USB Problems

Rensin · 14 Mar 2016 at 12:50

Hi,

Have a problem with very slow transfer speeds, when I built my current pc transfer speeds were about 80MB/s but now struggle to reach 10MB/s.
All drivers are up to date.
Have tried USB pen drives (Corsair Voyager USB 3.0 & DataTraveler G3 3.1) & external hard drives but the same.

I'm trying to transfer 300GB of files to the external drive.

Issue 2 is that some devices will only work in certain usb ports, for instance the Logitech unifying adaptor will only work on port 4, external hard drive (Seagate Expansion Drive) will only work on the 3.1 ports and the color monki calibrator will only work on 1 of the front USB ports.

Motherboard is MSI x99A Krait Edition and using Windows 10 Pro 64 bit.

Any help please?
thanks.

Sounds like an issue with the motherboard, only way to be sure would be to reinstall windows.

Uninsall all the Universal Serial Bus controllers via Device manager and restart.

Another thing you can try is booting from a linux boot CD and try copying files

ok just uninstalled all the USB controllers and now get 15MB/s on a USB3 pen drive.

Have just bought an Anker external USB3 hub powered externally and also same speeds.

Checking the MSI site for BIOS updates i notice there have been a few USB fixes is the BIOS up to date?

yeah running the latest BIOS mate.

Have just tried on my HTPC which is also running w10 and have the same problem. Both hard drive and pen drves.

I know the problem now points to the USB pen/hard drives but surely not all of them can be broken at the same time?

Have you installed the driver required?

Rensin · 14 Mar 2016 at 18:17

Have just ran USB Device Tree Viewer and it shows the drive is connected via USB 2.0.

TWiNKLeT0Es · 14 Mar 2016 at 18:48

When the USB 3 device is connected is it listed under the USB 3 controller when expanded in the Device Manager?

Are you using the ports at the rear of the board?

Rensin · 14 Mar 2016 at 20:00

Using the rear ports yes, the top 2 ports are USB 2.0 which have my mouse & keyboard connected to the rest are 3.0. (2 ports 3.1)

Not sure which controller the pen drive is connected to, it just shows mass storage drive.

What size files are we talking? I get write speeds of 50MB/s no problem using files that are several GB in size. But when I copy PortableGit, which is thousands of tiny files, speeds drop to less than 1MB/s. I also tried a folder full of mp3s (average 8MB) and write speeds were 20-30MB/s.

Setup: USB3 hub built into monitor connected via USB3 cable to rear port on mobo, 16GB Sandisk Ultra USB3 stick.

Rensin · 14 Mar 2016 at 20:50

Have tried several files mate mostly single files ranging from 2gb to 20gb

marc2003 · 14 Mar 2016 at 21:19

Well you should definitely be getting full speeds then. I even tested my USB3 stick in the front USB2 ports on my case (cheap - has no USB3) and get 40MB/s write. Perhaps this is because everything is Intel on my board. I notice you have VIA and Asmedia in addition to Intel. It might be worth trying to pinpoint the Intel ports and using those.

edit: I noticed the VIA controller has microsoft in brackets which means it's using the drivers built in to windows. Check the VIA website for updated drivers. Ignore the microsoft in brackets next to Intel - they don't provide updated drivers.

ok, just installed the VIA driver (not showing microsoft anymore) but still the same.

The Pen drive is now showing as "Device Bus Speed: 0x03 (Superspeed)" in USB Device Treeviewer so is now been read as a USB 3 drive.

Will try to find the Intel ports although the manual isn't much help.

Rensin · 14 Mar 2016 at 22:06

have found the Intel ports (2 below the 3.1 ports) and same speeds.

Also tried my external hard drive (mains powered) and got a constant 140MB/s.

Might grab my spare SSD at the weekend and install w7 to see if there is any difference.

Have you tried a different psu?

Had usb problems once on a customers pc and turned out to be the psu causing it

Have my old psu laying around I could try. My current psu is only about 3 month old and not having any problems elsewhere.

Have ordered a few different pen drives to try too

Borrowed a mates 32GB Sandisk pen drive which instantly went to 50+MB/s for a few seconds but dropped back to sub 20. This was on a 1.5GB mp4 file, while a 800mb file will copy at a constant 50MB/s. It seems anything above 1GB will copy slowly.

Check what the removal policy is set to?

Right click on the drive letter in file explorer > Properties > Hardware > Select the drive and click properties > Policies > select better performance.

If you have the option write-cachcing make sure it is ticked.
