Hi Guys,
When I boot up my computer and try to connect to an USRP2 node, then
the first connection never works, but subsequent ones are working
perfectly.
1) uhd_find_devices always works:
linux; GNU C++ version 4.6.3; Boost_104800; UHD_003.005.004-5-g6bb62ea3
--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:
type: usrp2
addr: 192.168.10.2
name:
serial: 322
2) but uhd_usrp_probe does not work at the first try:
linux; GNU C++ version 4.6.3; Boost_104800; UHD_003.005.004-5-g6bb62ea3
-- Opening a USRP2/N-Series device...
-- Current recv frame size: 1472 bytes
-- Current send frame size: 1116 bytes
UHD Error:
Control packet attempt 0, sequence number 1:
RuntimeError: no control response, possible packet loss
UHD Error:
Control packet attempt 1, sequence number 2:
RuntimeError: no control response, possible packet loss
UHD Error:
Control packet attempt 2, sequence number 3:
RuntimeError: no control response, possible packet loss
Error: RuntimeError: link dead: timeout waiting for control packet ACK
3) my system is
Linux node1-2.sb2.orbit-lab.org 3.5.0-43-generic #66~precise1-Ubuntu
SMP Thu Oct 24 14:52:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
4) pinging the usrp2 node does not help, no matter what I do, I can
never access the usrp2 right away, only on the second and subsequent
try.
Any idea what could cause this?
Miklos

Hi all,
I'm a user of USRP B210. Now I tried to install UHD on Ubuntu 12.10 x86_64.
After installing the latest UHD, I run uhd_usrp_probe command and got error.
Then I tried to change different usb port on my PC, including usb 2.0 and usb
3.0 ports. However, each time I just got the same error. Is there anybody can
help me to solve this issue. Thanks in advance.

Dear all,
Recently I've been working on sampling at sample rate 50M. To avoid the
overrun error I set the parameter, over the wire, to 8bits. I simply
connect the UHD source with a fft scope in gnuradio companion and try
sample the environment noise as a test. But as far as I saw, the shape of
the signal sampled by 8bits was quite different from that sampled by
16bits. The power level is different, the trend of the shape also
different. Has anyone here ever used 8bits sample over the wire before? Is
the data trustful? I know maybe this is a problem of scale, from 16 to 8,
but I think only people use 8 bits sample when they need high bandwidth
which means they care a lot about the data "accuracy".
Any help, Thanks.
Bests,
yilin

That's most likely some sort of odd network problem. I'll see that if I
have USRPs connected through a switch (or multiple switches) and the switch
isn't setup properly, or possibly if the network link is overloaded.
I'd be curious to see the replies from the Ettus folks of when they
typically have seen this error.
Trying specifying the address like this: "uhd_usrp_probe --args
addr=192.168.10.2" and see if it gives the same thing.

It has to be software problem on the host side, since everything works
fine with 32-bit ubuntu. Actually, this is the stock 64-bit and 32-bit
image on orbit-lab, and I cannot figure out the exact cause of it.

Yes, it does give the same error.

I do not know. How can I check how it is configured?

Ping works perfectly and does not help at all. Even after the ping the
first uhd_usrp_probe fails, the second works.
One more thing, if I quickly try to do an uhd_usrp_probe right after
the second, then that can also fail, but I do not have the error
message at hand. I will try to get that and post it here.
