OTG USB mounts, then immediately unmounts virtually every time - Onetouch Idol 3 Q&A, Help & Troubleshooting

Based on similar threads it would seem I'm not alone.
I've tried a Transcend USB 3 SD card reader; although 3.0, it works flawlessly on LG G Pad running KK so not a power draw issue; I've tried an OLD 512MB USB thumb drive to be sure, same; I've tried two different OTG cables (admittedly same cord brand purchased together, but again flawless on gPad).
Mount --> Unmount.
Do many of us just have OTG dud Idol 3s? It's always been this way. Wonder if Alcatel would give me a RMA, seems unlikely. :/

[Q] G Tablet Reboot with External HDD

Hello,
I thought I'd try and see if anyone else is having a similar issue.
I recently picked up a western digital 500GB passport external hard drive.
I formatted the hard drive to fat32 and double checked there are no extra partitions on the drive.
I'm mostly running CyanogenMod 7 with stock kernal lately and I've found when I hook up the hard drive, the tablet stutters a bit and then reboots.
On bootup it gets to the unlock screen, and when it starts scanning the sd card, the scanning message starts to cycle quickly and the tablet reboots again.
I restored to a backup of vegan5.1 to test on it. Same thing, on insert the tablet starts to hang and reboots.
On vegan though, on the next reboot, it would start normally, but for some reason its not mounting the drive. I search under usbdrive and don't see the folder and file i put on it for testing.
Anyone else having issues like this? Could the problem be its a 2.5" drive and no external power? I know when its hooked up, the light comes on and I can feel the drive spin up and vibrating, so not sure whats going on.
Thanks for the help
That (not enough power) sounds exactly like what's happening, I.e., the drive is drawing so much current from USB that it's either causing voltage to the gtab internals to drop to the point that it resets.
Jim
If this is the case, does anyone know what 2.5" external hdd's will work with the power requirements? (Someone who has one that does work?)
You could always get a powered USB hub, provided that isn't too inconvenient to carry around.'
Edit - Most 2.5" external drives that didn't require external bricks that I have seen have a 2 prong USB adapter. One for data and power and the other for more power only, since each port maxes out at around 500mW I think. Obviously we have only one port, so a powered hub or a jury rig.

I think others have gotten some drives to work, but not sure if they were 500gb. Also, even w a specific model, if the current draw or voltage are just 'on the edge's of working/not working, you may or may not get lucky.
BTW, have you tried w a thicker/heavier USB cable? Thinner/smaller gauge wire has more resistance, so voltage drop would be less over a shorter, heavier gauge cable than over a longer, smaller gauge cable. I have actually had drives not work, then switched to a thicker USB cable then it worked.
Jim
On a similar note, just yesterday I purchased an external USB DVD+/-RW for use with my netbook and tablet and it would not work without a powered hub between the tab and the DVD.
My 160GB ipod classic works fine, but my 1TB external drive that has an external power source doesn't work with any of the ROMs.
Does anybody know the maximum current supplied by the GTab's USB host port?
My 2.5" 500 GB External came with only a short (single) usb A to usb mini cable.
And it gets powered up fine from every laptop/netbook I have tried. They have always displayed 500 mA max current for each port.(when I look in Windows Device Manager, USB Root Hub).
Can the G-Tab supply up to 500 mA from it's USB host port??
I want to make sure it will work on a GTab before I buy it.
confirmed working external HD on g tablet
Using tnt lite 4.2.4, i personally have a 500gb formatted in fat32 working
model 500gb free agen go flex.
I've tried the latest WD passport SE, spun up and didnt detect in astro, ES file explore or stock file viewer
i have over 100gigs on this drive, about 80 of music and some Tosh.0 and everything pops up instantly and runs all the music fine out of MORTY music player... plays perfectly. Must have for your powerhouse. Hope this answers all the unanswered questions about external HD's on g tablet.
I have not tried stock rom or any other roms.
If you are looking for different external hard drives... make sure they are LOW POWER and NOT 3.0. 3.0 seems to require a driver to work. So its kinda hard to walk into a store and buy 2.0 only devices now.
Goodluck all.... i was using a patriot xt 64gb rage flash drive before this but 130 bucks is outrageous vs 75 i paid for the 500gb seagate.

[Q] Hard Drives Compatible With USB ?

Does anyone know what the requirements/limits are for using a hard disk drive with the dock USB port ?
I am thinking about getting one of these for general purpose external storage, and it would be nice to get one that works with my transformer too.

well there is no usb 3.0 support so those are out unless you get a backwards compatible one. And you also have to check the power consumption i think it hase to be bellow 15volts but im not sure
As far as I know all USB 3.0 drives are backward compatible.
from what i have read most are compatible with highspeed usb 2.0 but allot less are compatible with regular 2.0 hubs

What. There are 4 kinds of USB (not counting on the go, wireless and eventually others) : USB 1.0, USB 1.1, USB 2.0 and USB 3.0
Hi-Speed USB means just USB 2.0, Super Speed is USB 3.0 and the older ones are plain and simply USB.
The theorical top speeds are: 1.5mbps, 12mbps, 480mbps and finally 4000mbps
High speed was briefly and not standardized with USB 1.1 so some device makers had that nonsense on their hubs.
Maybe you misunderstood? Some drives don't like some hubs, but that's a power requirement... If the drive needs x volts and the hub can't offer them because it's already sharing the power with other devices and has no wall plug to get extra power, the drive will just spin up and down without ever starting. 3.5" drives always need their own power adapter, so those always work, 2.5" ones usually draw the power from the USB and as such might be a little hit and miss with hubs, however the Transformer powers them up quite well.
Western Digital makes awesome, reliable, fast and quiet drives, I do have an USB 2.0 My Passport... And several others in various devices

I wouldn't recommend any of those drives. I would instead go with something like THIS HDD, THIS external enclosure and THIS retractable USB 2.0 A-Male to Mini 5-Pin. I have this setup and I also have one with an 120gb SSD. Incidentally, if you go with a SSD there is no motor that has to spin the platters because there's no moving parts so it uses less battery power than the first HDD I showed you. Also I know on the Vantec enclosure it says capable for up to 160gb drives but if you look at the details it says up to 750gb HDD's. I can confirm this because mine is a 750gb HDD.
Got a Buffalostation that works well. If it's the best or not, I wouldn't know.

