[Q] Impossible to connect USB - ''Not of USB charging. Dont launch MTP APP''

New phone, it's not an I9000, it's a Samsung Galaxy 3 (I5800), if this is the wrong forum, my apologies.
First days everything went fine, even with Kies in 2 PCs.
Things start going really wrong this morning when I connected the phone to the laptop, mass storage option selected, dragged notifier, unmount sdcard option was available.
Checked the laptop and I had no sdcard drive in explorer.
Updated Kies, tried the usb drivers available in this forum, nothing worked.
Backup of sdcard through an sdcard reader, format sdcard, and the end result is the same. Meanwhile during the morning, the notifier disappeared, I had no option to unmount the sdcard anymore. When I connect the usb cable to the pc, pc says "Hi", phone says "Bye" (both do a sound) and nothing happens.
Resuming, phone is rooted, XP on the laptop, Win7 on the PC, updated Kies, updated drivers, tried USB Debugging, keep-alive option, all usb options available beside mass-storage, changed back to TWLauncher, same result: Nothing.
When connecting the phone to a different usb port, windows installs 2 modem drivers and a Samsung USB Composite Device.
Part of the logfiles say:
E/MTPRx ( 9735): In MtpReceiverandroid.intent.action.ACTION_POWER_CONNECTED
E/MTPRX ( 9735): Battery charging. plugType = 1
E/MTPRx ( 9735): Not of USB charging. Dont lauch MTP APP
E/Setting ( 9810): Intent Action android.intent.action.ACTION_POWER_CONNECTED
E/Setting ( 9810): Battery charging. plugType = 1
E/Setting ( 9810): AC charge
I'm sending the log in attach in case someone wants to have a look.
And now the questions:
- I still have 2 more days to replace the phone for a new one, do you think this is an hardware problem? Usb Cable?
- I will not be able to upgrade the firmware without a working usb connection correct ? Or is it possible to put the firmware file on the sdcard and upgrade it from there?
Thanks for the help.

Update:
- It's not the cable, I just tried to connect it with another cable I had around here (from my old Nokia xpress)

This is stupid... solved it with a hard reset/factory defaults + sdcard format :-/

PC not detecting Tablet.

[Edit, first post and I got the board wrong. -_-. I thought I was in the troubleshooting section, sorry.]
Hello,
I've bought a used Galaxy Samsung GT-P1000 running Froyo.JPJM5, Firmware 2.2, and Kernal 2.6.32.9, 27.7GB internal memory.
My problem is that I can't get the PC to identify the tablet using the USB cable.
What I do and what happens when I plug in the tablet~
(USB Debugging on)
I connect the USB cable into the PC first. I plug the cable into the tablet. A 'USB is connected' notification shows up. I open it, and click mount.
I look at my computer's monitor and there's absolutely nothing showing that it EITHER identified or not! It doesn't even show a popup.
So I went to my Disk Management to check if it was hidden or something. There's nothing. It just shows my regular hard disks and that's it. No mounted anything. I even looked into my Device Manager and all seems working.
(USB Debugging off)
Nothing happens in either the PC or Tablet.
Things I've tried-
1) Enable USB Debugging.
- Plugging in the tablet, restart computer, and then enable USB Debugging while connected.
- Disable USB Debugging, restart computer w/ tablet connected.
- Plug tablet into PC, and then restart tablet. (with USB debugging and not)
2) Get KIES.
3) Uninstall KIES and only download the USB_drivers.exe thing that comes with KIES.
4) Uninstall everything (including drivers) and getting Android SDK + update everything (about 370mb).
5) Install Ubuntu and trying to get it identified + downloaded Android SDK package and updated everything. (also did lsusb- it doesn't see the tablet)
6) Tried each and every USB port in my PC. (10 ports). [Note: My other Android phone works in any of them)
7) Tried my bro's and sis' comp (win7 32bit)
8) Tried my dad's laptop (win7 64bit)
9) I unplugged tablet, placed the memory card(2GB) of my Android phone into it. Plugged it in my computer and yet it doesn't want to see it.
10) I went to a shop because I thought the USB cable is broken or the port hub is broken. The guy took it and plugged it on his PC using my own cable. He identified the problem and said "It needs its software to be updated". I asked how much, and he said $15. **** that ****. If he can do it, I can do it.
Conclusions up until now:
Tablet knows that its getting hooked up by the computer yet it doesn't send any information to the PC letting it know that it's a mounted drive.
USB Cable is fine.
Port hub is fine since it can detect the USB cable on *usb debugging* mode and I can charge the tablet with the USB cable plugged into the charger.
---------------------------------------------
Note: I tried to root it using z4root which doesn't require a USB connection. It doesn't work. It would work and work until the application crashes and I can't re open it as it always crashes after the first try. I tried using the temporary root option and it would load forever. All in all, doesn't work.
Note2: I attached 2 screenshots. One for my Disk Management window showing my partitions while the tablet is connected (and I pressed Mount on tablet). Second, is for my Device Manager window showing that there no unidentified devices and that the USB devices don't show any Android connected, yet on tablet it says it's mounted.
Thanks.

