Computer doesn't recongnize mass storage and Kies cannot recognize phone either

Apparently, when I plug my phone in computer to put some files, pictures to phone, my computer doesn't recognize the phone's mass storage and neither do Kies
The message from the computer is : USB Device Not Recognized. One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message.
I thought there was something wrong with rom i installed, and tried unroot the phone, restored it to orignial rom. However, the problem is still there.
Please help me . Thank you for reading.

Did you use the USB cable that came with the phone? I noticed mine doesn't come up on the pc unless I use the cable that came with it, otherwise with any other cable is just charges and nothing more.

I would suggest buying a new cable and trying that. Seems a lot of users are encountering this lately. The wires that carry data fail, but the wires that carry power still function. It doesn't have to be a Samsung branded cable, but one specifically for charging/data for the SGH-T989. It happened to me both on this phone, and my Transformer. Both times it was solved by using a new cable.
Your local electronics store should carry what you need. Good luck!

I tried it. No help :/. I think it is the phone's usb port that makes this problem. Probably I'll send it to samsung company to have it fixed.

Before u diagnose the phone as the issue i would check and try plugging it to another pc besides the one that doesnt detect it because i have the same issue with my main pc. When i plug it it opens up as an unreadable drive, it wount open or anything, but when i plug it to my laptop it works perfect.
kind of wierd but it works. i also tried installing kies and didnt help at all. now it it still doesnt work than yea probably the phone.

Yah, it's probably the phone. I tried plug it in my brother's laptop and computer (Kies installed) and still nothing happens.

Allgamer had a similar problem. Turns out it was his cable

Try the free wifi explorer from the marketplace.

Also remove sim, sd card, and battery for a bit then replace. Also, get the most "official" cable you can. I'm working with an old evo cable and an old g2 cable. Some of the car charging ones/generics won't play nice. Try blowing (light laughing allowed) into the port.

Finally!!
Ok here is what i did:
1-enable EHCI on your computer from device manage >> http://www.intel.com/technology/usb/ehcispec.htm
2-took a portable toothbrush with isoprop (swabbing alcohol)
3-took my phone to the gas station ...25c air and dried the crap out of it
4-wipe/reset my phone from fast boot menu (not android menu)
5-got an LG "B" data cable...
voila monsieur !!!! i dont know which was the silverbullet but i aint complainin.
However, it was still nice to know that Samsung is a no questions asked manufacturer.
Someone was having the same issues as mine in russia, and he said ICS 4.0 did it and is waaaaaaaaaaay better for this phone. Im gonna give this to a friend and WILL NOT touch these till ICS 4 officially comes out here. Tooo much hassle and ive got too much info riding on it (phone). <<personal opinion

[Q] Did I finally brick it?

I was installing a new Kernel late last night, kernel didn't have a posted checksum and yet I flashed anyway. CWM said it had flashed correctly. I erased my cache and dalvik and rebooted. Now I can't make it past the SAMSUNG screen. Cool! I'm no noob (just a lurker), I've run into problems before. It won't go into CWM, acts like it really wants too, but goes back to the SAMSUNG screen when it should be displaying CWM. I go to ODIN back to stock, put the phone into 'download mode' and the computer can't find the phone. I tried 3 different cords, all of my USB ports, battery pull and put back into 'download mode', reinstalled the Samsung drivers - nothing. I've used Heimdall several times in the past on my Ubuntu laptop. I try using Heimdall, all the USB ports, cords, Heimdall can't see the phone in download mode. I've run out of ideas, where do I go from here? Should I start looking for a replacement phone?

Hm
Try another computer? I've been having tough times with my Epic too, but i think its because I've worn down the pins on the Epic's side..
I totally see myself buying a brand new epic, and transferring my old epic's life into the new one, just to make sure I wont ever be able to not recover my phone.

Could be gunk in the usb port. This allows the charge but not necessarily the data connection. See if you can clean it.

Just use a different computer. You'd be surprised how some comps just won't work but another will using the same exact files, USB cable, etc.

I've tried two computers thus far. I think I'm going to try cleaning the port... somehow...

Slide in the USB slow on both the PC and the phone.

I know you said your not a noob just a lurker but sometimes the simplest things elude us. Did you pull battery and memory card and then try to go into d/l mode?

I've Scoured and Searched need help

Ok here goes the best to say i just got an epic 4g and i really really wanna keep this phone. First things first I installed the update to the phone for FC 09 i feel kinda dumb now for doing that. The phone now just constantly reboots when the screen comes on after it being off. As well usb is not recognized ive tried everything new cables other cables other computers other drivers official drivers. I would like to some how get off the fc 09 update but theirs no way for odin or even hemidell to recognize my device. Can anyone please help me out

Well, it's worth trying make sure to cover all your bases again to get Odin to work. It shouldn't be that difficult to get it to work. I have no problem, even with stock cables. Worst case scenario, you're bone stock, so you may be able to get Sprint to take care of the issue for you.

without the usb connecting is their any way for odin to connect I've used every possible driver for the phone and others from devices similar is their other drivers then just the usb driver i use to have a lg optimas s and i needed like 3 drivers to ever get that thing connected

Try uninstalling all device drivers you don't need for other devices and the epic. Reboot, do a reinstall, and reboot again. Try connecting again, and give it some time. If drivers aren't installing still after a few minutes, unplug and plug in again. Give it a min or two to finish installing the drivers. Open Odin and try one more time. If it lists a com port in yellow, you've done it. Otherwise I'm unsure why it's not connecting. Also, try the different cables if drivers aren't installing. And use different USB Ports on your computer if issues persist.