So far that's the most expensive and less bang for the buck option XD

Thanks everyone. So far It looks like this one is a pretty good choice. It has good reviews and if its confirmed working on the Transformer I might go ahead and grab it.
Hope it'll serve you well.
I just remembered that I had to re-format it to NTFS before the Transformer would recognize it. Just thought I'd let you know.

...but extremely dependable, very effective and lower power consuming than any of those Buffalo drives. I have a Buffalo NAS drive and they're good for that but as for using one for a portable drive I would not. If you're going to use a regular HDD I would at least go with a Seagate or Western Digital drive as they tend to be better drives and are far quieter than any other brand on the market today. Yeah it may be a little more expensive but it's worth it. At least it was for me that is.
i have a 350g western digital that ive had forever.
This drive arrived in the mail the other day. So far, so good; it was easily recognized by the TF. Not sure how fast it drains power as I haven't used it for too long yet, but it's silent. I also have an old 320GB Western Digital drive in an enclosure from five years ago that my TF sees, too. So, I have backups of backups. And that's not including the (2) 32gb cards I'll have once the second one shows up next week.

why 2 32g micro sd cards? i find the one 32g in the tab and a 128g in the dock work just fine, and i have my 320g external if i need more. i dont think i coud stand switching out sd cards all the time...

Only one of the cards is micro; the other is full-sized. No switching necessary.

USB OTG keeps ejecting

Hello, anybody here with an Idol 3 that keeps ejecting flash drives plugged into the micro usb using a USB OTG cable? I have used 2 flash drives and 3 OTG cables and it still keeps on ejecting by itself. Thanks.
Are those flash drives within spec? If they draw more than 500 mA @ 5V, then they are NOT in spec and hence why the drives keep dropping out. Typically that means a USB 2.0 drive should be used. Or a OTG USB drive (I have one) since those have to be in spec otherwise their OTG usefulness goes out the window).
The same flash drives and otg cables worked with all my other phones so I don't think there's any problem with them. I ended up returning the phone since I was also having problems with crappy photos in low light. I have a zenfone 2 which is pretty comparable to this phone and the photos are better in low light plus no noticeable lag unlike with the idol 3. The only thing I really liked with the idol 3 were the stereo speakers which I'm missing right now.
I dont think this phones kernel supports otg. Says USB host diagnostics. BUELLER?
I tried otg also, in 9 of 10 cases, phone reject usb, in one case connections was achieved, and i can copy files from usb. But, even in that case, after some time, connection brakes. Annoying.
5.5 idol 3 android 5.0.2 .. I have used this phones OTG with flash drive, copy move paste all work and other usb devices also work.

Can't use OTG-USB in TWRP on Grouper

Hello, I've flashed a couple of ROMs on a Nexus 7 (2012 - Grouper), using TWRP and a USB memory.
Now, when I tried to flash a new ROM, the USB OTG is no longer recognized.
I've tried two different OTG cables and a couple of double ended USB sticks, but they are not recognized.
I've also tried ADB sideload, but that didn't work either.
I've had a similar problem on other devices, so I just put the ROM on an SD card. But the Grouper doesn't have a slot for an SD card.
The same thing happened last week, but the OTG came back after navigating around in TWRP. Now it seems to have permanently gone.
Any ideas anyone?
Thanks
I'm wondering whether this could be a hardware fault, possibly due to using a faulty USB adapter some time in the pas.
Is it possible that a faulty adapter could produce a hardware fault in the tablet?
In that case, is there any way of getting a new ROM onto the tablet memory and so give the tablet (my wife's) a new lease of life? TWRP is working, but that's all. Maybe jumper leads onto the USB connector. That could work if it's just the connetor, not a softare prob. I don't suppose anyone's tried that.

Can anyone recommend a VERY small micro USB flash drive?

See, my phone (Moto X 2013) supports OTG, but does not have a micro SD slot.
It only has 16 GB of storage which has proven to fall short for my needs because I love listening to music on the go, and I have a lot of music.
Another thing is that the USB port of my phone has some short of false contact after years of use, so sometimes a little wiggle can make it disconnect, this is the main reason why I want the USB to be so small, so that when I walk with it on my pocket, it doesn't get disconnected because I touched it 'wrong'.
So that's the question, do you know of any small micro USB device (without the need of a micro USB adapter because it adds length and volume)?
Something like the Sandisk Cruze but on a micro USB form, something that looks more like the USB plug of a wireless keyboard than a USB storage device. Thank you.
As a side note, I was thinking of those phone cases that serve as external batteries, well if there was something like that but that served as a micro SD to micro USB adapter, I could use that. The thing is that I have seen no such thing for sale and even if there was, I doubt I would be able to find one for my exact phone model from 7 years ago.
