assuming you mean the 800e (800i is the pci card I believe).  Here
is my
howto.  It is key to have a clean v4l then install em28xx-new then
reboot with the stick NOT inserted

I'd be happy to help further if this doesn't work for you.
Good luck,
James

Subject: [Em28xx] Pinnacle 800i HD PRO on MYTHBUNTU 8.04



Has anyone had any luck ... installing the EM28xx driver on
Mythbuntu ?
I have been through 3 versions of UBUNTU and I have exactly 1 HD
recording to
show for it. It worked once on Ubuntu 7.1 until a reboot ! The one
time
it worked the
picture from AN ATSC OTA station was great ! Enough to convince me
to
keep
trying with this USB Tuner.

It worked under Windows XP so the hardware is fine !

Any HOWTOS for MYTHBUNTU 8.04

Thanks

Steve

Hmm, not to hijack, but I tried installing the debs and they don't
work
for me.  Essentially the drivers install and load but don't do
anything.
It may be because I'm using kernel 2.6.24-7 instead of 2.6.24-16. For
some reason kernel.org doesn't have the sources for 2.6.24-16
available.
The output of dmesg is simply

[  339.322672] em28xx v4l2 driver version 0.0.1 loaded
[  339.322699] usbcore: registered new interface driver em28xx

Nothing beyond that about finding my devices or anything.

lsmod gives:

em28xx                 48680  0
compat_ioctl32          2304  1 em28xx
ir_common              36356  1 em28xx
videodev               29056  1 em28xx
v4l2_common            18560  2 em28xx,videodev
v4l1_compat            15364  2 em28xx,videodev
tveeprom               16784  1 em28xx
i2c_core               25088  5
em28xx,tveeprom,i2c_ali1535,i2c_ali15x3,i2c_ali1563
usbcore               146412  5 em28xx,usbhid,ehci_hcd,ohci_hcd

And trying to modprobe em28xx-dvb returns fatal, module not found.

So instead, I compiled the em28xx-new driver from source. They
compiled
fine with no errors, but then simply wouldn't load:

insmod: error inserting 'em28xx.ko': -1 Unknown symbol in module

Not sure what to try next. I'm going to try different kernels and see
if
I can compile one these will work with.


Cheers,
Raphy

I don't think you have the right modules loaded. my lsmod shows many
more.

Did you check which em28xx you're loading via modinfo.  Mine shows the
new one is loaded it is in the empia directory

[EMAIL PROTECTED]:~$ modinfo em28xx
filename:       /lib/modules/2.6.24-16-generic/empia/em28xx.ko


Make sure you aren;t loading the original v4l modules.  That is what
your dmesg indicates to me.  You should not have

/lib/modules/2.6.24-16-generic/kernel/drivers/media/video/em28xx/em28xx.ko

but

/lib/modules/2.6.24-16-generic/empia/em28xx.ko


I am not sure why you are using 2.6.24-7 as your kernel too,

Hope this helps. There was some alsa issue that causes compilation issues under ubuntu
hardy.

James



Yeah, I was using 2.6.24-7 because I custom compiled it. I've also used 2.6.25 on the same system. They were the basic kernels from kernel.org. Trying to compile the em28xx-new from source always resulted in "unknown symbol" errors. So I tried the .debs

At any rate, I tried with a vanilla install of 8.04 and the .deb files work fine then, with the default kernel of 2.6.24-16. I'm able to reboot the system with both devices plugged in and they seem to work fine (dvb - haven't tested analog yet), no hang and no need to keep one unplugged until boot finishes.

One problem with the new 2.6.24-18 kernel in Hardy for me is that I get em28xx-audio not loading properly when using the .debs. But sticking with 2.6.24-16 everything is fine.
Thanks
Raphy
