kernel modules? see #62

[jishnuvijay1991]

Yes, I havn't loaded modules g_multi and libcomposite.

@jishnuvijay1991 Could you mount gadgetfs somewhere and see what the file(s) it has available? It sounds like it's not supported by our current list.

[jishnuvijay1991]

It contains a sigle empty file "mvebu-u3d"

[dominicgs]

That's not one of our supported platforms, but you could try adding it here: https://github.com/dominicgs/USBProxy/blob/master/src/Plugins/Hosts/GadgetFS_helpers.c#L188

[jishnuvijay1991]

We had added the it in the array already..

[dominicgs]

The code right beneath that is what produces the error message. It's not finding a match between a device file in the list and the device file present on the mounted gadgetfs filesystem.

[jishnuvijay1991]

You are right, Issue is resolved.
