The code in `hdsp_get_iobox_version' (sound/pci/rme9652/hdsp.c) seems
to fail with the ExpressCard (perhaps it is related to HDSP_SHORT_WAIT).
If you have/use only the Multiface, you could try to replace this
function with
static int hdsp_get_iobox_version (struct hdsp *hdsp)
{
hdsp->io_type = Multiface;
snd_printk("Hammerfall-DSP: Multiface found\n");
return 0;
}
and recompile the module.
