stickmount + usb flash drive

I bought a 32gb SanDisk Cruzer Fit to store my music library on, and it worked initially with USBOTG and stickmount. However, it no longer works with Nexus 7, all other memory sticks are fine, and the SanDisk works on my PC, but not the Nexus 7. Anyway, I plugged it into a USB hub and it works again, but only through the USB hub. Anyone else noticed this kind of behavior? I'm guessing it's related to power draw, as the hub is mains powered, but I'm surprised it can't cope with a flash drive. I'm now wondering whether to buy another device, or whether the same thing will happen.

I had the something similar and a reboot fixed the issue for me. I tried plugging in my 250GB WD Passport but I guess there wasn't enough power for the external drive because it kinda just sat and clicked. I then tried plugging in my 16GB thumb drive that I know worked the day before but now matter what I did, I could not get it to mount through StickMount. I rebooted the Nexus7 and I was then able to use my thumb drive again. Not exactly the same but try a reboot if you haven't already.

I also have that problem with my Buffalo USB hard drive, where it sits and clicks, it's OK via the hub, but not direct. A reboot doesn't make any difference. I'm wondering if it's my USBOTG cable, as that's the only variable, I have read that others have got the SanDisk 32gb to work with the Nexus 7. I'll try another cable...

Got my new USBOTG cable, and the Sandisk 32gb now works. My external HDD still doesn't work (unless plugged into hub), but that's not too surprising. The new cable is this:-
Afunta(tm) USB 2.0 A Female to Micro B Male Adapter Cable (search on amazon.co.uk)
The old one works with most of my USB sticks, but is maybe not as solid in terms of build quality, as the new one is much tighter. The old cable is this:-

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.

[Q] U.S. USB host problems t-mobile

Hello. Had my note 4 since release and just now trying to use usb host / otg and having no luck. Absolutely no devices are working on my note 4. Tried the otg adapter on my nexus 10 and its fine so unless there is a special adapter needed for the note 4 the otg cable is not the problem. I have tried a xbox controller a mous and a thumb drive and nothing not even led lights showing activation.
So any advice or is my usb port bad? Been using vanilla android for a while (nexus devices) is there a setting im not use to maybe?

solved
It appears my motorola otg is not compatable with the note 4. Tried a samsung otg and all works. Guess not all cables are equal?

Nagging issue with OTG Thumb drives (not detected)

So this wasn't always a problem, and I can't say when it happened, but it has begun to annoy me more recently.
OTG storage used to work. Something like six months ago my Galaxy S7 Edge (Android 8.0.0, Verizon, Developer Options Enabled) stopped recognizing when I plugged OTG storage devices into the phone.
The two USB thumb drives I primarily use are:
SanDisk, 128 GB Ultra Dual USB Drive (USB 3.0 / Micro USB), formatted ExFat32
--> This is not detected when directly plugged into the micro USB on the phone, nor when connected by USB OTG cable
SanDisk, 32GB Ultra Dual USB-C Drive (USB 3.1 / USB-C), formatted Fat32
--> This I can only connect with an OTG cable, not detected
Both of the drives work on Samsung Galaxy Tab S2 and Tab S4 (I got the Tab S4 for Christmas).
The only way I can easily get files onto the S7 Edge is by connecting it by USB to a laptop.
I don't see any settings that would turn on or off OTG Storage in the settings. I don't want to reformat the drives, I've tried that many times.
Does anyone have any suggestions as to what might be keeping them from being detected? I have the pro versions of ES File Explorer and Solid Explorer both on the phone.
Thanks,
Joe

Hey Joe, I realize this is almost a year old but did you ever find a solution? I've just formatted my DUAL USB (128GB) to exFAT and it is no longer recognized by my Galaxy S7 Edge. Any hints greatly appreciated. Cheers, Scott

I have not been able to get the S7 Edge to recognize external storage / USB togo memory. I gave up trying; transfer files directly from pc to the phone now. I assumed it was a software update that killed usb memory access, but never was able to confirm.
Sorry,
Joe

Yoga Book YB1-91L USB port problem

Hello everybody. Asking for help and suggestions. Maybe LENOVO representative take notice. Have secondhand yoga book. Resolved almost all problems but micro USB port. First of all, charging device died out. Find 30-watt charger with QC 3.0 and charge now working perfectly. Next tried to connect mouse, usb hub and usb dongle. Each time got DEVICE NOT RECOGNIZED message. Got error in device list.
But......tried to connect external HDD with noname HDD box and it connected. Connection may work to copy, install files or disk may disconnect randomly.
Tried system restore, tried to change drivers ( intel drivers for chipset not avaliable now) with no luck. Think problem is with low port current, but even small mouse and dongle make error and non-SSD HDD work 9 times out of 10. Have anybody experience problems with connecting devices to micro USB port?
Tried 3 different OTG cables and OTG micro USB to USB dongles. No luck.

Maybe the port is corrupted or desoldered

I did change it with the warranty I had. I had the same problem and did not want to fix by myself as the warranty was still active
