[Q] Help with Connecting to Computer

I need help with mounting my phone. I'm currently running CM6 and last night I USB tethered the thing for the first time. It worked and everything, but now when I connect my phone via USB and try to mount it the computer doesn't recognize it, well it does recognize it as a network adapter (HTC Remote NDIS Device #2). Please help, I'm trying to remove the battery tweak but it would also be nice to be able to mount my phone again. Thanks all.
Make sure you have "debugging on" and "charge only" when connecting your phone. If those two things are not your problem, try uninstalling HTC sync and drivers, reboot your computer and reinstall HTC sync.
I'm having a hard time finding "debugging on" and "charge only" options in CM6. Where should I look. I also have not been able to mount my SD Card on My Computer since the install.
Thanks.
Reboot your phone. Known bug with cm. You can't usb tether and connect drive/adb at the same time period, but cm6 gets stuck till you reboot. Easiest solution, google wired tether for root users. Lets you usb tether but starts the other drivers up fine when you're done so no reboots needed.
Oh, and charging only is not an option on cm6, that's the default anyway, you always have to manually mount sd. Debugging is in settings/applications/development

[Q] Galaxy Note wont connect to pc

Hello forum !
i have used a couple of hours now trying to find a solution to my problem both here on the site but also on the internets.
i just recently became the happy owner of a Note, but i have been completely unable to connect it to any of my pc's ive had a galaxy i9000 that i didnt have any problems with but with my note it wont work.
under win7 64bit - when i plug the usb cable a "boc opens" in the drop down menu called MTP and when i klick that nothing happens, ive trid the varies ways of removing the sd card unmounting it etc. and debugging and so on but wont work.
it randomly connected once but then it dissapeared from my computer.
under winXP 32bit it just says usb device not recognised, i really wanna root this thing so i can play with the true power of this amazing device.
and on both pc's ive tried with kies and driver packs both together and seperately.
anyone out there that can help me out with this problem ?
cheers
and happy new year

Before connecting it to the PC with the cable, click "connect storage to pc" in the USB settings. After clicking it, then it will ask you to connect to pc. If you connect to pc before clicking it will not connect.

Hello i have done that but the same happens ive done it like it says i should i just dont get why my pc wont recognise it , when i press it and then it waits for me to plug it in, i do that the dialogue box shuts and then nothing happens besides windows saying unrecognised device connected
Strange, Mine connect fine just like how marinervijay mentioned. Go to Settings > Wireless> Usb Utilities and press connect first and then insert your USB, then press connect USB. Voila. There should be a window prompting to open in your windows just like when u insert a flashdrive to ur computer.
iknow its supposed to work like that.
the problem is that it doesnt work :/
Okay, have u tried resetting your Note to factory default?
no i havent tried that, because its all new it didnt work since i got it, i never thought that that might help, ill give it a go.
thx
On another, you might have a defective USB given to you by ur retailer. Perhaps you can contact them somehow and ask them to replace your USB?
do you mean the USB cable delivered with the phone ?
Cheers
Yes. Could be a defect. I'd suggest you check with your retailer if it is replaceable if none of what mentioned is working for you.
Hi,
Have you ticked USB debugging? Its under Settings>Apps>Development
Then it should show usb connection in notification tab, tap it and set usb storage as on.
There may be few problems here so I will suggest different solutions, one might work for you
1. Turn off your antivirus and connect, it should work, see after connecting mobile that does it install something near "Bottom clock"?, open "my computer" see if it gives you N7000 (give it a minute). sometimes your computer settings are a problem
2. If no, Install latest Kies on your computer as it downloads Samsung drivers for your phone
3. after connecting 1st time, computer takes some time to recognize your mobile--be patient--
4. if all of above doesnot work, restart computer, connect USB to another (or same) port (turn off antivirus) and see
5. Nothing, try in Setting>Applications>Development>debugging Mode
6. if not, try on another computer
7. still does not connect, change USB cable
8. Still nothing there might be a issue with your device, but I will not conceive that every quickly, trying all above few times should resolve the issue..
7.

Okey ive tried them all now, more then a few times most of these ive tried already and the antivirus isnt an issue as i dont have any on this pc. i think the problem either lays at the usb cable or the device itself. i will try and get to borrow a cable from a friend or something
Cheers for all the replies and helpfull inputs
Happy new year to everyone ^^

