The communication between your device and the CPU on the libertas
device seems to be correct, otherwise you'd have error messages
in your dmesg.
You can also turn run "lbsdebug +enter +host +cmd +hex" to get
even more info, but apparently the libertas device doesn't give
you any scan results back.
Please consider a broken antenna, antenna socket or otherwise
some error in your RF setup. Or maybe you have 802.11a
access-points on 5 GHz, while you card can only run 2.4 GHz.
Here's for example a dmesg output of a successful scan:
libertas cmd: DNLD_CMD: command 0x0010, seq 239, size 18
libertas cmd: CMD_RESP: response 0x8010, seq 239, size 18
libertas cmd: DNLD_CMD: command 0x0028, seq 240, size 12
libertas cmd: CMD_RESP: response 0x8028, seq 240, size 12
libertas cmd: DNLD_CMD: command 0x0006, seq 241, size 67
libertas cmd: CMD_RESP: response 0x8006, seq 241, size 109
libertas cmd: DNLD_CMD: command 0x0006, seq 242, size 67
libertas cmd: CMD_RESP: response 0x8006, seq 242, size 11
libertas cmd: DNLD_CMD: command 0x0006, seq 243, size 67
libertas cmd: CMD_RESP: response 0x8006, seq 243, size 351
libertas cmd: DNLD_CMD: command 0x0006, seq 244, size 53
libertas cmd: CMD_RESP: response 0x8006, seq 244, size 11
See how big the size-numbers for the scan-responses are. That's
because my device find some APs and returns all the data back.
In your case, with 11-bytes-only response, it doesn't find
anything. For example, when I deliberately scan only one
channel, where no AP is available, I'll get back the same 11
bytes as you. In the following example, I also turned
on "lbsdebug +hex". Then I get back:
libertas cmd: CMD_RESP: response 0x8006, seq 246, size 11
libertas CMD_RESP: 06 80 0b 00 f6 00 00 00 00 00 00
And that is:
06 08 CMD_802_11_SCAN (actually a response, because the
high bit is set)
0b 00 size of response (== 11 bytes)
f6 00 sequence number
00 00 result of command exection (== success)
00 00 buffer size of scan response
00 00 number of APs in response set
