USB Not Recognized

Previously my USB port was working fine and mass storage was working correctly. Now I can't connect to my laptop and it says USB Device Not Recognized. I wiped out my laptop and it still doesn't work. I've looked around and nothing seems to solve my problem. I'm on SyndicateROM Frozen 1.0.2 and running Windows 7 32-bit. Can anyone solve my problem?

Are you using the stock samsung cable? If so ditch it for anything else. Their stock cable flakes out...
Sent from my ACS frozen Epic

I'm using the stock cable. where would you recommend to get another one?

i have been dealing with this problem for about a week and a half. I never thought it was the USB. I borrowed my brothers blackberry usb cable and it worked like a charm. Thanks.

I have tons laying around from various other devices, any Micro USB should do. If you don't have any from other devices then any place like radio shack, office max/depot, staples, microcenter, bestbuy.... should carry them, probably even walmart and target in the electronics section. You are looking for a micro USB cable.
You don't need anything fancy(expensive) that's gold plated, high speed, etc... Just try to find something that looks a little less flimsy than the one Samsung gave us.

1. Buy this
2. Plug phone into PC
3. ?????
4. CEELLLEEEBRATE GOOD TIMES COME ON!

Just use a different cable. The cable that comes with the phone is a pos.... How i know?? My girlfriend almost threw the phone and the laptop over the window.. when she got tired of being trying she asked me and I just got the cable from my Evo and voila!!! Its working!!!

Also I had issues if it was a case USB and not one directly on the mobo.

I just used my sisters cable and now it works like a charm.

can't connect to usb

i can't connect my sgs2 to USB storage. when i plug in the usb cable to my computer and phone it will charge but nothing else happen. i had stock rom before but are currently using jug 4.0. i thought it was the rom so i downgraded to 3.69. still the same problem. i mean i can do anything with the phone just can't let my computer detect the phone. i tried to reinstall the driver, nothing works. please help!

Is your cable a samsung branded one? I had that same problem but with stock rom. I used an LG branded cable and the phone would connect to the computer and charge, but would not go into USB mode.

yeah, i am using the one that came with the phone, i guess i will try to use a different one. it was working fine before, don't know why it just stopped!

This has happened a few time for me. Sometimes the phone has only needed a reboot, the wire definitely plays a big role... I bought some cheap cables that didn't work at all... some of the older roms wouldn't show USB connected unless drivers were installed (kies). An issue I've more recently unveiled is after using an MHL adapter sometimes the USB will connect for 30-60 seconds before unmounting storage again. Hope that helps
My SGSII HercuDom needs more w00t. It always needs more w00t!

I had the same problem on a stock phone (purchased in late Oct from T-Mobile store in Arizona). I would connect it to the computer and it would charge but would not recognize the USB function (for data transfer or modem use).
Took it back to T-Mobile and they overnighted me a new one for no charge. New one works fine.

USB cable "OTG" not working am I doing it wrong?

I got a Micro-USB to USB (female) cable form ebay... from China (I didn't know until I chekced later. I usually have the "UK sellers only" option checked).
Anyway, after an eternity, it arrived today. But, it doesn't work when I plug it in. Nothing happens. My Sandisk Cruzer doesn't light up when I plug it in or anything.
I was on the ninphetamin3 Kernel, and I've tried the Siyah kernel, just in case it's the kernel that was limiting functionality... Apparently it's not because it still doesn't work.
It only cost a couple of quid, but is there something I might be missing that I can check before buying another from the UK?

That is not necessarily an OTG cable... did it SAY it was an OTG cable? If not, it probably isnt. Pin 4 and 5 need to be connected (in the micro usb side) for it trigger OTG functionality. if it is not working it means one of 2 things:
1. You didn't buy and OTG cable, you just bought a cable with the ends you wanted, but without the funtionality
2. Something is broken on your phone... test that cable in another phone with OTG capability (go to a verizon store if you have to)
3. I think i remember seeing you need an app to use some flash drives (keybaords and mice work without any app, i can attest to that from experience)

That's the one I got. It's 5pin, but you're right in that it doesn't say it was OTG.
I don't have another OTG compatible device to test with

I got an OTG cable and I tired loads of different things to get it working.... in the end I rebooted the S3 with a usb drive connected and it worked after that.
I'm on stock rooted LG6
This is what I got

yep, it is just a plug adapter.
You now have 2 choices:
1. cut open the micro USB, and connect pins 5 and six
2. buy one that actually says it is an OTG

I ordered a OTG cable now, but also soldered the one I had and made that into one too., But the OTG one will be ok to pull out in public places, lol.

USB to PC - PC not recognizing device?

