Usb otg 3.0?

I tested the Note 3 for USB 3.0 OTG connectivity.
I could not get Superspeed transfers, only USB 2.0 speeds.
I confirmed with the Charger Doctor and multiple USB devices on an unpowered hub that the Note 3 does output the full 900mA of current that a normal USB 3.0 port would. This means that the Note 3 is fully capable of outputting 900mA of current for OTG devices.
I confirmed that the Western Digital USB 3.0 My Passport hard drive (formatted to exFAT) was fully powered and provided sequential reads and writes.
However, the most I could get was 39MiB/sec, which indicates that it is operating at USB 2.0 speeds. Has anybody had success getting the Note 3 to operate at USB 3.0 speeds when using USB OTG?

Hi All
I am currently facing an issue with using a USB 3.0 Flash Drive on my N9005.
I recently bought a Kingston DTHX30/64GB from Amazon and the benchmark which I did personally at a IT Retail Shop at the mall using their AlienWare Laptop show that the USB Flash Drive is working perfectly at > 300/150 (W/R).
I bought an OTG Cable from a local online shop but the benchmark shows only 30/20 (W/R).
The only tests that I have yet to conduct is to borrow another N9005 to verify if the fault lies on the cable or my phone.
Anyone out there is facing the same issue?
Is this a firmware issue?

Pretty sure the standard OTG cables are usb 2.0 only. Need a OTG cable with the correct USB 3.0 connection.

The current USB 3.0 OTG comes from a Local Online Retailer in Singapore which got their cables from China too, but not sure if their source is reliable.
Anyways, I have ordered an OTG this time round that will be flying in to me from China. Let's see if this cable works.

Sorry for double posting as this is an update post.
The USB 3.0 OTG I personally ordered from China came today and I immediately put it to test.
The packaging and the cable is exactly the same as the one I bought from Singapore.
And the results? It's also exactly the same.
This time round, I am going down to Sim Lim Tower to get an Engineer to specially make one USB 3.0 OTG for me and I shall put that to a test. I think this will cost me like 15 to 20 USD (20 to 25 SGD)
I shall name my cables, OTG A (The one I initially bought online from Singapore), OTG B (The one I ordered from China) and OTG C (The one I get from Sim Lim Tower).
I have tested OTG "A" and OTG "B" using on my friend's N9005 and the results are the same.
The next test will be that, I will format my USB 3.0 Hard Drive to Fat32/exFAT and test using all 3 OTG cables.
Can it be my Kingston USB 3.0 Flash drive not compatible with the OTG Cable?
Please enlighten me. I saw somewhere on this forum that we need to activate USB3 on N9005 to use it?

I've been unable to get the SM-N900T to link up USB 3. I've been looking in the kernel source and doing some debugging and the USB 3 host controller isn't even registering a USB 3 device connected to the port. Just a USB 2 device. I've looked at some of the datasheets for the Snapdragon 800 processor in this phone and its not really clear if it supports USB 3 OTG, or just USB 3 MTP as a device.
I'd love to get a definative answer from samsung or qualcomm but for now i've given up on USB 3.0 OTG with the Note 3.

I too would love to hear if it is possible to get the phone to USB3 in OTG mode and not just MTP. I purchased 2 "USB3.0 OTG" cables expecting faster transfer speeds with my external USB 3.0 SSD or USB 3.0 memory sticks. No such luck.
When contacting the seller to inquire about the inability to transfer at superspeed, I was just given responses like it must be a bad cable and will issue a refund. I purchased 2 of these and both have identical transfers speeds.
Likely just get a refund as it looks like it may not be possible to switch the phone to USB3 for the OTG. Bummer.

I have a couple different cables coming today. If they both test at only USB 2 then I'm going to call it a fail.
What i really don't get is why the would put an xhci host in the snapdragon if they weren't going to support USB 3 in host mode.

I just posted some more results on USB 3 OTG support. I probably should have just put it in this thread but here is a link.
Short version. Still no luck

I've tried a variety of USB 3 OTG adapters and none of them have worked correctly. Suspect OTG functionality doesn't work with USB 3?

Okay
I have tested with 2 different 9005 and 3 USB3.0 OTG Cable from 3 different source.
Everything doesn't work. All possible test are conducted and test results are at USB2.0 speed.

N900 N9000 and N9005
N900 is the Note 3 Neo version. It has USB 2.0 only
N9000 is the Exynos version with USB 3.0
N9005 is the Snapdragon version wiht USB 3 ports but USB 2 speeds.
I want to buy this phone as I can use an Image App to control a camera, and then copy the SDXC card to a USB3 HDD.
Could someone kindly confirm with a quality USB 3.0 OTG cable that the N9000 Exynos version is capable of USB 3
speeds while operating as a USB 3 host ?

N900a n900t
I have both a N900A and N900T rooted and running android 5.0.1 roms.
Having the same results as the rest of you, ~35Mb/s transfer speeds on usb 3.0 otg with a ssd. Quite disappointing.

What's with the charging cable?

Anybody figure out why the both charging port and charging cable that the phone comes with, have what looks like a double plug? One is a common micro USB port, and it seems that I can charge the phone with any old Android charger, as it will fit in this port. The other kind of looks like a USB port that you'd see on a digital camera. Just wondering what this is for, and why the provided cable has both.
Thanks in advance!