What OS are you attempting to use. Vista and 7 were picky for me the try to use the phone initially as a mass storage device. Is it trying to connect and failing to associate the drivers or just nothing at all? Sometimes a battery pull and mashing buttons for 20 seconds then plugging in with odin open, with no battery helps.

My main computer is windows xp pro service pack 3 ive installed the particalur drivers it charges through usb but that is all. still havnt figured it out my other computer is windows 7 ultimate and it doesnt recognize it there either ive also tried loading it through a hub with no go but ill try some of the things you guys said again and make shure to follow them to the key

You should only need the Samsung drivers to get it to connect. I always use a USB port on the back of the tower instead of a front port. Sometimes they can be flaky. Good luck.

probably going to take it back to sprint next week i bought off of someone else becuase i wanted a new phone. I'll pay the 35 to get it replaced thanks for all those who have helped me out its greatly appreciated

Yepper. But that is a good point too, I cannot get my epic or epic touch to connect without plugging into a USB port integrated into the motherboard. Even then I sometimes have to plug and unplug a couple quick times. Mine are still picky too.

I had to go to samsung website and download the drivers for the epic from there. Also try different usb ports. A good thick blackberry cable has never failed me.

No USB connection to computer - Not the usual driver issue

Hey all,
I picked up a used Nexus (VZW version) about a month ago and have been struggling with this issue. No matter what I've tried, I cannot get the phone to connect to any type of PC in MTP or PTP mode. I have been able to get it to connect in Fastboot mode on a PC, but that's about it.
I've tried NUMEROUS fixes after scouring the net for the past three weeks. I've tried on a Mac using Android Transfer, on an XP and Windows 7 PC using various drivers and toolkits, even the SDK, but nothing seems to work. I've used official Samsung drivers, naked drivers, wug's toolkit, another Nexus toolkit, pdanet, but none produced a different result. At one point I noticed that the pins on the USB terminal were bent and even went as far as replacing the USB port. I used factory Samsung cables and any other that I could get my hands on, but still no luck. It seems that the phone is not sending any type of signal for the computer to respond to. I get nothing popping up in Device Manager, not even an "unknown device" warning from Windows.
At this point I have to assume there is some sort of software issue (phone side) that is preventing the connection, but I don't know what. I thought I had a lead last week with changing something using the PhoneUtil settings, but I can't seem to find the right *, #, number combo to get into the settings.
Any ideas would be appreciated...I'm really not sure what my next step is.
Thanks in advance.

If fastboot devices lists your device when booted into the bootloader, I doubt this is a HW issue. Since you already tried so much, I can only write what I would do in your case:
1) get a clean install of Windows (XP or 7, doesn't matter). No restore point stuff, format C:\ and reinstall using the DVD.
2) do NOT install any drivers yet
3) open device manager
4) connect your GNEX and watch for changes
If you do see an unknown device now, update its driver using the naked driver.

Thanks for the suggestion. I'm gonna give that a shot in the morning and I'll report back.
The only other possibility that I could come up with was firmware. But I'm guessing that it since I tried stock 4.0.4 and 4.1.1 that it rules that out.

Ok, so after a clean install of XP, including formatting the drive, I still get no response in the Device Manager when I plug in my phone.

Unexpected. Does your phone react when you connect it to the PC (starts charging, mentions 'connected as a media device')?

Yeah, I know. I'm baffled. No, doesn't show that it is charging, unless I turn it off completely. And no, doesn't say anything about being connected to the computer.

It could be worth a try to inspect your USB port. Use a flashlight to see if something is bent or damaged inside.

If you are talking about the one on the phone, I replaced it about 2 weeks ago with a brand new one.

Oh yeah right, I didn't re-read your OP. Looks like I'm out of ideas for this one, sorry.

Have you tried switching to a higher priority USB port? There should be a few on the back of your tower (assuming its a tower).

No problem. Thanks for the ideas though. At least I'm somewhat narrowing it down. In the meantime, I picked up an OTG cable so I can load media files, and that seems to be working well.

Help w/ Replacement Note 4 says unknown device in Windows. Old works fine

I have tried uninstalling and reinstalling drivers.
I have installed kids and then smart switch.
My old note 4 that was defective shows up in Windows but the replacement shows as 'unknown device'
I tried safe mode to un install drivers and different USB ports.
Is my device defective? Any ideas?
Thanks!

Maybe try going to developer options and checking if usb debugging is turned off. Try turning it on. Try a different usb port. Try to switch between different usb modes in the notification area when connected. Last but not least factory reset your phone in recovery mode and try connecting it after.

I am experiencing the same problem but I have another problem as well. My phone is an unrooted Galaxy Note 4 running 5.0.1 w/ VRU2BOG5 build. I have tried just about all the USB ports on my computer and get the same result, "unknown device". I have uninstall and reinstalled kies and the associated drivers and still get the same result. I have factory reset the phone and still the same. I was even able to do a firmware upgrade and initialization via kies and still the same problem.
The other problem I am faced with is I can not seem to get any OTG cable to work on my device. Could this be hand in hand?
I am not sure if you (the OP) have noticed but when you installed kies, have you gotten an error for your ethernet controller under other devices in your device manager?
I really like the phone but if I can't 1) root it or 2) transfer data via the usb port (especially through the OTG cable), the phone is useless to me. Any help would be very appreciated.

The USB port may be defective. I replaced mine on my note 2 myself for cheap. But if the phone is still under warranty let them deal with it. You guys tried different cables/computers?

I am not entirely sure it's a bad port but could be. On my note, everything besides a flash drive via OTG cable works. Oh and the computer but it will connect to my laptop. I dunno I'm about to sell the phone.
