`jr3_pci_alloc_spriv()` initializes `spriv->range[8]` to use a maximum value of 65536, but that will be overwritten with 65535 at a later time by `jr3_pci_poll_subdevice()` once the "set full scales" command is complete. The initial setting looks like a mistake. This range is only associated with a couple of dummy channels (channels 56 and 57) to read back the model number and serial number, so no user code should be attempting to convert those numbers to physical units. Just change the initial value to 65535 to match the final value.
