I don't understand what the problem is.  Anyway, we could do the following:
restore these fields in the public part of struct usbatm_data:

        int tx_endpoint;
        int rx_endpoint;
        int tx_padding;
        int rx_padding;

The driver can set them in the bind method if it wants.  After bind, the
channels are setup.  I guess at this point the core works out what kind
of endpoint it is (bulk or iso).

Ciao,
