Asus U36SD usb 3 disconnect problem

I have a problem with usb3 and my little WD Elements 1TB external drive that's powered from the usb port. Initially it disconnected at once I tried writing to it. After removing anything usb hub related through the device manager and removing and re-installing the fresco drivers, it works for about ten seconds before it disconnects. Using it under the usb 2.0 ports it works as it should.

Reading when using usb 3.0 seems to work, it have disconnected once when doing that too, but I can't reproduce it.

Any ideas or suggestions? Who to blame and ask for a fix - the place where I bought the Notebook or where I got the disk...?

 

USB 3.0 disconnect is a pretty common issue. It's not exactly certain what causes it, but it happens across a variety of notebooks, USB 3.0 chipsets, and external devices. The Fresco Logic drivers supplied by Asus are very much out of date. You can find more recent ones here. Start with the most recent version and work backward if you still experience problems.

 

Thanks for pointing me to those drivers, there were no drivers to be found at frisco's website and I thought Asus actually did have updated ones. Unfortunately none of these more recent drivers worked. With the latest 3.5.4.0 I was happy for about a minute or even more, until the same disconnect (and immediate reconnect, which I forgot to mention above) happened. Frustrating to say the least. I was under the impression usb standards were well thought out, tested and pretty much fool-safe, but apparently not.

This is starting to make me think of returning this computer actually, unfortunately I didn't buy the disk on the same place so I could have an easy way to try another brand/model of disk first.

 

Hi, did you manage to solve that problem, I have exactly the same problem with the same laptop and the same disk.
I can't find the solution...

Thank you,

Manuel

 

Darn... No, I didn't find any solution. "Darn", because my disk seems to be broken, it has crashed and lost the partition tables twice now, and I hoped the disconnection problem was because of a faulty disk. I'm going to return the disk next week. If you have the same problem it's most likely that it wasn't just my single disk, but something with that line of disks or the driver or controller incompatibility.

 

Frescologic 3.5.24.0 works perfectly fine on my u36sd usb 3.0 port.
No disconnection or time out whatsoever on my wd passport 1tb

 

Did you have disconnection problems with earlier driver versions?

 

I tried all the drives and I still have problems... I think is the disk I allready used other brand of disks and a card reader all with usb3, and with those things I didn't had problmes...

 

I meant to ask jackluo923...

jackluo923 - did you experience any disconnect problems with earlier drivers?

(It seems you can't PM people on this forum? )

 

Guys, just download the latest drivers from this link

FRESCO LOGIC

 

That's the very same page where I've downloaded all updated drivers from, and up to and including 3.5.24.0 none have worked.

Latest 3.5.30.0 is untested, as I couldn't find the cable to the disk yesterday... Will come back with a report later.


edit:

jackluo923 - please inform us if previous driver versions failed for you or not.

 

With latest driver fresco logic 3.5.30.0 the disk still disconnects after between a few seconds and nearly a minute.

It's only when writing files this is happening. I made a low level format after the latest partition table crash, and the process ran uninterrupted for something like two hours. I will continue trying linux and see what's happening, apparently usb3 is working without any tweaks in latest ubuntu.


edit: new page and a renewed request to jackluo923 - did you experience any problems with earlier drivers?

 

Sorry, had a busy week. The drives only work with 3.5.24. All other drive, both newer and older ones will disconnect after 10 seconds of transfering files larger than 10GB.

 

Ok, for me writing in general regardless of file size doesn't work with any driver I've used including 3.5.24.0. It disconnects within a minute when writing continuously/copying files to it.

Note that I (and manuelcbarbosa apparently) have the WD Elements portable 1TB drive, not the Passport.

 

OK, got it working at least... Slower than it should be, but faster than plain usb 2.0.

Here's how I did it: First install version 3.5.24.0 (I used drivers found at FRESCO LOGIC).

Install them. (If you have the later version 3.5.30.0 you must remove it via the control panel first.) Then run the setup program again. You now have the option to change the installation. If you select that, and scroll down to the bottom, to the 64 bit part, you can choose to disable that.

After disabling the 64 bit part of the drivers, I haven't experienced any disconnects, but transfer speed has been slower than the short periods of time it has worked in between disconnects earlier. But it's faster than usb 2.0. It's also slower compared to transfering files under linux - live usb Ubuntu daily build 12.04 32 bit was what I tried. I couldn't get any version of 64 bit Ubuntu to work at all, it just freezes up with a blank screen.

Maybe earlier versions of the driver work too when disabling 64 bit functionality, I haven't tried that.

 

I am running the WD My Passport Essential SE 1TB USB3 version on the Asus U36SD (i7) on Win7 64-bit and have the same problem.

I did quite a bit of research on this drive the the guys over on the Mac were having problems with this drive too.

I just upgraded to 3.5.30 and so far for the last 10mins seems stable using USB3 cable but speeds were similar to USB2.0 speeds on the same port.

 

hi
i have same problem with wd external hard drive and asus n43sn
i download usb3 driver from freso logic FRESCO LOGIC and my problem have solved
im happy now thank guys

 

I tried in triplicates to transfer 50 files (7.96Gb) with
1) Original Driver
2) Latest Driver with patch
3) Version 3.5.24.0 (said by one member)
in this order (you had to delete any install when you do 3).
For each try, the disconection occured:
1) 1, 1, 1.
2) 2, 1, 3.
3) 0, 0, 0.

I not tried other files..
I just registered to say that this version 3.5.24, maybe, is the best one for ASUS U36SD.
