Usb is not working on my polaris. When i connect it to my computer nothing happen. The computer wont eve recognize that i connected something. I have tried to hard reset it, but it didn't work. I have flashed it with c_shekar v3 rom. I also have radio rom v. 1.58.25.14. The usb port has worked great for some time now, but suddenly it just didn't work.
usb problem
I had the same problem and the solution was really bizare. I let the phone into the usb, charging and after a while i heard that usb pluging in sound and imediatly after that the usb pull out sound, then after some time it happend again, and again. The fourth time i think the connection was stable and activesync worked. I did nothing, weired , i know but this is when windows meets windows through another company. Oh, and see if the usb on the phone is clean.
I did try to clean the usb connection on the phone, but it didn't work. I have also tried 4 diffrent usb cables. I am trying to flash another rom from the sd card, but that isn't working either :S The phone have been connected to the computer for several days now, but nothing happens. Maybe the moisture in my skipants killed it? (I spend at least 4 days a week on my snowboard) Maybe I'll just use it for skiing and dh, and buy a diamond for normal use.
Recently we have been getting in stock i997's that are having USB issues connecting to the computer. As always we enable USB debugger and connect to the computer however now the units are going into charge mode a few seconds after connecting to the computer and shutting the device down. Once we disconnect the device from the computer it automatically restarts.
Here is what we have done so far with no luck:
-Enable USB debugging
-Disable USB debugging & enable mass storage
-*#7284# was set to USB=PDA, changed to Modem & back to PDA
-*#9090# Didn't see any relevant options
-Slightly bending the USB port
I don't think it is a hardware issue but a software issue that needs to be configured. Any help would be very much appreciated!!
USB
Get it as stock as you can with software. If the USB still does not connect correctly then it is a hardware issue. There was never a problem in any stock rom with USB connectivity.
Just my thoughts. It may not be the phone but the connection-- Computer, cable, oops,-- or drivers.
I'm facing the same problem !
I too have the same problem very weird tried several time stock have no issue in connection. this issue occur after few days not immediately and no regular pattern so can't say what's going on. right now my phone while put on charge shows charging but when un plug it still have 1% as charge no battery put to charge message shows up, tried with charger, usb to computer.
I also noticed before that charging stops and only come in effect when you pull the battery and plug the cable put the battery it will start the phone automatically and charge start up.
Can't ever put in charge in switch off mode as every time it automatically switch on my phone.
I tried several time these step 1. Go back to stock by heimdall , 2. heimdall kernal flash for red cwm, 3 wipe, format, fix permission 4. flash
couple of days work smoothly then problem reoccurs
Did you try mtp mode like with media player mode

Thanks RDomke for the reply.
We already flashed UCKD5 with no luck. Would there be anything else we could do? I agree that it may be hardware if stock doesn't work but we have been getting in too many units out of box with this issue. Not saying that it isn't possible to be hardware, just seems like it's something that could be software related.
SOLVED

RDomke,
Many thanks as we have solved the issue with your advise. The 1st unit we were testing did in fact have a bad usb port. Once properly diagnosed we tested another by flashing it back to stock and then performing a factory reset. Once done issue was solved and worked on many other with same issue.

