USB Port???

I just replaced the ROM on a Qtek 2020i. It took me a day and a half to get it done. I tried everything I could think of to make it work. It got stuck in Bootloader mode and nothing I tried would work.
I finally use a different USB port on my computer and BANG, everything worked fine.
Does anyone have an explaination why using a different USB port made a differance? I'm at a loss to understand why.
Hope this helps others that are in the same situation I was in.

at times windows try to install drivers and it goes wrong
drivers for usb devices are tied to the usb port they are connected
to and moving the device to another port reinstall the driver

Help connecting Epic to pc (yes I used the search and my issue isn't resolved)

Ever since I rooted I can not get my Epic to connect to a computer period. I'm about to give up and just deal with what I got, hopefully someone can tell me what I'm doing wrong. Before anyone decides to be a smart ass I have used the search function literally for days and have tried tons of things recommended with no result. I am the first to admit I'm an idiot when it comes to anything involving computers but I'm pretty determained to learn.
This has to be the phone because I have tried to connect to 2 desktops (1 running Windows 00 and 1 running the most updated Ubuntu), and 3 laptops (Windows xp, Windows Vista and Ubuntu). When I rooted I used the Vista computer and connected fine (can't anymore). I didn't have the space on the C drive to install the Android SDK so I switched to Ubuntu (first time user btw lol). Somehow when I was backing my SD card I lost any access to it or the notification bar. I never got my SD back til I rebooted but I haven't been able to connect to any PC since. When I charge (even in the car) it always tries to stay in mass storage mode. I basically charge in my car with my phone off hoping it will just charge and not mount my sd card to my car or wall lol. Yes I wiped 3 times, partitioned sd, tried several different cables (but my husband used mine and no problems on his Motorola) I'm sure I've done something wrong when I rooted or mounted to Ubuntu.
I also can't use adb. I followed the directions to the t (a few times lol) but when I run any commands it says "no such file or directory" I didn't have adb on the windows pc when I di noobnl's one click so I never ran the (adb shell ect) commands. I now can't do jack. I am now running noobnl's DI18 ROM with modem.bin flashed thru Clockworkmod.
I have tried all the basics you will find wit 2 days of web search.
My goal is DK28 (dream on Erica lol)...Thanks for any help and for anyone sparing me a lashing ;-)

When you plug in on your windows pcs...in Device manager..do you see anything appear? also do you have USB debugging on the phone?

USB debugging on?
Have you tried reinstalling the drivers for the Epic?
Rebooted phone and PC? (Sometimes it helps)
Used Odin?
Something might have been screwed up during one of your downloads, bad file maybe. Try reinstalling your drivers first, use Odin (phone must be in download mode), and see if it recognizes te device. If it does then Odin the stock .tar file and go from there. It'll give you a fresh start.
That's all I can think of right now.

I bet your USB debugging is on since most root's requier it. Even tho it says connect to pc if usb debugging is on it wont connect to my windows 7 box

I would suggest, if you're really having this many issues, just boot into download mode (1 on the keyboard + power button) and odin back to di18.

Just for kicks have you tried Settings > Privacy > Factory data reset? I assume that wiping does the same thing if not more but it's worth it to see if it somehow resets a setting that might be the issue.
What's left - software issue or Hardware issue.
Software:
hmmm...yeah gotta try connecting through Odin which uses downloader mode instead of USB modes...
Can Odin see your phone? Run Odin as admin with antivirus off, and proper samsung drivers installed. Then boot phone holding down 1 key into downloader mode. Connect to computer through USB port on back of computer (i.e. directly to motherboard) - does Odin identify something attached to USB port?
Yes - flash the dk28!
No - with Odin still on, unplug the USB cable, pause, and reconnect it. Still No? Try a different USB port on computer. Also try uninstalling and reinstalling the drivers - be sure to reboot the PC. If still No, then try on another computer, and as you did before, try different cables. Still No?? --> hardware problem with phone.
Hardware problem with phone: Look at the usb port in the phone - is there any junk in there that might interefere with the connection?
Yes - clean it out
No: phone perhaps internally damaged:
Solution for hardware damage:
You and husband clean up and go to sprint store.
At store - tech will know phone is rooted, so:
--Tech more likely to like you? You handle it, maybe even blame husband. Husband can silently attend and look sheepish, playing the part of 'me man, me dominate environment, me break fancy tech of wife, me sorry." Try to get free replacement phone while simultaneously promising never to let your husband root the phone again, or even touch it.
--Tech more likely to like husband? He goes alone, cops to the true story of how you rooted it and then was backing stuff up when it suddenly stopped working [truth from men? so sincere!]. Try to get free replacement phone while simultaneously promising not to let you in the house should you even attempt to root again.
P.S. forgot to add you might turn off the PCs firewall while testing, as well.

same here. I tried out the free tethering app the other day and with usb debugging on i coudl never get it to install the proper drivers. Without it on and the 64bit drivers installed Odin worked just fine.