Alright, so when plugging my phone into my new (literally bought today) netbook, nothing happens.
I installed the Samsung USB drivers as well as Kies. And when plugging the phone in afterwards, nothing happens. From my understanding, whenever plugging in a device into the PC, a bubble on the bottom right hand side would pop up saying "Installing device hardware" or something along those lines.
But for this netbook, nothing. Nothing pops up at all. It's like it doesn't even know a device is plugged in. Although, my phone does charge from the connection and that's about it.
I've used 4 different cables. Two generic cables, Energizer cable, and a RocketFish cable. I was successful with the Energizer cable when I used my friend's laptop to ODIN back to EL29 from the FH13 update.
I'm pretty much stumped right now. Not sure what's going on. Considering returning the laptop and exchanging it for another one.

Have you tried turning on USB debugging?
Sent from my SPH-D710 using xda app-developers app

Yes I have.
The netbook will recognize my flash drive though. But not the phone. :|

Welp, went back and returned for Asus laptop. The thing recognized everything. I guess the netbook wasn't meant to be.

Go into your dialer and type ##8778# switch to cp and youll see that your device will start downloading the drivers then you should be in business sorry if I put cp wrong long day but I think thats it there should be 3 settings there the one your on cp and all I think so once your done make sure you go back in and change back afterwards or your sd card wont read right. Hope this helps if so say thanks

There is a known issue where the USB port "breaks" somehow. I just experienced this, so it may be your issue also.
Troubleshoot:
drivers
different cords
different devices
Which you have done so it's most likely your phones USB port

RK3188 1024x600 front USB not working? Any workarounds?

I'm not able to get to the bootloader screen because the front usb port is not functioning on my unit. Has anyone been able to use one of the USB ports on the back to get to ADB and/or get to the bootloader? Is this a known issue with a workaround? I've done quite a bit of searching and have not turned up any solutions. Considering what is involved in shipping this back, I'd much rather figure something out. Thanks in advance for any help!
Edit: I should mention that I have used the adbon password and it does acknowledge that adb has been enabled. Just nothing seems to work on the front port. When I connect my Linux machine and run lsusb nothing shows for the unit. I have considered buying or making a USB-A to USB-A cable to connect my computer to one of the back USB ports, but I'm concerned about how these back USB ports are designed. Is it as simple as a built-in OTG cable? If so I'm probably fine. If it is more like a computer's USB port I could damage my laptop, my headunit, or both. I'd really like to hear if anyone else has had to deal with this. Unfortunately I haven't verified if the front USB will charge a phone. This is my next step.

My front USB also doesn't work. I even got mini to standard USB cable with unit, but plugging flash drive into it doesn't produce any reslt.
I also plugged extension cable to one of back USB ports and tried it (plugibg same USB flash) but it doesn't work either.
So I'm also confused.

Does that mean you are still running the stock ROM? I have been hesitant to install the custom ROM because they say you must be able to get into the bootloader even though I couldn't find a step in the process that required it.
Regarding the USB ports not working at all, you may find that you need to use a powered USB hub. I've seen reports of USB devices acting up due to the low power. This is one of the reasons I thought it might be safe to use the rear ports with my computer. (My first real test is going to be mangling a male-to-male USB cable so only the data lines are connected to see if I can get those rear USB ports to talk to the computer. I figure that way there is no chance of frying any circuits.. Each side already has its own power and I don't believe any signaling is sent via the power pins.)
On my unit (MTCB-KGL-V2.80), I have used a T-Mobile USB broadband modem successfully on the rear port, so I know rear ports are live. I did take it apart to see if something was obviously wrong with the front port, but nothing jumped out at me.

So I have a bit more information on my headunit. BTW, I have the BMW E46 model with MCU MTCB-KGL-V2.80.
On my system, both the front USB port and the rear 3G USB port are wired as device ports connected to an AU6258 USB controller (http://www.sunnyqi.com/upLoad/product/month_1403/201403162331285643.pdf). I don't remember exactly which USB ports they are connected to, but I believe the 3G port is connected to port 2 (pins 6 & 7) and the front USB port is connected to either ports 3 or 4 (pins 9 & 10 or 11 & 12 respectively). Nothing is connected to port 1 or to the upstream port. The other rear USB port is wired directly to the MTC_RK3188 board.
All three ports are wired with only four pins, so I'm concerned that none of them could work with the computer. The USB controller doesn't have USB ID pins, so does that mean that the 4 downstream ports are OTG and the upstream port is for a computer? Unfortunately I don't know the hardware side.

No I flashed Malaysk ROM from GPS SD card. No problems. Just follow instruction. I had luck that I didn't need to recover from USB.
Did you tried with USB powered hub? I don't have one to try it myself.

I checked on my Linux workstation with
Code:
lsusb |wc -l
plugging and unplugging all three USB cables and the number did not change. BTW where did you use the "adbon" command? The only place that I could even try was at Settings > Factory Settings. Regards Flint
