[Q] Why can't i connect using the usb?

Well guys i have a big problem. Its shouldn't be that big considering its a connection problem, but i can't seem to be able to fix it. I've been trying to connect to my laptop/desktop using the supplied micro usb and a blackberry micro usb, but it won't let me transfer files. the option to turn on storage doesn't even pop up on the notifications. it charges but thats it. i have all necessary drivers and the USB debugging option is checked. Any info or help would be welcome thanks!!

What O/S are you using?

I had the same problem. No one gave me a problem solving answer

USB Debugging should be unchecked and Mass Storage is Checked.
Settings > Phone Storage > Mass Storage only = Checked.
hope this helps.

I've tried that before w no success :-( thanks though

Mine wouldn't connect until i reinstalled the LG T-Mobile G2x drivers and now it mounts every time. The drivers in the updater tool installed the 3.2.1 drivers which is for the G-slate. You need the 2.2 drivers which are for the G2x, if you need them just pm me and i can send them to you.

i deleted and reinstalled the 2.2 drivers with no success. im starting to think there's something wrong with my phone. But it could also be that i'm now running the Gingerbread leak from yesterday. rooted and working perfectly... well almost. i just need to get usb connection working.

Similar issue. This worked for me on Win 7.
Uninstall the LG Drivers and reinstall the G2x 2.2 package from LG.COM /us/support/mc-support/mobile-phone-support.jsp (I can't post links)
Plug the phone in and go to Device Manager. There should be a USB Composite Device that is not properly installed. Right click it and select Update Driver Software.
Select 'Browse my computer', then 'Let me pick'. Choose have disk, and browse to where the LG Drivers are installed. Likely C:\Program Files\LG Electronics\LG United Mobile Driver\ and select lgbus9x.inf.
Then pick LGE Android Platform Composite USB Device from the list of drivers. Should be the top option. Hit next.
I let it sit for a minute while the drivers installed. Some things registered in device manager right away, the LGE USB Modem for one. But, the drives didn't. Unplugged the phone, plugged it back in, and the drives popped up under Portable Devices.

@conspirator_boff i tried ur steps, but i couldn't find the USB Composite Device in the list of the USB Controllers in Device manager. Am i missing a step?

Humm, depending how it is connected it could have a different name. Do you have anything that isn't installed properly?
Also, if you haven't, you might want to look into mother board / system driver updates.

I'm in exactly the same boat. Running on Win 7 64 bit.. tried both 2.3 and 2.2 drivers but no luck. It doesn't get detected AT ALL. Tried with 3 different USB Cable on 3 different ports. I can connect other phones to the same port/cable without any issues.
I suspect there is actually something wrong with the phone or with a specific batch of phones. I googled around and read about a couple (husband and wife) who connected both their G2x's to the same computer on the same port/cable 1 at a time. One always worked, and the other never worked. I believe he eventually returned it and got a new one which worked fine.
We may have ended up with the ones from a bad batch?

I believe so... but why did it happen until now? I've had it since 2 weeks after launch, and this was the first time it happened. I guess ill call CS to get a replacement.

Hmm interesting. I can't say the same for mine since this was the very first time I actually connected it up to the computer. Mine is completely stock and I bought it at launch.

Just to give you guys an update:
I took my G2x to a local T-Mobile store. They tested my phone out on their own computers and it did not mount via USB. They ordered a replacement phone so it is actually an issue for some people and not drivers/system setup. Apparently I was the 3rd case that the store had encountered.

Mine wouldn't connect until i turned USB debugging on, now it connects every time. Might give that a try.

[Q] USB not connecting to PC

After unrooting my phone to take to Verizon for some repairs, I can't connect my phone to a computer. I haven't connected my phone to a computer since I rooted back in March. And you don't need to connect to unroot.
I read somewhere that upgrading the radio will fix it but I'm not rooted so I can't. All I want to do is root again and I cannot. My mac doesn't see with osx or bootcamp, it and neither does my Windows 7 desktop. It's not that it's unrecognized, my computers just can't find it.
Is there some fix that I'm just not finding? Or is my USB port fried? I've tried another cable as well.
I can still charge so idk. I'm at a loss.

