    If I understand both Davids correctly this is the solution.
    Buffers for dma must be allocated seperately using a special allocation
    function which is given the device so it can allocate correctly.
    David B wants a bus specific pointer to a function in the generic
    driver structure, right ?

    Eventually it could be exactly that, via the generic driver struct.

    For now it can be a usb specific thing, and when the generic device
    stuff is ready we just go:

    #define usb_pool_alloc(...) dev_pool_alloc(...)

    without having to touch any of the driver call sites.
