It is hard for me to read the differences between guspnp7 and guspnp9 given that guspnp9 was run thru indent. Typically , this should be done after all the changes have gone in and the driver was tested. So in the meantime, can you drop in the sb* from guspnp7 into guspnp9 and see if you still have problems with recording? You will have to hack the guspnp7 sb* code a little to get it to compile with guspnp9. I moved back guspnp7 to my ftp site in case that you need it. The speed or frequency problem is most likely related to the sb module not setting properly the frequency .
