[ SOLVED ] Slow USB 3.0 Speeds

[T1125P]

OK I can confirm 100% that the issue with USB 3.0 speeds is with Ubuntu  16.04 which LL 3.6 is based on. After installing Win 10 in order to update my BIOS I copied and pasted a 80GB file. Speeds were locked at 140+mb/s. Then I downloaded Ubuntu 17.10 64bit. Tested it out the same way copied a 80GB file and the speeds are locked as well at 140+mb/s. Also like to add this is with the exFat file system on Win 10 & Ubuntu.  Hmm, I wonder is there anyway to fix this ?

I would bet it has to do with kernel drivers for a newer kernel. If possible try the 4.10 kernel series (hwe ones).

OK thanks a lot I will look into that.

I have fixed the slow USB 3.0 issue by actually installing 4.13 Kernel. This is what worked for me hopefully it will help others:

To get the Kernel 4.13 from the command console, run the commands below one by one:

For 64-bit OS:

cd /tmp/

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13/linux-headers-4.13.0-041300_4.13.0-041300.201709031731_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13/linux-headers-4.13.0-041300-generic_4.13.0-041300.201709031731_amd64.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13/linux-image-4.13.0-041300-generic_4.13.0-041300.201709031731_amd64.deb

sudo dpkg -i *.deb

for 32-bit OS:


cd /tmp/

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13/linux-headers-4.13.0-041300_4.13.0-041300.201709031731_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13/linux-headers-4.13.0-041300-generic_4.13.0-041300.201709031731_i386.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13/linux-image-4.13.0-041300-generic_4.13.0-041300.201709031731_i386.deb

sudo dpkg -i *.deb
After installed these .debs, restart and enjoy!

Glad the kernel updated fixed this issue. It should be noted that the kernels are also in Install/Remove packages from the menu. Did you happen to try the 4.10 series and see if that fixed things or just went up to the 4.13 for good measure.

Lite Tweaks hosts all our kernels up to and including 4.14 under Kernel Installer.

supergamer I just jumped to 4.13 and installed it. I figured the higher the Kernel the more features it has
Thanks Jerry I did not even think to look there. Not a Linux expert yet haha, but trying to learn as much as I can and loving it.

Gratz!

Nice that the problem was solved... but strange that a 5 year old USB3 controller had to wait until now for kernel support.
Maybe it's a patent issue or something. Was beginning to feel sorry for (indirectly) suggesting the 6330, phew!

Cheers!

Hmm, actually I read that USB 3.0 support was supported in Linux from 2009 on. It could have been an issue with my USB 3.0 controller and the older Kernels. At least it's good now, and the E6330 is so fast with LL, everything just opens in  a snap.
