PC Not detecting phone when connected to usb. - Samsung Galaxy A40 Questions & Answers

Hello! I wanted to transfer a 3gb img file with adb push from my pc to my phone because i do not have an sd card. After a few moments , i heard a disconnection sound from my pc , and it said that the usb malfunctioned and i should try connect it again. In adb it said "protocol failure". After connecting it again , it wouldn't get recognized anymore. What should i do? I dont have any os installed right now and no sd card. Is my usb cable or port broken?

Phone loses SD card

Why does my phone lose the SD memory card when i plug it in to my computer?
as soon as i plug in the usb cable, my phone loses what ever is on the SD card, and when i unplug it, the phone recognizes it again..any ideas?
thanks
When you connect the phone to your computer the computer allows you to use it as a disk drive in which you can drag and drop files onto your device. For some reason while this is happening you can not access it through your phone.
Next time you plug your phone in to your computer and a window comes up asking for activesync, diskdrive etc, press nothing (the screen goes away after 5 seconds) your phone will be completely normal and charging nicely from the computer
happy ending isnt it?

use the phone with activesync and not as a disk drive. .
You have your usb mode set as "disk drive" on the phone.
When it's so, when you connect USB the card is unmounted from the phone's OS so that the PC has direct access to it.
thanks,
where can i change that option? Is it possible to have the phone plugged in to a PC and watch a movie or music off the SD card?
Yes, if you choose activesync mode, as he said above. It normally asks you everytime you plug the USB calbe, but you most likely chose disk drive and checked the "don't ask again" checkbox. You can change it on settings tab, menu->more, connections, USB to PC.
ok, so my next question is, does activesync support windowsXP 64?
thats what we use here at work, and its giving me error messages when i try to use activesync.
What errors?
By default under Windows the software used to manage phones, which is called Activesync on XP, or WMDC on Vista/7, is not installed.
So if you plug the phone in ActiveSync mode on a PC that doesn't have it you'll see missing driver errors. If all you want is to charge the phone you can just ignore them, if you want to access the card/internal memory contents you need to download and install it.
My problem is, when i connect phone to PC with activesync and disconnect it, its working properly after this and i can use SDcard, but when connect it to pc like disc drive after disconnection off cable my phone dont see sdcard. This happening after ROM upgrade from 1.48 to 1.66. Can somone help

Usb problem

Hello! (first post , have been reading for a while though)
I can't connect the phone to my PC (win7 64bit), not as a mass storage device or with Kies (it worked fine before with my home PC and an XP machine at work).
It stopped working after the PC said "Device drivers installed properly" (or something like that) when I connected it, after that I have'nt been able to make it work as mass storage device on any computer..
Very strange and very annoying!
I'm thinking I might factory reset the phone (would very anti-nice though to loose all apps and stuff), so I thought I'd ask here first if there are any possible solutions..
Thx!
if you open device manager in Win7 x64 do you see it listed as GT-I9000 in Portable Devices ?
that's what it shows in mine, and i'm on x64 Win7
it automatically opens in Mass Storage also works in Kies
WEE!! Got it to work just now!!
Rebooted the phone (as I do every day) and connected it to charge over night, and windows popped up with the "installing device driver blabla dialogue" and suddenly it works!?!
This after not working for at least a week on any computer...
I have no idea what might have caused it, but I'm just happy it works again
Still, very strange...
It shows up in the device manager now, it did'nt before.. Thx for the reply!
On Win XP
is there a certain driver i have to download before using USB Mass Storage option.
all i get are two removable drives icon. but they can't be opened
you should only have 1 removeable device icon, 2 if you have a micro SD card inserted.
if you configure the phone to ask you what to do with the usb during connection, then you can select Kies or Mass Storage
regardless both works fine
i do have two removable drives because of the addition of the sd card
its set on Mass Storage. but it still won't open. im not sure if Windows installed it properly though
the driver details:
driver files- system32\drivers\USBSTOR.sys
does it shows in device manager, as mentioned above ?