I have seen many Galaxy S devices not connect to a computer because of a faulty USB cable. Had my girlfriends sister switch out 3 Vibrants only to accidentally try and connect it to a laptop with a different USB cable and I've seen two others not connect with the stock Samsung USB cable.

How I fixed the tethering issue
I've had the same problem with my galaxy s - connecting to the PC (Win7 32bit) just doesn't do anything. As a test, I had a friend with the same phone/rom (froyo, rooted) connect - and he was able to! It installed the drivers and it just worked. He disconnected, I connected, and now it's fine.
So, see if you can find someone with the same phone and see if they can connect. Makes no sense to me, but it worked.

I've had my Epic fail to mount before. Interestingly any time I had an issue it was with a Mac - it always mounts on a PC. I'll stop now before I open up a can of worms.
Best advice I have is get a Dropbox account. You can use that guy to move files from a computer to the SD card without having to mount to the computer. Perhaps you can get a factory ROM (with root of course) on your phone that way?

You can get a app from the market called SWIFTP (free) & connect to your sdcard via ftp server. This can be a temporary fix till you get your connection error resolved.

I have 1 USB port on my laptop that the Epic shows up as "unknown device" on. Works on every other port, and everything else works just fine on the same port. The factory USB cable is finicky!

USB problem with HTC Desire HD

Hey guys,
I currently recently installed a custom ROM from this website and for some reason now when I plug in my USB into my PC it comes up not being detected so when I put my phone as hard drive so I want to transfer music, it doesn't detect it. Can anybody help me if this is ROM problem or just my USB?

Hey,
Okay I disabled USB debugging didn't know it was on, still doesn't work says windows cannot find USB device not reconginzed when I connect the USB. For the Reinstalling usb driver I do not know how to this ~?

i have the same problem.. turn "fast boot" off and restart the phone.. this always works for me.. hope this helps

Hey, I turned fastboot off. Doesn't work. I ordered new usb cable.. hopefully this works and it was just a fault with the cable!
Sent from my Desire HD using XDA App

Usually this is a problem with the cable. Simple, cheap to fix. Keep your old cable around for charging though (nice to have a spare)

Is this problem with the USB still active?
If so try a different PC just in order to eliminate WinOS issues.
If not close.

Hi,
I have the same problem at some months ago. I tried the cable and pfone on another PC, and it works fine. So, I recommend to try it on another PC and reinstall your Windows.
brgs,
Herold

Had the same propblem! Turns out it was the usb cable, it charged fine with the cable but data transfer didnt work.

i also had the same problem since last week and still cant resolve till now...i try all the option that u gave(change cable/pc,turn off fastboot)....i even sent my phone to shop and they still cant detect.they said maybe the usb port is damage or some software that may block my usb port?is it true? anyone can help?????

What happened last week? Is that when you got the phone? Or installed a different rom? etc.

USB BRICK in my INSPIRE 4G ( DESIRE HD)
Hi, all
I got a new inspire 4g last week.( equivalent to desire hd ). It was working fine. But now it does not detect the USB connection. It only charges when I connect to pc. No other issues. I have also noticed that during fast boot mode also pc does not recognize the phone as device. I have tried all the suggestion on xda but no luck.
As fastboot is also not detected by PC I could not format mtd0 and reconfigure it.
Can anybody have any other idea? If I change the main board how much cost will incur ??
Thanks all.

First of all.. you have HTC Sync installed right?
Happened to me initially as well.. although for me changing the cable and/or changing the USB port on the PC solved the issue. Have you tried these?
Also sometimes killing all apps on the device before connecting helped.
You can try accessing your device through ADB to see if its being detected.
And I really dont think you'll need to change the main board..

USB brick on my Inspire 4G
Thanks for your reply. When I go the phone ADB and Fastboot were working
well. There was no driver issue. Now even PC also does not detect the phone or any new hardware when I connect it to pc. I had working fastboot on both win7 and Linux (ubuntu) pc. Now in both OS the phone is not detectable. Windows device manager does not see any new hardware when I connect my inspire . dmesg also does not show my hardware when I connect my inspire to linux pc.
Please help or suggest me to investigate further. I know how to install and work with adb and fastboot as well as Clockwork recovery ( also ext recovery). Some people suggested to flash a new radio. I can flash the new radio via sdcard. But how safe is it ? My phone is S-off and made unbranded. Will flashing a new radio make my phone locked AT&T again? ????
Thanks a lot

