Hello!
I must ask it for you, as simply could not solve the problem for some weeks...
Im not sure in it, but from aprox. my Gingerbread update (first day when JPQ announced here at XDA... long time ago, just had no time for care about my problem...), the USB transfer speed dropped to aprox. 3-4M/s from 8-10M/s as write speed. With this rate I simply could not use my Tab for movie player, and dont know what is the problem.
I tried to change my Sam's USB driver from SuperOneClick boundle to the latest Kies version, but not helped (I thought maybe the SPOC driver is wrong, but not...) I tried it on 3 different computer, with driver in the latest Kies but on all I have this problem. What Im sure that before GB update my transfer speed was aprox more then 2 times faster, for write on the device... Im not sure that the problem is about GB update, but sure that before it was fast, and after become slow...
Could anybody help me? Maybe any tip what soft could make this problem, before I try a factory reset?...
Lot of thanks for it...

You are activating USB UMS over USB debugging deactivate USB debugging and activate Mass Storage in USB connectivity and you should get your speeds back.

Thanks for the tip I was glad to hear it, but sadly it not helped on me. I used USB debugging on all my Android devices always and was never any speed problem, but (now) I tried to switch it off, and just use normal mass storage connection. My transfer speed in this case still 3-4M what is horrible slow...
Any other opinion, tip on my problem?
hey guys! does anyone tried this functions on razr i?
theres no wifi direct option...
havent tried otg
No USB-OTG @stock. If I plug and USB stock, nothing appends
Maybe with something like Stickmount
About Wi-Di, as it's an Intel Device, maybe can we hope some support on day. I don't know if the Medfield SoC is WiDi compliant.
The Lenovo K800 is WiDi, no reason that the Razr i will no be..
I am so longing for USB OTG.... can't wait to use DSLR Controller with this cell phone.
:/
Maybe Motorola will release a ROM that includes USB Host functionality?

Mmmh, still no USB OTG with JB.... dammit
I've heard OTG doesn't work because the razr I as it doesn't output any power and usb devices need power, I have ordered a lead which has a separate lead to supply power to the usb device and I'll update when I receive it and have tested.

So the lead came and to my sadness doesn't work for my razr I :'(
I was looking forward to that too

I'm currently using an powered OTG cable to connect my mouse and keyboard on my xt890.
the pen drive is not working im gonna test some mods on that,
OTG is working but only devices like mouse, keyboard, pad etc. USB drives doesn't work cause kernel has no option for that. To use OTG You need to connect devices through powered USB hub.

For WifFi Direct you can use this app : SuperBeam
Cheers
I tried it but failed to connect with Galaxy Mini II.
Did you switch on your WiFi ? Even for me it works only on certain devices but most of the time I forget to turn on the WiFi.
Yes I did. :/ It fails starting to transfer file.
Hmm. That's weird. Maybe you could try their IP Address method. I'll have to get back to you later because I don't a spare android smartphone. If it works I'll give you a description of what to do. Maybe its the new upate that's causing it. You could also try an older version of the app.
Hi all,
Since a few days I am the proud owner of a Xperia Z, coming from years and years of iphones, it's a huge relief.
I am however struggling with one issue :crying:
For your info, the phone has the original ROM
I bought myself a Sandisk 16GB SDHC card, to put my music on.
However when I connect my phone to my WIN7 laptop, nothing happens. No device seems te be detected.
I have installed the Sony PC Companion software, but it does not detect any phone at all.
The phone however is charging via USB.
I have tried both available USB modes MTP and MSC but I can't get it to work.
Any clues?
probably drivers issue, maybe you could try downloading the drivers from the official sony website. I am not really sure its just an educated guess as they say

I'm having a similar issue myself mate. For some reason a while ago my PC decided it didn't like connecting my phones anymore. So now. All the issues. Trying to sort them out now with removing old drivers. Installing new ones. All painful crap.
Maybe this has nothing to do with it but:
My PC will not read my Xperia Z its SD \ Internal memory when it is on lockscreen. (PIN code I use)
It only charges the phone in this state, when you unlock the phone the drives show up.
(Ofcourse also when I connect it unlocked.)
Kind regards, Stefan.

Sure, driver problem! Does PCC show 'connecting to device' when it's connected? (although it doesn't show in pcc)

It turned out to be a cable problem, one of the pins was bent.

it s because of driver installation that windows sometimes get problem.
so u should check it inside windows.
First;
Try to change USB mode, turn off firewall and change USB ports
Second;
HERE's THE SOLUTION:
Go to the Registry Editor (Start --> Run --> "regedit" --> [ENTER])
Search the following key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\
If you click one of the few subkeys in class (e.g. {4D36E965-E325-11CE-BFC1-08002BE10318}) you'll find the string value (Standard) on the right side with a value (e.g. DVD/CD-ROM-Drives)
You have to find the value "Portable Devices" on the string value (Standard) (In my case {EEC5AD98-8080-425f-922A-DABF3DE3F69A}, but I don't know if they are called always the same.
Once found, you see a string value called UpperFilters --> DELETE IT!
Finished! Now your Samsung Mobile MTP Device should be recognized and even installed correctly right away. (The name of the device changed to GT-I9100 (Devicemanager) in my case...)

