[Q]Help! A Weird USB-OTG bug [Moto E 2015 4G][Rooted] - E 2015 Q&A, Help & Troubleshooting

I am using the 4G Variant of Moto E. It's Rooted and has the Squid Kernel flashed. I'm seeing weird problems with the OTG.
I try to connect a Wireless Keyboard and Mouse and it works perfectly fine.:angel:
But, When I connect my 2GB Pen Drive, the PD lights up but I can't Mount it in the settings. I've tried formatting the Pen Drive to many formats (FAT, FAT32, exFAT & NTFS) But none of them seem to work.
Connecting the same PD to my Xperia SP running Mahdi ROM works perfectly so there's nothing wrong with my OTG cable.
I've also tried USB OTG Helper and here's what I get when I insert the PD (in the fat32 format):
Then I tried OTG troubshooter and this is what I get:
Can someone help me to fix this problem?
PS: The description of the Squid Kernel says that it's moderately undervolted. Does that have anything to do with this problem?

Portable Harddisk to Tab

i connected a WD Essential SE portable hdd (1TB) to the Tab 10.1 via the usb adaptor and a powered usb hub. The drive is formatted to FAT32.
When powered up, the Tab shows usb storage connected but after awhile it becomes usb device unexpectedly removed. I am not able to access the portable drive at all.
Anyone can advise if there is anything I can do to make it work?
My Tab is 3G version with Android 3.1 with baseband P7500UBKG6.
Thanks.
me too...
any solution guys?
I presume you need to have a seperate power supply since the tab seems to refuse to use high-power usb devices all together.
I tried connecting my disk dock and that worked fine(uses a normal power supply on the side)
got it to work by using Broodcomb ROM and using [email protected] manager to format the harddisk to FAT32, not sure which one cause it to work. The setup is the same as before.

[Q] USB Host problems

Hi everybody!
Tried to connect to my Galaxy S II usb flash drive GOODRAM EDGE 32Gb (FAT32) but it isn't working. Also not working wireless usb mouse G-Cube G4T-10BL.
When i connect this things to my i9100 nothing is happening. Even no message from my i9100...
How can i solve this problem?
You can mount ntfs drives by loading ntfs.ko module as mentioned in this thread.

I'm not sure fat32 file system works by this method.
Also, try using different kernels like Siyah which supports ntfs/fat32 mounting.

USB OTG doesn't work

I have a USB OTG cable but it doesn't work .
I have rooted 2.3.5 rooted phone.
Do I need to enable any settings on the phone to activate it?

Define "doesn't work". What're you trying to plug into it?
Most things you plug into it will need more power, so you'll need to run them off a hub unless it's a very low-powered device like a usb memory stick.
I think the thread author was pretty clear. "Doesn't work" means that it is not working. How hard is that to understand?
Look here:

It would be great to have it back...
ROM developers, can you do it?
Thanks

I am having the same problem.
Got my cable today and can´t get it to work.
Nothing shows when i connect pen drives, tried 3.
I am using 2.3.5 XWKJ1, ROOTED
THANKS.
I read from somewhere that 2.3.5 took away OTG support. You have to use a ROM that supports it. Also, if you want to mount a NTFS partition, you need the fuse.ko specifically compiled for your kernel version. For instance, Siyahkernel comes with its own fuse.ko. The regular fuse.ko you find in this forum would work for he CF-root kernel while none is compiled for the TWD kernel yet. FAT32 should mount automatically.
It works for me. Except NTFS files won't show up in gallery automatically. I have to use es file explorer to open.

Thanks for helping.
Looking around can´t find a rom that says OTG working or 2.3.5 does not support usb OTG.
I´ll try to install 2.3.3 to see if works or the cable i have got might be faulty.
As far as I know every custom rom except the stock rom will support OTG, at least for FAT32-formated sticks. USB sticks work for me in both NTFS and FAT32. I attempted to mount a solid state drive but failed. The SSD light is lit only for half a second. I guess the phone doesn't have enough juice to power a SSD. I haven't tried putting it in an enclosure that supports external power though.

Buy a SATA to USB converter, and connect the USB one to your phone.
Then you connect the power connection of your SSD to your PC, start up your PC and it must work

I tried that. It seems sata to USB converters are not supported by galaxy either.
I have a stock 2.3.4 SGII, rooted.
Sata2USB works, as long as the phone doesn`t have to power the device. If I use one of those USB cables that has 2 connectors on one end (1 is for additional power) and let the PC power the USB device, the phone works perfectly with external HDDs.
I haven`t tested NTFS yet, but it works perfectly withg FAT32, ext 2/3/4, either on usb drives or external HDDs.
The only problem is that non-FAT32 partitions must be manually mounted.

