G751 - Problem with USB3.0 ports (left side) and external HD... anyone else?

[Richdog]

So, I am now experiencing a problem whereby when I attach my external 3.5" WD HDD to the USB ports on the left side of the ASUS G751 and copy large amounts of data, the throughput will drop and then the HDD will disconnect. I verified this multiple times in both ports. In the ports on the right side, it works fine.

I did some reading and found a forum post where someone stated: http://forum.notebookreview.com/asus-gaming-notebook-forum/765303-considering-g751.html#post9836352

next.... USB 3.0 problems..

basically, I had to connect my USB drives to the right ports and the left ones were kept for my mouse and printer? why? because ASUS cannot produce a piece of hardware that functions right! they claim all ports are USB 3.0 and they are all in blue color...BIG LIE! it wasn't only me, I posted this on the ROG forums and every single one of the members verified the same!

My question is what the hell is causing this, and how can it be fixed? I do not want a laptop where 2x USB ports are essentially useless, and this seems to be a widespread issue dating back to earlier models like the G750. Why has this not been addressed and fixed?

If anyone else has this issue please post here... :mad:

First, I want to say THANK YOU for bringing this up and for Gps3dx's detailed guide.

I've been struggling understanding WHY my external drive would just hang up mid transfer on 3.0, but work perfectly fine on 2.0, and this is the only thread I could find with an alternative/custom drivers approach, the general solution usually being to tweak the power management of USB.

I have the ROG GL552VW (BB71-CB to be precise) on Windows 10 x64 Familly edition, with vers.300 for the BIOS. It has two 3.0 and one 3.1 port on the left, none works with the external drive. The drive is the stock 1TB hdd that came with the laptop (ST1000LM 024 HN-M101MBB SCSI, by Seagate I believe), placed in a StarTech enclosure w/UASP (UNI251BMU33). Following you're guide, I went to the win-raid forum, and went to the Intel USB 3.0/3.1 Driver section, b) Latest modded Intel USB 3.0/3.1 drivers. The drivers were last updated on 27/01/2017 and they now have a Driverpacks for the automatic installation via DPInst option, which made things sooooo simple.

0) Create a restore point
1) Run the CMD file as Admin for the certificate
2) Run the DPInst.ex. as Admin
3) Reboot when finished
and voilà, everything works and the drivers looks like the ones in your screenshot.

The hard drive now has a steady 101 Mbytes/s Up and Down (tho turning off indexation for the drive gives me a wooping 2Gbytes/sec, for the first 2Gb lel) using mp4 files from 60MB to 1,2GB or 101/140 MB/s Up and Down with 2 000 Word files (1,3GB).

--------------------------------------------------------------------------------------------------------
Now, the AI Suite 3 tweak. I had to install it manually, so I didn't have the choice between BOOST mode and UASP mode (dunno how to set that manually). In the end, no change to the drive speed. I did see a change with my USB 3.0 thumb drive, only problem is I only tested after installing the modded driver AND updating the thumb drive with Asus Boost, so can't be sure if it actually does anything.

Sandisk Ultra Flair USB 3.0 32GB (SDCZ73)
Before: 70MB/s write to, 90MB/s read from. The drives heats up rapidly after 1 GB and write speeds drop to 20MB/s. Read speed is fine.
After: 101MB/s write, 140 MB/s read. The drives heats up rapidly after 1 GB and write speeds drop to 20MB/s. Read speed is fine.
(using mp4 files from 60MB to 1,2GB)

Glad to see that my guide help other G serie members as well... good to know.

About AI Suite 3, it is highly experimental, since it wasn't really suppose to work on Asus G serie and even its hole laptop series AFAIK.
when you install AI Suite 3 ( the UASP driver aka "USB 30.0 boost", and ONLY THIS, since other parts of the main installer can cause not very nice behavior, many force-close etc.. ) you get a GUI with it as well.
I know that 1st time you launch, it might not show the GUI up, although it runs in the background... just kill it using the task manager and run it again ( as admin always recommended ).
Then, connect your USB, let windows recognize it as it normaly does, then It should show up in the AI suite's USBboost GUI - and on the right, you can toggle between regular driver and its own UASP supported drivers ( see screenshot here ).

Lastly, as I wrote in the guide, tha usb 3.0 boost driver doesn't enhance ALL usb 3.0 devices... so it's really difficult to say who can benefits from it.

Hi,

I too must say a thank, because this workaround worked also for the left USB 3 ports of my G752VS !

The USB 3 external hard drive is now recognized and fonctional on the left USB's.

I used the "NEW: Driverpacks for the automatic installation via DPInst" under the Intel driver download link http://www.win-raid.com/t834f25-USB-Drivers-original-and-modded.html.

Thanks for the Guide my friend.. i didnt use the DPInst cause its causing hangups on me, but i manage to install it manually, now in my Device Manager look the same as Gps3dx's picture.. but my write speed on my flash drive and Passport is still 10-12MB/s (Kingston 3.0 16GB) and my WDPassport Ultra 1TB is 75-101MB/s(75mb ave) on all ports. same thing with"Intel® USB 3.0 eXtensible Host Controller Driver - (MICROSOFT)" version.

This works for me fine Thanks everyone 😄

Just a note. I have also installed the latest modded Intel USB 3.0/3.1 drivers (27/01/2017) via DPInst.
Haven't tested them yet with all my USB 3.0 drives/pens (transfers and stability) but at least I have not noticed any drawbacks so far.
I will report later.

The result for me is no change - still the left bottom USB port keeps disconnecting/reconnecting my Corsair Flash Voyager 16GB USB 3.0 pendrive at random moments... even during inactivity.
Other 3 ports are OK. Looks like it is hardware.

Hi, So I finally got to fixing the USB 3.0 Problem after avoiding ti for 2 years, But I'm facing now.
Thank you for posting this guide BTW. Its very informational.
Some Info:
G751JY-Win10x64.

Reason for doing it: I have a 1TB WD Elements(3.0). It works completely fine on my Assembled desktop, but only 2 port on my ROG is able to detect it. The right-side ones. Also it's more of hit and miss, sometimes I have to unplug and replug a few times before its detected. The ports on the left-side don't detect it at all.

So followed your guide and somehow it's worse now. The transfer speeds are down to 30MB/s (RAR file). And the hit and miss case has become worse.

I don't have any other external HDD's to test, but i remember once I connected a friend's Transcend HDD and had the same issue.

Thumbdrives/pendrives have no issues at all, they work fine on all ports. but the ones i have they are all 2.0 if I'm not wrong.

Any idea what's wrong with the ports and/or my WD elements?

Doesn’t work on G752VY as these machines inherantly have a vdroop issue on the Left USB ports. No driver or manipulation there or is going to raise the USB voltage. This has been verified**many times that the left ports which are actually on a board separate from the MOBO drop connection due to voltage drop.**

Ditto this has been a known issue since the G75VW

Latest modded Intel USB 3.0 drivers by Fernando from win-raid forum v5.0.4.43 are detected on all of my g752 and g751 as not digitally signed. Although Fernando claims their are signed. Yeah, I installed the certificate! I have the the older version 5.0.0.32 and they are detected to have Authenticode signing. Maybe there are some versions between the newest and 5.0.0.32 that will get detected as signed, but defenetly not 5.0.4.43. When I asked Fernando to fix his 5.0.4.43 signing or provide older versions, he told me for him v5.0.4.43 work and he does not intend to help he with my little problem.
Rather strange that the 5.0.4.43 are not detected as signed on my 5 asus laptops and no one has this problem, judging from win-raid forum.