Hi, I m an IT guy that has run out of ideas. I would like to ask you some questions about a (probably hardware realted) problem that i have. All started suddenly , from one day to another all usb ports, camera and bluetooth stoped working. I dont really care about the bluetooth and the camera, the only thing i care about are the usb ports. I 've checked them with a multimeter (only the pins that provide power) and the strange thing is that they do provide power. If i connect something like a usb flash drive , the led flashes (stays on , doesnt flickers) but nothing happens. I am sure that's not a drivers problem because the laptop doesnt even recognize them in UEFI nor CSM. My UEFI does not have an option to completely disable usb ports, only to change from usb 2 to 3 (no change at all). I m sure it's now a power problem, i ve reseted the bios even by the motherboard jumper.So the question is , what it may be? is it a motherboard malfuction ? Can it be fixed? Also , is there any possibility that for example the camera is faulty , or the camera cable , and shortcutting something? (i mean if i disconnect the camera and the bluetooth, is there any possibility that it will be fixed? ) thanks in advance.
p.s. also on the motherboard there isnt anything strange like a blown up resistor or something.

thanks in advance

Though the Forum does not really provide PC/Laptop support unless it's related to the Android type of devices so there's really a limited amount of information regarding them specifically.
With that stated...
The following thread is probably the best place to ask this question.

Hi everyone
here I've got a terrible issue with my note 8 and SAMSUNG USB OTG.
When I connect my otg and a flash memory to phone, nothing happens, unless you force restart the phone while the otg is connected. After booting I can access to my flash memory but after removing the otg and reconnecting it, again nothing happens unless force restarting.
I've tried everything possible. Downgrading, upgrading, 4 files rom, pit file, rom from different zones, but still have the problem. I have no other issues regarding the USB port and charging, fast charging, connection to computer and any other stuff works fun but this OTG.
I wanted to know if anyone have any solutions for my problem or if anyone had the same issue or not.
it is also worth to mention that I have not rooted my phone due to warranty issues, and for that I haven't tested any kernels.
thanks for everyone

That isn't right... As soon as I plug in my OTG USB key it detects it, no restart required.

allow file transfer .... possible
Nope, I have developer options enabled but debugging isn't on. never had to enable file transfer.
When I plug in the OTG device I see a usb icon in the notification panel. Swipe down and pick explore. Mind you it only opens in the stock file explorer, I did have another file explorer that picked it up too but can't think what it is and it has been lost myriad of other apps I test and play with...
Just be aware that it may take a few seconds to scan the device,depending on size, and then display the icon.

i know it sounds weird but from past experience flaky USB drives are more trouble than they are worth, from first hand experience i know patriot, corsair and sandisk work well as OTG drive
also you neglected to mention the file system the USB was formatted with, i believe only FAT, FAT32 and exFAT are supported

also possible that the phone doesn't like your OTG adapter. I bought a usb 2.0 to type C adapter which doesn't even work on the phone - when I plug it in usually the moisture sensor error comes up saying water is in the device and I should let it dry. Unplug the OTG and the error goes away.
So... I bought a USB 3.0 A to type C OTG adapter and that one works fine with everything I've tested (usb flash drives, keyboard, usb ethernet adapter, etc)
I believe the USB-C to USB-A adapter that came with the phone is actually an OTG adapter (tested xbox360 controller and keyboard)
I also believe that the note8 can host usb flash drive native (no need for OTG cable) as i have a dual head USB-C and USB-A flash drive which is recognized once the USB-C end is plugged in

also reconnect and again connected but no answer
only with force restart
Sorry to dredge up a semi old thread, but has anyone found a fix for this?
I'm having almost the same issue, I finally decided to try out the OTG adapter from the box and nothing works, it isn't even recognized. Tried ps4 controller, mouse, keyboard 2 different thumb drives. Can't figure out what the deals is.
Other than that pc connection seems to work and charging works fine. TIA
I'm having a similar problem. A month ago, used both OTG adapters (original from Samsung and a generic one) it detects my memory sticks as a hard-disk and was able to manage my files. But since a couple of weeks ago it does not detect them anymore. Is like it did not supply charger to them anymore. I have tried the USB debugging menu and no difference at all. Even I got back to factory reset expecting to solve the issues but nothing happened. The port as such is working perfectly because I'm able to charge through it. On the other hand, Samsung DEX is not working as well. It just charges the phone but never boot-up.
I'm just waiting for Oreo and hopes this will sort the problems out.

That sounds like a bodged port to me man
Is there any dust or dirt in there that you can see?
I really don't think Oreo's gonna fix that for you

Seems to be a little bit dusty. Anyway, the other thing is that, when the Usb is detected it ask to choose between transfer files, images, midi device and so on, even if I choose "transfer files" mode it always get stuck as "charge connected device".
Hi i have the same problem... my note 8 can connected mith my notebook, but my otg with an usb stick cant recognize my note8. I test the same otg with usb stick on my friends phone example S8 and it detects promptly all.
I hope the fixing take not long time. I waiting for help. Greets
Well, adding one more case here, my native file manager doesn't recognize any memory connected via the original otg conector, but, using x-plore file manager, problem solved, as I use x-plore since my symbian days, I never gave this issue much importance, this problem was present also with my note 7

This. I have exactly the same experience. I bought a couple of months ago a new Note 8, and finally decided to try the OTG adapter that came in the box. Nothing worked. I tried the adapter with a friends phone and it worked like magic (USB drives, mice, keyboards, controllers, etc.).
Would really apreaciate if anyone can provide help on this issue... Cheers!