Hey,
I am able to get USB storage, and I got root access thru the batch files and help provided in this link: http://forum.xda-developers.com/showthread.php?t=1329360
I have Kies installed and this probably helped detect the phone.
Hope this helps..
USb Problem
Hi I've had the same problem.
I have been using the Note quite happily as a Mass USB storage since early December. Plugged it in this morning and I don't get anything. I have also tried the debugging and all the other things listed. Here's what I get:
Usb debugging on - just a sound and a charging indication
Usb debugging off -usb connected Mtp connected on the notification pull down page. When I click on notification it just shuts the window.
I have tried dialling *#7284# and selecting USB PDA which didin't do anything for me but others seem to have had some luck. See this link:
blog.vacs.fr/index.php?post/2010/12/24/How-to-repair-the-USB-not-detected-problem-on-Android-Samsung-phones
I will be rebooting tonight but I don't really want to.
only the Samsung USB wire works
I had this problem today. The Note would never connect the USB or external storage. I searched and found this thread.
I then noticed it was another USB cable (I gave about 1,000 now!). I tried the Samsung one, and it worked first time.
It is annoying, because these cables are normally swappable with any device. It appears Samsung have defined their own standard. The great thing about standards, of course, is that there are some many to choose from!
USB cable was defect - and replaced
Thanks for the help everyone

won't stay connected to pc

My sons got two hd+'s for xmas and I'm in the process of attempting to connect through adb, which I have done many times with v various phones, yet when I plug the nook in I hear and see it connect and then immediately disconnect over and over again. Ideas?
It seems its only when I'm in usb debugging mode. Both are doing it.
I've rooted, installed GAPPS and so on many Nook HD+ tablets; most for my friends, since they have no idea how to do it. I've noticed this problem occurs due to the Nook not being installed correctly in ADB mode.
What I would recommend is going into Device Manager, find "Android Composite ADB Interface" and make sure it has a green-chip-like icon on the bottom left corner of the icon. If not, then it's not functional. To solve this, once your tablet is connected, it should be detected as a media player/portable device, with the name BNTV600 (I think it is/was - all this is still in Device Manager by the way). Right click on the device, and attempt to change the portable media player into a "USB Composite" device. That should solve the trick.
If you're still having problems, I can connect to you via TeamViewer remotely to access your computer, whilst your tablet is connected and solve the problem for you (if I can). If you'd like, I can completely root your tablet for you. I've done it for a couple of friends over TeamViewer, so if you'd like, I can do it for you too.
Best of luck.
P.S. Try disabling "USB Debugging" mode and set "Enable ADB".

Note 5 does not fast charge mode or detect otg

Excellent day to everyone, I request your help please.
I have note 5, Android 6.0.1, everything worked excellent but from one moment to another it does not go into fast charge mode and when connecting devices otg only tells me in popup window connected USB device but it does not open the micro SD connected to the adapter.
Obviously, I already tried the charger and the cable in another note 5 and it works perfectly. I also did center of charge cleaning but nothing.
I installed the application called USB host check and the following appears on the screen;
android.hardware.usb.host.xml
okay
handheld_core_hardware.xml
USB host not enabled
tablet_core_hardware.xml
not found
Apparently the same application can search the necessary files and write them in the relevant path. The problem is that I do not have root so I can not write to internal system.
No can do root because the pc does not detect the phone even activating USB debugging.
Any ideas? If I restart the phone to factory with all its wipes will be solved?
Is there any way to do root with no computer involved?
I thank you for your contributions and if any information I lacked to mention I beg you to tell me which to see if we can take it forward.
In advance, thank you everyone.

USB connection to PC - only charging

Dear All,
Yesterday I switched on my old Pixel 4a5G then connected to the PC and... nothing happened.
I dont have any notification on Windows (even on Ubuntu) about new device (checked also device manager) and the same on the Pixel.
Phone only charged.
I decided to check another cables and I had the same result. I even bought new cable USB Ato C 3.2 gen 1 and still nothing only charging.
I checked on another PC the same - only charging my device and no connection. Of course I switched on usb debugging on Developer Mode and USB/Android Auto File Transfer option, even PTP doesen't work.
So I had:
- no notification about USB connection on the Pixel
- no notification about new device on the Windows (missing sound , no device Android or another name in Device Manager on the Windows)
I switched Pixel in safe mode - the same result
I connected to the Pixel my WD SE protable hard drive and... I had notification about USB device, I opened it and had two options:
- This device (which was choosen)
- Connected Device
rest like File Transfer, Connection Thetering were grayed out
I choose Connected Device and there was an info "switching" and after couple seconds "cound not switch..."
If anyone had the same problems? could be software problem or USB port broken on the Pixel?
I have latest updates installed on the Pixel. I did Factory Reset but nothing changed. Even on Fastboot mode Windows didn't recognize device (no sound nothing)

Mine stopped connecting to PC after Nov2022 security update, still will not connect & Google dont want to know, they just shut threads down.
Hi !
I have had the same problem for a long time !!! No more notifications to choose it when connect my Pixel to PC !!? no Pop-up to choose "Connection, Photo Transfer, Charge, etc..."
The simplest solution is to connect the Pixel via USB to the PC/MAC then open Settings/Connected Devices/USB/ To finally access to choose "File Transfer, Connection Sharing, Midi, Etc..." menu.
Do not forget to first activate the developer mode and USB debugging.
But I don't understand why I never see the notification to choose