I had something similar happen to me the other day. I upgraded the hard drive on my netbook & then did a fresh install of Windows 7 Ultimate x64. upon getting it up & running, I plugged in my phone and it just said "USB device not recognized".
Seeing as how I ocassionally do wired tethering with PDAnet, I loaded PDAnet on to the netbook & then it specified to disconnect my phone & asked what manufacturer phone I have. I selected "HTC", it installed HTC drivers, then asked me to plugmy phone back in(with USB debugging on), then it said it was installing my phone and everything went smooth from there.

Right, but I don't even get "Unknown Device" or "Device not recognized". Absolutely nothing happens.
My phone will charge but neither device talks to each other.

you ate sure igs a USB 2.0/3.0 and not a 1.0 jack?
czn you trhy on someone elses pc?
normally wjen a USB jack goes out that's it.
sprryfor typos, lpud music and alcohol. id say what else but domt want some law enforcement type to see my post. weee

that *might* work.. if your PC is a store bought system, you'd just go to the manufacturers website and download the drivers from the 'downloads/support' page, then uninstall from device manager, reboot, re-install(and possibly reboot again).
if it's a custom PC, you'd goto the motherboard manufacturers page & do the same thing. if you don't know the make/model of the motherboard, it will also tell you in device manager(or just remove the side of the case and look at the motherboard itself, it'll be labelled somewhere near the cpu).

If by loading Hboot you mean loading the bootloader and trying every single option (even Hboot USB), then yes.

I can't even get the computers to recognize that I need a driver or that I have a device connected.

not sure if you've tried another USB cable or not, but if you have and it's still doing the same thing then it has to be a hardware related issue. possibly something wrong with the USB connection on your phone.
Awhile back, mine was doing something weird where when i'd plug it in to charge it and it kept showing that it was constantly charging, then not charging... I thought "what the hell!?".. I ended up trying canned air and it helped a little.. but started up again. I finally used some 'electrical parts cleaner' on it and ever since it's been functioning normally again.

not sure if you've tried another USB cable or not

it helps to read the entire post apparently ;P
well, in the time I've had my TBolt, I've tried out every radio & countless rom/kernal variations. I have never had an issue connecting to PC on any radio so I doubt the radio has anything to do with your issue.
You have already attempted everything else though(a side from the cleaning) so i'd wonder if there's some sort of issue with the software on your phone.

I have had this exact problem.. have tried different PC's, different cords, different usb ports...I have tried to mount under CWM also. Computers don't give any indication that there is anything hooked into them....the phone does charge however. I have reinstalled the ROM (using CM7.1.1) I have intalled previous backups which had no problems linking to my PC. I have not tried to clean the charging port..will give that a go...I feel I will have to by a card reader for my pc to read the microSD. worked fine for 6 months, but then just quit. Posted this problem on android central...but no one could figure out a solution, thought someone here might have....last post on my AC thread from someone with same problem was told by verizon/htc to send it back for replacement...don't want to but might have to do this...love to have a brilliant idea before I do though! Can't post the link to the AC thread as I am a new registered user here..been trolling all year...but you can find it under the Thunderbolt Rooting. ROM's and Hacks area.....

I'm pretty sure no one has a solution to our problem. I've taken compressed air and cleaned everything and still no luck. It's just a question of how much they'll charge me for it.

Problem!

My original Sensation broke due to the USB port and it not being able to charge.
I have my replacement, I'm rooted and everything, now a new problem arises.
When connected to computer, I don't get a prompt nor does it recognize that it is connected to a computer; however, it does charge. I have no option to mount as disk drive, etc.
What's the problem?
This happened before I flashed a new Rom, but I managed to flash ARHD 6.2.1 through other means. I thought it would fix it, but nothing.
EDIT: Could it be the computer? I will try on my coworkers computer, although it was working on mine before this process.

I think it is just a hardware fault again, but you can check usb debugging, check if you have any setting as default by fault. wich will end the notfy.

I tried it on a coworkers computer, and it detected that a computer was connected. I'm not sure what happened on mine, but no such detection after rooting and etc.