As far as I know.. USB problem has no relation whatsoever to Radio. Radio is only concerned with the signal stuff. Flashing it isn't that risky if you follow the instructions... There's a thread in the development section about Radio's which explains it pretty nicely.
As for the USB problem, are you using a Custom ROM? Some ROMs like LeeDroid have USB detection problem which can be solved simply by flashing a different kernel like LordMod's.
What I meant by "Accessing through ADB" was if commands like "adb remount" or any adb command as such are working when your phone is connected to the PC? Or is it showing "error: device not found"?

usb doesn't work

hey, my sgs+ can't connect to the pc. it allows batterie loading, but connecting via usb doesn't work. i've tried a reset, reinstalling ROM, the usb modes (kies etc.), i've tried another cable and another pc. what shell i do?

what do you want to connect to? for kies i don't know. never used it. otherwise you got to change your usb settings on your phone
btw: this is a development forum... ask somewhere else... the i9000 guys can help you with this too

May be something wrong with your phone usb port, some contacts not work.

First of all, you should tell if you are using a stock rom, other problem uses to be the windows driver, it does a wrong installation or gets corrupted sometimes.
Try reinstalling the driver, or if you are on a non oficial rom, try another one, or an oficial one, but remember to save your efs folder first in that case.

[Q] Windows will not recognize Note 3 anymore, help please!

Hey guys,
Just recently, my PC and any other PC Ive tried for that matter will not recognize my Note 3. I had Windows 7 and it worked fine for months, then just the other day it came up on the bottom as USB Device Not Recognized, and no matter what I do it will not do so. Yesterday, I upgraded to Windows 8.1 and still the same result. I have installed Kies 3, uninstalled and resintalled Samsung drivers and still nothing. I am running a custom rom in the stock slot using Safestrap...is it possible that that might have messed up something? Even when the cord is plugged into the PC, the phone doesnt come up with anything notification that it's plugged in, but it does say it is charging. If any of you have any tips or something please help because I am at my wits end.
Thanks

Have you tried with another cord?
Computer doesn't see device... Device doesn't detect plug in... Sounds like a bad USB cord

Yes, actually I have and still nothing...forgot to mention that in the original post.
It's a strange problem which leads me to believe that something has gone wrong in the phone, or that I caused something to go wrong by flashing a rom or three, since it did work previously. Unfortunately, I'm at status: Custom, although my Knox is 0x0.

Yes, this shows as disabled. What should this be?

Can't help you solve your problem, but last night I had a hiccup where I plugged my (17 day old) N3 into my computer in a USB2 port and ... nothing at all. (As if it were electrically disconnected - no "unknown devices" showing)
Tried it in a different USB2 port, and ... nothing.
Tried in in a USB 3.0 port - same computer, same OEM cord - and everything was fine. As far as I knew, nothing had changed on either end of things, although the previous evening I had used a different OTG cable for a USB key with the phone, and I had also had a automatic update of the Samsung Push Service on the phone. Nothing had been plugged into the PC's usb ports since it's prior cold boot. (Win 7 x64 Pro).
This morning (both PC and phone have been rebooted), everything is back to normal - both on the phone and the PC. Both the USB2 and USB3 ports all seem fine.
Ugh. Makes me nervous - brand new hardware.

Boot into Odin mode THEN plug the device in, let windows find the drivers for it then once that's done, reboot the phone regularly and see if it works then. It appears to be an issue with most to ALL Samsung devices, but this worked for my wife's galaxy S3 when the computer wouldn't recognize it and the phone didn't detect a PC connection.

Did you fix this problem?

Thank you! Worked perfectly!

I have the same problem, do you have any solutions ? Thanks.

I too have been struggling with this problem. The is no USB symbol in the notifications area on my phone whether I plug into to my computer at work (Win7) or at home (Win7), using a usb3 cable or a usb2 cable. Its as if there was a setting on my phone that allows recognition when plugged into a computer that has been turned off.Is there such a setting? I would love some help on this as well. Thanks in advance! I am rooted with towel root and have had no problems until last week. When I look in the device manager on my computer it shows :
SAMSUNG Android Phone
SAMSUNG Android ADB interface
I tried uninstalling the above and then plugging my phone back in and it re-installs the same driver shown above.
For what it is worth here are the drivers for SAMSUNG Android ADB Interface:
c:\windows\system32\DRIVERS\winusbsys
c:\windows\system32\WdfCoinstaller01007.dll
c:\windows\system32\WinUSBCoinstaller.dll
Should I be using different drivers ? Thanks|!

please help!
any solution yet? i have same problem, no usb detection and camera wont work i want to flash stock rom whit odin but i cant get the computer to recognize my phone...

I was able to fix the usb recognition problem. i had to do a factory restore. I lost root but gained usb recognition AND the Over the Air update to 4.4.4 and patiently awaiting the update to 5.0 hopefully this month!
