Hi Oliver,

      3.10.2 booted on Pandaboard. Now, I am trying to connect Prof 7500 DVB-S2 
device. It does not get detected as new USB device.

     .config file is attached to this email. Am I missing any config? Can you 
please let me know?
From a quick glance I noticed you are missing the CONFIG_USB_EHCI_HCD (EHCI Host controller) it appears you don't have a USB host controller enabled at all? But i'm not sure what kind of USB controller omap4 has.

While I understand you prefer to run a LTS distro, 3.2.0 is old!

The reason why I keep bringing this up, media drivers are almost updated
daily. So if you want to see if your issue is fixed, the most ideal
start for this investigation is the media git kernel tree. While I
understand building your own kernel might be a little too much, try an
Ubuntu 13.04 Live cd, it should come with a 3.9 kernel, not extremly
old, but should have most of the recent media changes. Now if it doesn't
work right on that, well, then you'd have to build your own media
drivers from the git tree. If those don't work, then we can start
talking to developers. Otherwise, you are trying to troubleshoot
something, that has long been fixed.

Dear Oliver,

          Thanks for your response. I tried with 3.10.1. As you rightly pointed out, it 
does not seem to work on my board (pandaboard). It gets stuck at "Starting 
kernel...".

           Now, I am trying with 3.4.47 version now. Let me see if it works. 
The delay of creating /dev/dvb/adapter0/frontend0 and /dev/dvb/adapter0/demux0 
seems to exists. I am waiting for it to get created.

         I am downloading 3.4.54 and 3.10.2 now.
What do you get when using on a regular PC? Your beagle board may (or may not) 
yet be supported by mainline 3.10.1 kernel.

Try it in a regular PC and see what happens there with 3.10.2

Regards,
Kishore.

Dear Oliver,

       Thanks for your response. Here are more details. Please help me in 
making this work.

       Linux version:

-sh-4.1# uname -a
Linux (none) 3.4.0 #28 SMP PREEMPT Tue Jul 23 16:24:14 IST 2013
armv7l GNU/Linux
Your kernel is ancient. The latest kernel with the latest media fluff is 
3.10.2; Since you are on arm, chances are your platform isn't that well 
supported with later kernels, but even in the 3.4 world your kernel is ancient. 
Latest stable is 3.4.54.

So you are asking for help, with something that could have been fixed 3 times 
over (or not, I don't know). So my first suggestion is to upgrade your kernel. 
If that's not possible on your arm platform, contact the supplier of your 
kernel.

Meanwhile, since this is an USB device, you could try it on a desktop.
Get a recent Ubuntu live CD and see if it works there. At least then you can 
quickly and easily see if your problem hasn't been fixed in the last year.

Hi,

          I am trying to use Prof DVB-S2 USB device with Linux host. Device 
gets detected. But, I am facing the following problems.
You will need to provide much more information then that. What does
dmesg say? lsusb? what driver are you using, what kernel version? Are
you using it as a module? Have you enabled debugging in your kernel?

Those questions come to my mind.


1.      It takes approximately 21 minutes to get /dev/dvb/adapter0/frontend0 
and /dev/dvb/adapter0/demux0 to get created. This happens every time
2.      After /dev/dvb/adapter0/frontend0 gets created, when I use w_scan 
utility to scan for channels, it does not list the channels.
a.      In dmesg logs, I see DEMOD LOCK FAIL error continuously.
Paste your logs (or if its too much, only copy/paste the relevant parts.
You ask for a limb, yet offer nothing.

oliver

           Can you please help me?


Regards,
Kishore.
