Hi everyone I'm Valerio, an Italian guy.
So sorry for my bad english in advance.
I have one big problem with my Asus Zenfone 2 ZE551ML 4gb Ram 64gb Hdd.
When I try to connect my phone to my Windows 7 Pc by Usb, it still charging. No notification alert appears on phone and also on pc start bar.
It is on charge and stop (like traditional wall battery charge).
I've already turn on usb debugging, mtp transfer allowed and tried different usb cables but nothing change.
Same thing when I try to use OTG cable. When I try to connect devices like usb storage or printer or whatelse, my phone recognize anything.
P.s. Net frameworks 4.62 and Windows Media Player 15 already installed on pc.
Anybody can help me? Thanks a lot.

Hi all. I have a problem with my tablet Archos 70 IT Rom Uruk Droid 1.6. I wanted to connect a USB stick to it. I purchased a USB host. I plugged the USB drive and a message appeared that the external memory is faulty. I thought that just the tablet on the USB input current is too small because it is only 100mA. So I bought an active USB hub. I plugged this set and the system correctly detects the stick but when copying files to the message appears: external memory has unexpectedly disconnected. I would add that in this kit - hub + active host mouse works keyboard, GSM modem Huawei E122 is not working because the tablet can not be initiated. Why stick does not work properly?On the original ROM from Archos 2.4.82 is the same situation. I should add that this happens on a few memories of mass. Regards, and please help to solve my problem. I am very tired of this situation. Thanks for any help.
Just got a Galaxy S3 a few days ago, everything was going fine. Transferring music to my phone from my MacBook Pro using Android File Transfer. Half way through the app stops transferring and I have to force quit on my laptop. Now when I reattach my usb cable I get the following message: "No Android device found Please connect your Android device with a USB cable to get started" My cable is connected, my phone is charging, but the phone is not showing that it is connected (no usb in notifications, can't choose between MTP/PTP...) So I can't continue to transfer my music I restarted both my MacBook Pro and phone. I tried to see if its my phone by connecting to my dock in my car and everything works fine, my Car Home Ultra app opens and works fine. HELP please. How can I get my phone to recognize my cpu via USB? It was working fine, but now nothing other than charging. I read on another thread too toggle USB debugging in developer options, tried both to no avail. Help please, I am an Android noob.
Is anyone else using a pci usb card and trying to connect your phone to it? It keeps connecting/disconnecting no matter if I choose MTP, camera, or mass storage. Works fine with my laptop or my other computer with working usb ports. I just want to make sure it's my damn computer what's causing this problem.
Note: I tried different cables.
Ok, so has anyone else had problems with this..
when you plug in an OTG connected usb device (i have the same problem with usb drives and midi controllers so far) and in the notification bar pull down it will say charging usb device, and when you choose to switch it to something else, like transfer files or connect a midi device, it just goes right back to charging the device after changing it for a few seconds or until you tap the screen or check it again.
This has completely stopped me from being able to connect a midi device, and causes the usb drives to get hot, although I can still transfer files in an 3rd party file manager, but the notification bar will never stay in tranfer mode, and it has never gone into midi mode at all.
This is not an issue with my OTG adapter, as I also have the same problems with borrowed adapters, as well as using DEX. In fact in dex, if I plug in a usb drive and switch to transfer files mode it will crash. Has anyone else experienced these problems? Are any of these apps for OTG management in the play store useful for this? They seem to be useless based on the reviews except for testing a UTG adapter. Thanks!
btw I don't have root, my note 8 is fully updated to BQLA version.
Hi, check the battery! If internal resistance goes up so does noise.
Check the cable and connector on the phone as well.
I've been trying to find information about this on the web but I've failed to do so.
I bought a Kingston Micro duo USB C 3.0 and it worked a couple of times (I had to manually change to MTP) using the USB C connector straight on my S9+.
I've been trying to get it working again on my phone with no luck. Everytime I connect the USB C end on my phone, it will show on the notification tray "Usb charging device" and "USB connector connected", this last one will disappear in a matter of seconds.
I've set the default to be MTP using Developer Options and even select MTP for the device once it connects, but it just reverts its status.
I know for a fact the USB C end works because I can connect it to my computer (Windows and MacOS) and I've tried formatting it using a lot of different formats, still when I connect the USB C to the device it doesn't read it.
I managed to get the drive working using my USB C dongle (Which has 2 USB A 3.0, but no power passthrough) and connecting the USB A side to it and my phone recognized the drive instantly! So I formatted the drive using my phone, connected the USB C end on the device and it doesn't recognize it.
It seems it's just a bug on the Samsung device or something. I guess Samsung is moving towards USB C but they are not thinking on all the stuff you can connect.
I found this link https://us.community.samsung.com/t5...g-defaults-to-charge-other-device/td-p/183539 and this other https://forum.xda-developers.com/galaxy-note-8/help/note-8-usb-otg-t3680207 but so far no solution.
Edit:
I just tested my drive with an S8 and it worked without issues (the USB C end) and was able to test it on another S9's and they don't recognize it.
Mine works without issue. Not sure what's happening with yours sadly. Edit - mine's the Micro Duo 3C, but I can't imagine there'd be much difference.
Same here. Today I had hard times getting to work my USB stick and a default dongle. Every time I inserted the dongle the notification goes "USB charging device" and changing to "transfer files" doesn't change anything. Playing a bit made a 32gb stick visible in a file manager (namely x-plore) and I was able to transfer files to it. But no PC recognizes the stick so far...
