Yea tbh i didn't expect this to fix it, since i think the mappings are fine, but
it never hurts to verify.
@Jose: Can we add some debugging prints on the driver?
Ideally the pages the api allocates (on init), the page that the driver is
trying to use before the crash and the size of the packet (right from the device
descriptor). Maybe this will tell us where the erroneous access is
Thanks