How to Enable OTG?

how do i enable the OTG mode on the Galaxy SII running android 4.0.4 (resurrection remix ICS 1.8 ROM) and i have a kernal that claims its working with OTG ( http://forum.xda-developers.com/showthread.php?t=1574672&highlight=otg ) but when i connect my cable and usb stick ( tried other devices) nothing happens! any help would be much appreciated
I just acquired a 'micro-B USB OTG' cable myself (a cheap knock-off from eBay).
As far as USB drives are concerned, I have found that I must insert a USB thumb drive into the cable before inserting the cable into my GS2. Otherwise it will not be recognized.
When inserting the cable + thumb-drive I get these two messages:
"USB connector connected" immediately followed by
"USB Mass storage connected"
and I am able to use the USB drive.
I have successfully been able to connect a 1 GB Kingston DataTraveler II, but - oddly - not a 4GB Kingston DataTraveler. An unmarked 8GB USB drive was also recognized.
I have not been able to connect: a Microsoft Comfort Curve Keyboard 2000 v.1.0 (not that I need it, but just to see if it would); and neither an HP mouse. For previous versions of Android (before ICS) you can easily find information of users successfully connecting all sorts of things including keyboards, mice, and larger hard drives.
A few other important issues are:
- File format for drives must be FAT32
- Before removing the cable+drive, remember to unmount drives by opening the notification area and click on "USB mass storage connected".
that helped me out.....not what so ever.
what is OTG btw?
On-The-Go, lets you plug in USB devices like mice , keyboards, and usb sticks into your phone like a computer

If the USB is partitioned as FAT32 a nifty notification will show and you can press that and then browse.
However, if the USB is partitioned as NTFS, you should open a file manager with root access (Root Explorer or ES File manager to name a few) and browse to /mnt/ntfs/ and you should see your files there.
Note: Am only assuming this is the mount point, since looking at the kernel you are using, he mentioned gokhan for the USB OTG and I am using his kernel (Siyah)

Is OTG working consistently for you?

I bought and returned this tablet in the first week it came out because my unit appeared to be missing OTG functionality. I used it with 2 different USB-C to USB adapters and could not make it work.
At the time, a couple of senior members on XDA got OTG to work so I assumed I had a bad unit. Since it's been about a month since it's out, wanted to find out if others have consistently been able to get OTG to work. I see from other posts that usb-to-HDMI does not work, but have all of you been able to use OTG to connect to usb drives? If so, could you share which adapters you are using? Thanks..
I was having some OTG USB 3.0 issues, the sticks worked on my OnePlus 3, but were not detected by the tablet... had me worried, but it was simply a case of reformatting the USB sticks on my PC and it all worked again.
I have 2 different USB3-to-USBC OTG adapters and both work w/o any problems on my S3. I've used them for thumb dives (USB2) and USB wireless mice. Unfortunately I cannot recall their specific model numbers as I've had them both for 6+ months, but their brand is stamped on them. One is a white Insignia that I probably bought at Best Buy and the other is a black "Cable Creation".
No matter which brand of usb stick. The only important thing is file format. I don't known for the Tab S3, but at this day all Samsung smartphones and tablets I've tested only recognize FAT32 and EXFAT file format. I've tested this on Galaxy S4 S5 S5 Mini S7 J5 and TAB S S2 S2 VE A10.1 2016.
NTFS file format is NOT recognized BUT on some devices you can read it with ES FILE EXPLORER (maybe other file browsers too but I didn't try them).
For me if you don't root your device, the only two limitations on Samsung devices weres unability to read NTFS and no DTS and AC3 audio CODEC.
Both problems can be solved, NTFS by ES FILE EXPLORER, and DTS/AC3 by MX PLAYER CUSTOM CODEC which can be found on XDA Developpers.
Greetings to XDA!
I've tested USB OTG on Galaxy Tab S3: like other Samsung devices it reads FAT32 and ExFAT file formats but doesn't recognize NTFS.
Anyway like I've told before you can use ES FILE EXPLORER to access to NTFS USB drives.

IIRC, OCZ usb drives were notorious.

"OTG" is not a brand.
It means "On The Go".
Any brand can work with the right file format.
It's the same with USB micro SD cards.
I just got a usb-c otg cable today & was trying a few usb drives and ssds with the tab s3. All worked except one of the ssd's (exFAT). It appeared to be not getting enough enough power from the usb port. I charged the tab to full & re-tried the failing ssd: it then worked. For what it's worth I'd noticed similar behaviour with the same ssd on a tab s2: sometimes it would work, sometimes I'd have to connect a usb power bank using a usb y splitter cable. My tab s3 firmware is AQBB and rooted.

Has anyone here been able to get OTG-External NTFS HDD detection and mounting to work with this kernel that is said to have NTFS support in its kernel (I know by default, it's only ExFat/Fat32):
[SM-T820,825] Flash-Kernel V.1.1 Permissive, Wifi Fixed [NTFS + USB-OTG Support]
https://forum.xda-developers.com/ga.../sm-t825-flash-kernel-0-1-permissive-t3692328
Since this kernel has SE Linux permissive permissions, I thought Stickmount Pro-Root would work but all it does is detect the drives to mount but then samsung disables them as corrupt and switches to charging mode.
I outlined in much more detail in comments: #23, #25, #27 in the link above - I wanted to get MX Player Pro to load and play my media found on the external NTFS drives that are on a powered USB hub and USB-C OTG. I could easily do this with over 20TB's of multiple external NTFS hdd's on my 2012 Nexus and other nexus/motorola devices. The OTG-C cables I have (2 different that I use) are fine as they work on the other non-samsung devices.
There are other custom ROM's for the galaxy tab s2 which can mount NTFS hdd's like above. Hopefully we can get some others to share their experience and knowledge to troubleshoot.