Anyone?
Also would HTC Desire charger work with it? (the sticks looks same - microUSB, but looks like the phone is not charging)
Also if the phone is dead, is there any way i can check if the battery/screen or whatever else is faulty?
When i connect it under Windows with USB cable, it says that the device cannot be recognized and the drivers cannot be installed.
When connected with USB, i did hold the power button to turn it on but it doesnt start and the phone keeps vibrating continuusly.
Look on the back, or inside, even under battery, for more information.
I already know it's Samsung Galaxy Mini II, homever i have issues turning it on.
All microusb chargers are the same except for amperage. Try all you have. This phone is probably terminally damaged, but try a new battery if possible.
It's really strange (the phone was little wet) homever, sometimes it's starting just fine and sometimes wont turn on at all.
I have removed battery and put it to the bowl with a rice for a night and will see if that helps.
My "dampness" recovery is to disassemble and put phone/tab/laptop in in very low oven ie 125-135 degrees F for several hours. You may have ti turn oven on & off manually to get that low temperature. Your mileage may vary.
OK so basically the phone is in following state:
It's charging fine, homever the biggest problem atm is i cannot get the usb mass storage to work.
I'm connecting it to the PC and the phone is detecting it as AC charger not USB - PC is not even trying to install any drivers.
PC is not detecting the phone at all (phone is detecting that its being connected, the button backlights are lighting up)
I got no dropdown in the phone to select charging, mass storage etc. (when i do it in settings/communication/usb settings it keeps saying to connect the usb cable, but the phone is charging so its connected just fine)
When i was connecting it for the first time windows tried to install drivers but failed, also it was constantly disconnecting the phone from usb cable (now its fine it seems)
When i connect it using "Kies Air" it's working homever i still dont see the SD Card in "My Computer" for example.
What a mess, anyway any idea how to get the USB working again?
Try different cable, and/or different PC.
I ordered new usb cable, homever i doubt it's the problem as the phone is recognizing connection and also it's charging fine.
Something's wrong with my USB Port.
since about 1 week I installed new Custom ROM, so, from KOT49 to KVT49.
Sometimes it charges normally, sometimes I need to SHUTDOWN device so it charges normally again.
USB connection(USB DEBUGGING or Normal) it constantly connects and disconnects from PC.
What I just noticed is that when N% is connected to PC, kinda pull down Status/notification bar is laggy or it's not responsive.
Is it may usb port faulty?
regards
EDIT:
On FASTBOOT MODE it doesn't disconnect at all, so, don't know if it's USB PORT related
I have a MTCD head unit MX (witson) with Android 5.1, my problem is that the USB port cannot recognize my phones, A note 4 with Android 6.0 (eRobot ROM) and a Samsung GT386T no rooted with stock ROM 4.4.2. The USB port works find with a usb stick, I can play music, pictures, etc. but not my phones. Both have the USB debugging enable.
When I plug a phone it is charging but nothing happens, my note 4 after a few minutes pop a windows saying that there is a problem with the connection MTP and that I need to download samsung Sync etc.
What I want to do is to use the mirror link function.
Any of you know something about this issue?
Thanks in advance for your help.

I believe i read that there is a specific app that you have to run on these to do the mirror link...easy connect, maybe? Did your HU come with an instruction booklet? I was looking through mine earlier and it went over in detail how to setup mirroring through that app.
Yes, when I tried to use EasyConnected is when I saw the problem. The app waits for my phone to be connected, It says that it must be turned on USB debugging, but it is on. Then I checked in the File manager and the USB was not enable there, like if nothing is plug it. If I plug a USB memory it works fine.
I will try today to do a factory reset.
Thank you!

You ever get this solved? My easyconnected never stays connected. WiFi and USB both are garbage.
WiFi randomly disconnects.
USB also disconnects asks me to allow USB debugging every couple of minutes. The phone never remembers the headunit, so it constantly asks me again to allow connection. Must be a crap RSA fingerprint coming from the headunit.

Nope, Still does not work for me. Same symptoms as you. I already tried with 3 differents phones, factory reset and different versions of easyconnected.
I seem to have USB connection working now with only one "allow USB Debugging?" popup, only when I first connect.
What I did was turn wifi off on the headunit. I am not sure why it worked, but I just wanted to turn everything not needed off, and see if the headunit would stop disconnecting all the time. So far so good. I can probably live with one annoying popup, instead of one every few minutes.
Of course you have to keep the screen on the phone on, and the battery in the phone will deplete faster than the headunit charges it, but still an improvement. I had a 30 minute drive today, and the USB never disconnected!

paniqueado, try the da_anton ROM. I just installed it and easyconnect finally works as it should. I just plug in my phone to the USB and it fires right up! One prompt if any on the head unit, and NO disconnects whatsoever.