I don't know too much about how to fix windows.
But when you are using ubuntu,
did you put in this line to your /etc/udev/rules.d/51-android.rules
SUBSYSTEM=="usb", SYSFS{idVendor}=="04e8", MODE="0666"
btw, the 51-blabla filename can be 51-xxxxxanything
once done
sudo /etc/init.d/udev restart
plug in your tab to USB port
then if you have your Android SDK, you should have adb?
do
adb devices
does it show your tab?

I did what you just said. There's nothing. :|

Hmm..
Out of idea.

If it isn't recognizing the sd card you could try another one. Format it in the tablet, plug it into the computer, put the update on the sd card and update that way and see if it gets recognized that way.

What do you mean by 'put the update on the sd card'. What update?
Anyways, what I tried is that I used another SD Card (128MB), placed it in, formatted it in the tablet, and plugged it into the computer. Nothing happened on the PC. :|
'adb devices' doesn't show any devices connected either.
(I wanted to confirm that 'adb devices' is indeed working so I tried plugging my Android phone (ST-GT602) and ran adb devices- it showed it. But not the tablet.)
Is there anything other than z4root to root a phone without a USB connection? Or is there anything that might trigger the tablet to let the PC identify it? For example, is there anything that I can place on the SD Card (through another connection.. using my phone for example), then plug it into the tablet, then run that application?
I don't care if it's for rooting or not. Perhaps it would help.

Why don't you spend that $15 at the shop?
Very curious why it works for him.

You might find the Android update online (ICS to GB) or something like that and try to flash a signed update but if your computer doesn't recognize an Android formatted sd card I'm not sure how you would get the card formatted and then get the information to the card. You might search for the update on your tablet, download it and flash it using stock recovery. Maybe getting it updated might work but I have no idea why an out of date tablet won't show up
Also you could try searching online for modified drivers for the device.
Par that I have no idea. Might have to go back and pay the 15 but I would ask the repair guy if you could watch step by step what he is doing.
Hope the best for you.

Can't Use USB File Transfer - Android Driver indicates failure

Hi - For a long time, my OP3T worked fine when I would connect the USB to do file transfers.
However, for a few weeks now, USB File Transfer stopped working. on my home PC. I know that there must be some issue with my PC because USB File Transfer works fine with my Win10 work PC.
PTP transfer seems to work OK on the Home PC. When I look at the Other Devices >> Android in Win10 Device Manager, there is a exclamation point indicating a driver failure. I have tried installing/reinstalling the official OnePlus USB drivers, but no luck.
Can anyone help?
Thanks,
¿GJ?

Hi ! I post again because when I connect usb key mtp works and if I connect to my mac and go to settings usb parameters and choose transfert files/Android auto that work but never had notification pop-up for choose it

USB is a master/slave protocol. When you plug in an otg cable, your phone's USB controller switches into host mode. Your computer's USB is always in host mode. So your effectively trying to get two master devices to communicate which USB does not support.

Question File transfer to PC

Impossible for me now to transfer files from PC to P7. Whenever the content loads, the explorer windows shuts down. Very annoying.
Any fix ?

I had to use usb 3.0 port because 2.0 was giving me the exact same problem as you're facing.
Alternatively you can copy the files you want onto a usb stick and then connect it to your phone using the provided usb c adapter. I've done it few times and it works well.

Worked, thank you. Very strange.

Can you totally deny it is frozen because the transfer is taking time (ongoing) ?
I could imagine that it just waits for the task to be finished before accepting further commands.

I had this happen as well, I would select the MTP mode (file transfer/android auto or something) and it would disconnect from the computer. Switching to another USB-C cable fixed the issue
