iso support

I don't remember what that interface was...  In the case of the speedtouch,
you can only know whether you want iso or not by querying the device.  I
didn't like the idea of doing that in probe(), I'd rather do it in bind().
That leaves three possibilities: pass the info by modifying the
struct usbatm_driver (bad idea), by modifying something in the
struct usbatm_data (yuck), or by adding an extra parameter.  This extra
parameter is now a general "flags" parameter.  It's not a wonderful
solution, but it seems to do the job.

Once your driver is in the kernel tree, you won't be affected by this kind of
thing anymore.  Hopefully this change and your driver will go into the tree
together.

Not sure what you mean.
