Hi,
 I reviewed the hciconfig.c.
 If you set mode 5, it just output like you test. I can see any limitation of the mode num, 5 it can be dealt with. So, I don't think it can give such a conclusion you claimed.
 
static void cmd_inq_mode(int ctl, int hdev, char *opt)
{
 int dd;
 dd = hci_open_dev(hdev);
 if (dd < 0) {
  fprintf(stderr, "Can't open device hci%d: %s (%d)\n",
      hdev, strerror(errno), errno);
  exit(1);
 }
 if (opt) {
  uint8_t mode = atoi(opt);
  if (hci_write_inquiry_mode(dd, mode, 2000) < 0) {
   fprintf(stderr, "Can't set inquiry mode on hci%d: %s (%d)\n",
      hdev, strerror(errno), errno);
   exit(1);
  }
 } else {
  uint8_t mode;
  if (hci_read_inquiry_mode(dd, &mode, 1000) < 0) {
   fprintf(stderr, "Can't read inquiry mode on hci%d: %s (%d)\n",
      hdev, strerror(errno), errno);
   exit(1);
  }
  print_dev_hdr(&di);
  printf("\tInquiry mode: ");
  switch (mode) {
  case 0:
   printf("Standard Inquiry\n");
   break;
  case 1:

it means that they support the inquiry mode command, but don't do
actually anything with it. Setting it to 5 is not allowed. So this
command should fail and later on it should retrieve only 0 or 1 as valid
values, but it doesn't. This leads to the conclusion that they only
store the inquiry mode value somewhere, but never evaluate it. And this
means they will never switch to Inquiry with RSSI as you have seen
before.
