I'm not a superuser, only a hobbyist. I really just want this to work ~.~ so I can get on with my life. Sigh. Anyway, grumbling aside, I hope people can help.

1 Answer 1

This applies to 14.04:

The easiest way around this, I found, was to downgrade the kernel to the precise kernel: Go to http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-precise/ and download the packages

linux-headers-3.2.0-030200-generic_3.2.0-030200.201201042035_amd64.deb
linux-headers-3.2.0-030200_3.2.0-030200.201201042035_all.deb
linux-image-3.2.0-030200-generic_3.2.0-030200.201201042035_amd64.deb

You can do that with wget:

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-precise/linux-headers-3.2.0-030200-generic_3.2.0-030200.201201042035_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-precise/linux-headers-3.2.0-030200_3.2.0-030200.201201042035_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-precise/linux-image-3.2.0-030200-generic_3.2.0-030200.201201042035_amd64.deb

Then install them:

sudo dpkg -i linux-headers-3.2.0-030200_3.2.0-030200.201201042035_all.deb
sudo dpkg -i linux-headers-3.2.0-030200-generic_3.2.0-030200.201201042035_amd64.deb
sudo dpkg -i linux-image-3.2.0-030200-generic_3.2.0-030200.201201042035_amd64.deb

Then you need to reboot into the 3.4 kernel. You do that by selecting Advanced and then selecting the 3.4 kernel in the boot menu of Grub. If it works you need to configure Grub to use that kernel.

I'm just doing this myself, so I may post a follow-up of how to...

Try Set "older" kernel as default grub entry

EDIT: Try the kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-quantal/ It worked better for me, because I had a problem with sound with my headset with the earlier version.

@guntbert, why did you edit it to an even older version? 3.4 works, in fact probably better than 3.2. One doesn't even need to install another driver then.

Would I still have the option to switch between kernel 3.2 and my current kernel, or does doing this somehow remove the ability to boot with the original kernel? I have the same compilation issue. This adaptor is very slow, and I'm told if you install these drivers it will work faster. –  Andi Jay Nov 1 at 18:53