After connecting the phone via USB, did tell the phone to Mount the drives?
anyone else encountered this issue?
Is anyone else having trouble connecting their Galaxy to a PC? I don't know whether mine is faulty or not. Downloaded the Samsung Kies software but when I plug in the Galaxy Windows is unable to find a MTP USB device driver and the phone refuses to connect. This happens Windows 7 Home Premium 64bit. Also the Galaxy has a complete fit and keeps flashing between the home screen and MTP application screen while it's connected (wxw.youtube.com/watch?v=R9hdpJPCP-k). And I don't get the usual Android option to mount for file transfer. Am I missing something?

finally managed to fix tis stupid kies connection problem...if anyone encountering the same issue jus do a factory restore n format ur internal sd card

Problem connecting to Defy's Memory card

Dear all,
I've been using Defy for 6 months, been alright, but for the last 2 wks, I have stopped being able to connect to my Defy's Memory card via USB cable anymore. I think perhaps I did uninstall some moto drivers or something, so I decided to reinstall it, but that wont help.
All it notify me on my Win 7 when I connect my defy is "Android ADB Device connected"
How am I supposed to solve this problem?
Thanks so much in advance,
You shouldn't need any drivers to connect to the memory card. When you plug the cable into the Defy, pull down the notification bar and select the USB Mass Storage option, then tap OK. (Also, go into your settings and make sure USB Debugging is not enabled.) The Defy will act like a USB thumb drive.
thanks a bunch, i forgot to turn it off, never thought bout that before.
i just updated to Wajkiui 1.12.16 today, n it just happened again. Can't connect to my sdcard even thou i turned usb debugging off already.
I tried going to recovery, and mount SD card through recovery menu, but nothing show up in my computer.
My external HDD can connect pretty well w the same usb port ... what on earth might be happening w my fone n pc?
I have same problem with Defy+
I have installed ICS.
In system menu I have "USB Debugging" OFF and if I select "Share SD Card",
USB debugging is still on and I cannot connect to SD card.

[Q] pc doenst see usb storage in rom or recovery ( code 10 error for WPH)

as the title suggest. my laptop does see the device as in it gives te connect sound and i can see the device in the devicemanager. but i cant acces the USB storage of my phone, not while in android or Recovery. only in magldr i can acces the usb storage with the masstorage option. i have a code 10 error in the devicemanager. and i have researched it a bit but i cant find a fix for it. i already tried to reinstall the drivers (plug-and-play install and manual driver instal) i cant get it to work.
does anyone have a solution?
kind regards.
what rom are you using.?
I have tried multiple roms Nand and Nativesd. all the same result. i think its either my phone or my laptop. but i dont know hoe to fix it.
first try all the usb ports on your computer...if not try deleting the drivers to find it and reinstall it again....try to see if another computer works fine or it gives you the same results...(also i should mention that for me only the original cable works...other cables works only for charging)
then i should try finding my old data cable. maybe that will fix it. with the cables i now have used my pc brings up that little usb thing icon in de statusbar in the right corner. but doenst see is when i open "my computer" . and in device manager it says error 10(device wont start) for WPH-filesystem
ok another thing...your sd card is fine.? if you insert your sd card to computer through card reader works fine.?
yep, even bought a new one yesterday. works if i put it in de cardreader. but not if the card is in the phone

[Q] "LG G2 " I really need help, I think I screwed up a lot.

I really need help, I think I screwed up a lot.
I've tried to flash a different ROM, but did not think that it was good.
So here is my big mistake, i have wiped it all away, also my backup, the only thing i can start up is TWRP v2.7.0.0.
I cant flash because i did not enable USB DEBUGGING before Wipe.
So i bought an OTG cable, but when i try to connect it, it wont mount..
Is there anything i can do, is there anyone that can help me.:crying:
My Phone is a LG G2 D802 without SD card slot..

Usb otg is for flash disks
take a flash disk (usb drive), format it @ FAT32
copy over your rom and flash it.
Or simply connect the device to the computer and push via
"adb push rom.zip /sdcard/rom.zip"
also usb debugging off/on is only for android (which is alive).
Feel free to ask.

Thanks for answer.
The problem is that when i connect a USB flash drive, it wont mount it.
And when i try to connect my phone to my PC through with ADB i cant see it, not even inside Device Manager, and i have installed ADB drivers many different ones in hope to make it work.
When i use my girlfriends phone that are the same model, then it works.
I have been reading that the PC can not see the Phone with out USB DEBUGGING activated.
But i do believe that with the right command inside TERMINAL of TWRP i can activate USB DEBUGGING.
try formatting into fat32 - the usb
