Emeric，

From your usbmon trace, I can find that your TX is extremely slow:

          It may take several seconds to complete one packet with 1514bytes.

Could you run upstream kernel(3.4 or 3.5-rcX) first to see if the hardware of
your smsc95xx NIC is OK? And you'd better to test a usb storage transfer
on the omap4 ehci host.

I guess the hardware of smsc95xx may be bad.

Thanks,