It's a USB 3.0 port and cable. It allows for faster data transfer speeds when connected to a USB 3.0 port on a computer.
It's backwards compatible with USB 2.0, which is why you can also use the other cables with the phone.

You are half correct.... The right side is the micro usb port the left side is MHL 2.0, another version of HDMI out. You need a $13 adapter for this to work. Why Samsung put both on the same cable beats me.

Not true.
MHL works through the standard microUSB portion of the plug, just like it does on many other devices. The additional thinner side is to accommodate the changes for USB 3.0. The Note 3 was the first phone to use a USB 3.0 cable and have a USB 3.0 Micro-B port on the device, and Samsung is following suit with the S5. Samsung has been supporting MHL 2.0 since the S4, which only had a standard microUSB port, so there was no need to switch to a new port design just for that. And if you look at the MHL adapter you mentioned, it has a standard microUSB plug. The HTC One, HTC One Max, and HTC One (M8) (among other devices) also have MHL 2.0, and do so through a standard microUSB port. The extended port on the S5 (and Note 3) is for USB 3.0. It's not there for MHL.
And the Engadget review that you linked doesn't support your post, rather it just notes that the port supports MHL (which it supports it through the standard microUSB portion of the port).

Interesting. I got my $12 adapter in today and sure nuff, it is usb port only. Thanks, now I find this out I think that is stupid of Samsung to put the USB 3.0 extension as another port. Not that I use it that often....

There was no other way for them to add USB 3.0 functionality to the device while allowing backwards compatibility with microUSB 2.0. They wanted everyone to have the option of still being able to use their old microUSB 2.0 cables along with a different USB 3.0. I think it was definitely the right move instead of introducing a completely new plug that's not backwards compatible.
That said, a new USB 3.0 plug is coming that's not backwards compatible with USB 2.0 microUSB cables. It's been recently approved, but I'm not sure when we'll start seeing it on the devices.

Check out the USB plug. See the blue plastic insert? Denotes SS super drives. Huge transfer speeds

Whats the Usb for?

I have not seen or heard what the micro usb will be used for on the NP....

The ADT-1 has a USB port and all it can be used for is a keyboard/mouse currently. I'd kill for OTG support. That said though, the ADT-1 also comes with a splitter for the power that adds an additional USB port to connect to your computer to access it via the SDK. So, it could be very much the same setup, or something completely different.

Interesting... You would think they would list the use for it.. maybe these OTG cables i have will come in handy..

It's been said that usb to ethernet adapters will work.

You can connect an OTG cable to it. I connected a USB 3.0 HUB + Ethernet adapter to the OTG cable and connected my keyboard & mouse to the hub and a 64 GB micro SD card for extra storage. I also used the the ethernet port so now I don't need to connect through WiFi

Does xperia x compact support OTG ?

I change my phone to xperia x compact recently, I find the type-c USB is easy to use.
I have a otg usb drive with micro usb, which is working on samsung s7, dell tablet. I wonder if it can be used on XC.
Thanks

Not sure about your micro USB OTG drive, but I purchased a separate OTG type-C adapter which connects to my USB card reader just fine.

I tried to use a type-c to micro USB adapter, it doesn't work. Maybe I have to buy a type-c otg adapt first.

May I know what brand is your adaptor? I tried a couple of OTG type-C microSD card readers, but none of them work.. it simply don't seem to be providing power to the adaptor.

I could use a mouse using:
mouse -> usb to micro usb otg from z1 compact -> micro to usb c adapter

Even this doesn't work for me. My phone seems not being able to act as USB host and not recognising anything plugged in the type-c port. My phone is rooted, not sure if it's the cause.

I use the sony type-c dual flash drive and it works flawlessly

Still not working. I used a voltage reader and found that there is no voltage coming out of the USB port, no wonder it won't detect anything. No sure if my phone is faulty (doubt it, as the port works perfectly when it is USB client) or due to setting/rom/kernel...

Do you have a pop up screen asking you what to do when you connect anything to the USB port?
BTW, my USB OTG adapter is of a brand REMAX.

no, nothing happens as if the phone does not know something is connected. but works ok when connected to another host (pc or power source)
i'm using rooted 7.1.1 stock rom

Thanks! Finally i got it to work. Sorry that I had been trying type-c usb reader instead of a true type-c otg adaptor + reader... so, it fact it would work with a type-c otg adaptor.

USB 3.0 Type-C or USB 2.0 Type-c

I know it says that Axon7 has USB 3.0 on Gemarena and Phonearena, but do all variants have USB 3.0?(U , G and Chinese)If not which one of them has USB 3.0?
I've got the Chinese variant and I wanted to make sure that it has USB 3.0 before I buy a usb 3 Type-C cable for transferring data.
And which USB 3.0 Type-C cables (5Gbps) are the best?
What about USB 3.1 cables (Gen2)(10Gbps)?Do I get any extra speed if I use them with Axon 7 since it only supports USB 3.0?

all variants have USB3. there are identical in hardware
you can't get extra speed with an USB3.1 cable
