Anyway, if your issue on the pandaboard is that it's not showing up in lsusb, you probably are missing USB drivers (i think we talked about that previously)
Those crashes you posted, I have no idea where or what they cause. If this is from booting without USB stick plugged in, deffinatly ask on some pandaboard list/forum. If it only happens when plugging in your device, then it might be related to the dvb driver, but even there I have my doubts.

I am using Kaffeine.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. oliver-----Original Message----- From: Oliver Schinagl [mailto:oliver+list@xxxxxxxxxxx] Sent: Wednesday, July 24, 2013 4:34 PM To: Krishna Kishore Cc: linux-media@xxxxxxxxxxxxxxx Subject: Re: Prof DVB-S2 USB device On 24-07-13 10:59, Krishna Kishore wrote:Dear Oliver, Thanks for your response.

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.[dotconfig is attached to this email] lsusb -t: /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-omap/3p, 480M |__ Port 1: Dev 2, If 0, Class=, Driver=hub/5p, 480M |__ Port 1: Dev 3, If 0, Class=, Driver=smsc95xx, 480M |__ Port 2: Dev 5, If 0, Class=, Driver=dw2102, 480M dmesg: [ 126.824951] usb 1-1.2: new high-speed USB device number 5 using ehci-omap [ 126.950347] usb 1-1.2: New USB device found, idVendor=3034, idProduct=7500 [ 126.957794] usb 1-1.2: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [ 126.983184] dvb-usb: found a 'Prof 7500 USB DVB-S2' in cold state, will try to load a firmware [ 127.033477] dvb-usb: downloading firmware from file 'dvb-usb-p7500.fw' [ 127.051177] dw2102: start downloading DW210X firmware [ 127.238739] dvb-usb: found a 'Prof 7500 USB DVB-S2' in warm state.
