Anyway, "urb->transfer_buffer" was initialized with

eh? I would think dev_kfree_skb(), because who knows whether the skb was
cloned, split, data buffer adjusted, destructors need to be called...
Well, we don't actually have the skb available any more.
You do:
urb->transfer_buffer = skb->data;
urb->transfer_buffer_length = skb->len;
__fill_isoc_desc(urb, skb->len, le16_to_cpu(husb->isoc_out_ep->desc.wMaxPacketSize));
_urb->priv = skb;
so it looks like you can grab it out of the 'priv' field.
And a damned good thing too...
