Hi Ash,

I have tested usbnet running on the 2.6.31 kernel. No packet loss like on 2.6.21.

You might want to bitbake -c menuconfig virtual/kernel and change:
Device Drivers -> USB Support -> USB Gadget Support -> USB Peripheral Controller from: Renesas M66592 to: PXA 27x

On gumstix run modprobe g_ether
pxaregs UP2OCR_DPPUE 1

And USBNet comes alive


Cheers
