Hello to everyone, Basically, my problem addresses this site: http://www.linux-usb.org/usbtest/ Network Tests (Linux 2.6 and MS-Windows USB Hosts) __________________________________________ When Gadget Zero is basically working, you should start using Ethernet style testing also, the g_ether gadget driver. That normally uses CDC Ethernet to talk to hosts, and will cover important code paths that won't be addressed using "usbtest". Specifically, transfers go in both directions concurrently; they use queue depths greater than one; and the rates at which requests enter and leave the queues vary considerably more. (Races will show up a lot more readily!) I am pinging from the host target, and I see ARP requests Coming to target (properly dequeued from ep1out (all 42 bytes correct), but I do not see any messages coming to RNDIS, especially to f-n skb_pull(skb, ...). I have both loaded cdc_ether and cdc_subset drivers, And I assume that this is wrong! So, what should I disable in menuconfig in USB gadget framework so I do not see anymore cdc_subset driver? Once again, I apologize for my ignorance in USB area.

I am sorry, bu I do not really understand your question or how it is related to the host side driver I'm playing with. I do not have any access to the target side.
