A few months ago, my RN2 Prime wouldn't charge so I changed the USB board with the one shown in the attached photo. I can now charge my phone and transfer files to and from my pc but my phone can't detect any flash drive attached to it with an OTG adapter. All the flash drives and the OTG adapter work as expected on my wifes phone, which is also a RN2 Prime. Does anyone know whether the lack of OTG function is likely to be caused by this replacement board or by something else ?
Maybe fix your usb otg with tutorial here hxxp://hp-cdma.blogspot.co.id/2017/04/mengatasi-masalah-usb-otg-pada-redmi.html?m=1

Hi guys,
Just found my A70 can't connect to the USB Storage via OTG cable. Seems not detect. Have you meet this kinds of issue?
The obvious question is - are you sure you've got the right cable, I have cables that physically fit and work for some other devices - just not this archos
Even you've got the right USB host cable, e.g. the Nokia CA-157, you may still face compatibility problem. Many digital cameras will be detected automatically if connected. However for other USB mass storage devices, e.g. flash drives or card readers, only a few will work. We all hope that Archos fix this in its next firmware update.

try to connect an usb-hub and plug your usb-storage into it...that helped me
a problem exist on this firmware with Archos 7.0
Archos knows this problem
see that with the beta firmware

My bet is on power usage. If cable is working than probably device it self drains more than declared 100mA when plugged in. Even if device is rated under 100mA it might more than that when starting.
Just test it, I upgrade to 2.0.71 today, but the A70 still can't detect the USB Storage device...but it really very smoothly right now
Keep in mind that the USB drive needs to have an external power source in the case of an HDD, a flash drive should be fine running off the power of the device tho
hi XDA
I am having some strange behaviour with my USB OTG...
- charges OK
- connect USB OTG cable: phone says "USB host cable connected"
- connect a memory card reader: nothing (used to work previously though)
- connect a mouse: nothing (used to work previously though)
- plug into official Samsung car dock: car dock enabled, but only one stereo channel working (right channel)
- plug into PC: Windows says "unrecognized device"
..... SO
I was thinking: something wrong with my hardware
so I ordered a new USB hardware module on ebay
and I successfully fitted it
...however
...still no change ???
looks like it wasnt a hardware problem after all
USB debugging on or off: no difference
Anyone got the same or similar issues? OTG is a really useful feature for me so I hope I can fix this
Try plugging the card reader or whatever into the OTG cable, then plugging the other end of the OTG cable into the SGS2. That seems to give a much more reliable connection in my experience.

It is not the first time I am trying OTG. This summer I was travelling and posted >100 pictures to my blog. The correct order was: cable first, then memory card reader WITH memory card already inserted... in desperate attempts I tried several other combinations but without luck.
i bought a usb otg from ebay he work perty fine a periode of two mounthes but now when i plug the usb otg its notifed (usb connector connected ) but there is nothing i pluged usb stick i pluged mousses keyboards nothing and i have tested that on many phones (galaxy s2 and note and s3 ) so i think the problem is in the otg how can i fix that ?
Buy a new one. They're all of five bucks.

Well you said you've tested different USB devices with it, and you've also tested it on 3 different phones. Which obviously means the cable itself is cactus.
Not really anything you can do about it.
A quick Google search for 'repair USB OTG cable" brings up a bunch of results, some of which detail how to repair USB cables (apparently). Looks like you have a lot of research/work to do if you can't buy another one then.
I've got a similar problem with OTG USB driver on SGN.
I bought OTG cable which work fine when I connect pendrive device, but doesn't work when i try to connect usb mouse, keyboard, pad ect.
It worked when I had a stock samsung software 4.0.3, but I changed it because of its battery drain problem. I've installed 4.0.4 Paranoid Android v05 (CM9). I found in Market application USB Host Controler, and itshows "S3C USB Host driver NOT found!".
Is it possible to add this driver to OS ? Or is there any other way to use external hardware device like mouse or keyboard?
I'm looking to be able to use my external HDD (1TB WD passport) on my phone via OTG. As I understand, ntfs support varies with kernels etc but I'll cross that bridge when I come to it as I think there's a more fundamental problem.
I've got an OTG cable, and my mouse, usb pen drive, keyboard etc work with it. The HDD doesn't, because the phone can't provide enough power to operate the thing. I thought I could get around this by connecting it via my usb hub (which runs off external mains power) but when I connected this up to the phone and plugged the HDD in nothing happened. Likewise, the mouse and pen drive etc could also not be recognised by the phone when they were each plugged in via the hub (one at a time, I wasn't trying to run 8 things at once!) even though they worked perfectly when the phone itself was powering them when they were directly plugged into the OTG cable (if that makes any sense).
So, assuming it was a problem with the hub, I instead tried the method in this thread http://forum.xda-developers.com/showthread.php?t=1828032 and made my own y type cable so that now rather than the phone providing power to the OTG peripheral, the power now comes from a standard USB phone charger. I'm fairly confident that I did all the soldering correctly and there weren't any short circuits.
When I tried using this, I had the same issue as with the hub. None of the mouse, the pen drive etc could be recognised with the modified OTG cable, which was odd as physically nothing had changed from the point of view of the peripheral plugged into the OTG (the data cables connecting it to the phone were unchanged, and it was still getting 5V power, just from the wall rather than my phone) which makes me think perhaps the problem is a software one where the phone only recognises a USB peripheral/begins USB host mode if the peripheral is actually draining power, since the power leads running from the phone side of the OTG cable are now just an open circuit.
Just to confirm I hadn't just snipped a data cable by accident when modifying the OTG cable, I re-soldered the OTG cable to how it originally was and it worked the same way it had previously. This means all the data cables are still intact, so I think it must be a software issue.
I thought maybe a way of testing this would be to modify the y cable and connect the red and black power cables coming out of the phone to each other via a fairly hefty resistor (so you still get power flowing from the phone even though the USB peripheral is powered by the wall). But it seems a bit dangerous!
Has anyone else had trouble with this? I've read around on forums and for a lot of people USB hubs and y type OTG cables seem to "just work", although I've not seen anyone with an i9300 reporting success. I'm running the latest version of liquidsmooth, but have also tested on CM10.1 and have the same problem. It might be an AOSP thing that stock samsung firmware will fix?
Let me know your experiences!
TLDR: I'm pretty sure I've got a software issue where my i9300 only recognises a USB peripheral/begins USB host mode via OTG if the peripheral is actually draining the phone's power, and so doesn't work when a USB hub or externally powered (y type) OTG cable is being used.
Thank you!
It apparently only supports 500GB regardless of power source

Really? That's odd - is that an android limitation or samsung? Either way it still seems weird that my y cable/hub didn't work for the mouse/keyboard, is that something you'd expect?
Sorry I didn't read that part.
I have a portable passive hub. Kb and mouse working fine...

Hi everyone, I'm looking into getting the Mate 2 to use as a car tablet (I know its kind of small, but its what will fit in my car). What I am trying to figure out is if the Mate 2 will charge with an OTG cable, as I want to use a USB flash drive for media, and possibly a USB DAC. I've been reading that it requires an OTG cable modified with a 36kohm resistor somewhere in the cable (which I haven't figured out where) and a modified kernel, but nothing specifically for Huawei phones/tablets. Does anyone have any insight for this phone?
Thanks!
