Hi,

I am trying to get this device to work on my laptop without any success so far. 
The device is not recognized at all. I Installed v4l-dvb-kernel too. I can 
start em28xx with modprobe without any problem. When I attach the device all I 
get is:

Mar 23 21:44:53 laptop kernel: [ 5838.969388] usb 1-2: new high speed USB 
device using ehci_hcd and address 4
Mar 23 21:44:53 laptop kernel: [ 5839.104846] usb 1-2: configuration #1 chosen 
from 1 choice

And when I start the module:

Mar 23 21:46:20 laptop kernel: [ 5926.118227] Linux video capture interface: 
v2.00
Mar 23 21:46:20 laptop kernel: [ 5926.160302] em28xx v4l2 driver version 0.0.1 
loaded
Mar 23 21:46:20 laptop kernel: [ 5926.160598] usbcore: registered new interface 
driver em28xx

That's all. Even if I remove reattach the device I get only the two usb related 
lines above, nothing else. I am sure I am missing something (other kernel 
mods?), but I am stuck now and need advise.

I posted the tech specs in the linuxtv.org's wiki 
(http://linuxtv.org/wiki/index.php/KWorld_ATSC_315U) with pictures. Also the 
lshub result is there.

Further information according to the em2880 wiki:

1. location, standards
Florida, USA (NTSC, ATSC, HD/Digital OTA, Analog/Digital cable, clear QAM)

2. dmesg messages are above

3. lsusb is posted in the linuxtv wiki, link above

4. lsmod