Re download and install the drivers.

something similar to this happened to my Sensation just out of the blue. I tried different cables but nothing worked, it would just charge but not mount. I eventually figured out it was my laptop and simply rebooted it and everything worked just fine, hope this works for you!

It's all good now. At first I thought it was a problem with the Senny.
However, I ran device manager on the computer, and then re-booted. All is well now. Thanks.

[Q] USB connection

My Infuse 4G AT&T
I have this Issue where i or if i need go go back to stock for any reason, I can't.
USB pluged in; all its doing is charge, no data transfer no nothing, i have re-installed Kies and infuse drivers,; nothing same ordeal. I went to Download Mode, and obviously USB wont recognize. So i cant use Odin either for these reasons.

Is there any one out there may have a solution, or a modification ?
Thanks in Advanced!

Sounds like you are using a "charge only" USB cord. Do you have the one that came in the box with your Infuse?

USB not working
When I try to connect to the computer to transfer music or whatever to the Infuse it won't let me. I plug in the data cable click mass storage, click connect USB I get "do you want to scan and fix". If I click scan and fix I get "check disk options". Any combination of the check boxes will make the phone disappear and starts the scanning process, like I had disconnected it. I'm running Zeus 6 w/ICS theme for build 6. Is there any special way these disks should be formatted? Any help would be appreciated.

Wow! Nothing?
Now when I plug in to the computer it doesn't even recognize the phone. It's like I never plugged it in. The phone will still asks kies/media/mass storage. I click mass storage then click connect to PC then nothing. It's almost to the point of going out on the deck and teach this phone how to fly.

my infuse is doing about the same thing.
plug it into the wall...nothing.
try different outlet...nothing.
try different charger and cord...nothing.
plug it into my computer...starts to charge only, no usb mode.
computer says "one of the usb devices attached to this computer has malfunctioned, and windows does not recognize it.
ANY HELP?

I had the something happen yesterday. I restarted phone and pc but same thing. Ended up cleaning the mini usb port on the phone with an old toothbrush (and nothing else) and it started working again! Must have been some crap in there or something.

[Q] PC Won't recognize my phone

Hello again! So I recently picked up a Galaxy S 4g for a good deal, and now for some reason, I can't connect it to my pc. I plug it in via usb, I've tried all the USB settings, and my pc won't recognize it at all. I've searched everywhere on the web, and on these forums, and still no dice. I found another similar thread from about a year ago, and nobody really gave a concrete answer there. I've tried in debug mode also. The phone charges when it is plugged in, but that is all. I installed the Kies Mini and the drivers on my work pc (Win7 x64) and it still won't recognize my phone. At home I'm running Win8 x64, and Kies Mini won't even download the drivers, it just sticks at 0%. If anyone has any ideas as to why it won't work, or options that I can try, it would be greatly appreciated. Also, it is not rooted. The point of this is to try to root it. I've rooted many other Android phones without issue. This one's being a tricky little bugger!
Thanks in advance.

You will need to install the drivers for your phone on the pc. Also check out your usb cable some give me problems

Had a similar problem on my win7 laptop. Decided to start over on my winXP pc and Kies mini worked to install drivers.

Well I've tried multiple USB cables, and both of the ones I have work with my Windows phone so im pretty sure those aren't the issue.
I will set up a PC with XP today then and see what happens. Will post with results. Thanks in advance!

I'm using windows 7 with no issues

I got it to work! Here's how:
I tried installing XP on a pc that I was setting up for my grandma, and still had the same problem. Having been working on this for a few days, I got frusturated, and brought it to my Dad to have him give it a go (he's done tons of rooting/unlocking on tons of phones, and he is in the 360 modding scene) and lo and behold, he got it. It was just the USB cables I was using I guess. He hooked it up with the cable from his Kindle Fire, and it worked instantly. Looks like I just need to pick up a new cable, because all 3 of mine are ****ty >.>
Thanks for the help guys!

Make sure MTP is checked under storage -> press menu -> USB Computer connection
EDIT: sorry i didnt see you had it solved
