[Bluez-users] hcidump output problem

Hi All,
I am using bluez-libs 3.14, bluez-utils 3.14, hcidump 1.40 ..
when I am using hcidump -V -X I am continuously getting following output..

SCO data: handle 92 flags 0x00 dlen 48

    0000: 00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  ................

    0020: 00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  ................
 It gives nothing else ...
