Module verification failed

[Munted101]

Hi guys

I'm having real trouble getting this card to work, I've followed all the tutorials but I always end up back in the same place.

When attempting to taint the kernel, I get 'module verification failed'.

Short of re-compiling a modified kernel to sign ALL modules regardless, what else can I do?

Hi Munted101

Can you tell us that which operation you are using ?if for x64
please have a try
rm -rf /lib/modules/xxx/kernel/driver/media (xxx is your kernel version)
Then reinstall our driver again.

Thanks

Kind Regards

Yes, tried that unfortunately, still always the same result.

I have tried a different version of distro, using ubuntu myth rather that ubuntu server, but still the same.

Have also install in a different make of PC (under linux), and still the same.

However, card does work under Windows, but thats not ideal, as I specifically purchased this to work under linux.

Hi Munted101

Is your windows and linux are in the same PC?
and when you install driver in linux ,first have a check whether you PC detect TBS6285 card you can using
lspci -vv
whether have our device.

And you can send your dmesg log information to our support or my email steven#tbsdtv.com we will have a check with this.

Thanks

Kind Regards

Hi

please use our latest linux driver:
http://www.tbsdtv.com/download/document ... 150728.zip
which already fixed this issue.

Thanks
