Hello
I'm having some USB problems:
The device seems to disconnect after a few minutes, sooner with intense usb activity (like copying files)
I tried with 2 cables, 3 computers and with both XP and linux
However 3 days ago it didn't seem to act like this, altough at the time I didn't use the device so much (I was busy exporting/importing the contacts into HTC)
I tried hard reset, didn't work
I can only think of 2 possibilities: either there is a problem with the usb driver in the device, ori there is some problem with the electrical connection somewhere on the device
So, the question is - does anyone else experience the same problem?
Thanks
I think, that device disconnects when it goes to sleep mode (my device does it). When it is on USB, it acts like it it on charger, so simply make charger sleep time longer. It is quite annoying, but only solution so far.
No, it's not that, my device doesn't go to sleep when connected to a power source, anyway I tried to disable sleep mode completely and it still gets disconnected.
Interesting, the device still belives it's connected (I see the icon at the top of the screen), but the PC end is down.
Never had such issue. Maybe you could try to contact HTC Tech Support... But as the hard reset didn't help, I'm sorry to say, maybe you should consider a warranty claim. Might be a bad connector or something.
Ups sorry, i didn't read correctly the original post.
Maybe, it´s will be the energy-management from PC?
Look in device-manager in the properties of the USB-Port, try to disable the "Energy management". Please post the result here.
Greetings Mirko
Tried that too. Same result
Hello 4EST,
please use only the origional USB cable to connect PC and XDA! You got to pull the Mini USB side as you can´t see the silver part!!!
The connetion lost when you act at the cable?
Somethimes it seems only to be connectet right.
Greetings
Rescue01, I used the original cable, the problem is exactly the same.
Here is an update:
I sent the device for reparis to HTC. The device came back "reflashed", but the problem still pesisted from the first power-up. In other words, they fixed nothing, didn't even bother to check if it worked right
I sent the device back again for repairs, very angry, talking to the call center. This time they opened the device (I can see it on the screws), did something to it, then reflashed the device again.
And it worked perfectly, with all the cables and the computers I tested before........for a while....... Because after ~4-5 days of usage the problem started to reappear more and more.
Now, as I just tested, the USB gets disconnected after only 5sec of reading from the device. Sometimes it lasts longer, like 2 min
So my opinion is that there is an electric problem, I would guess with the USB connector
Unfortunately for me, the service center even if they fixed the problem last time, they did NOT checked for it before fixing it and assumed everything was ok the first time and blaimed the USB cables/computers for the problem. They said something like "sadly, after checking the electrical connections and reflashing, the device works perfectly". And it did for a few days...
Here is an update:
I send the device for the 2nd time to the service center, this time calling them angry about not fixing it for the 1st time.
The device came back quickly. This time they opened the device (I can see it on the screws), and the USB connection actually WORKED!..........for a while.....
After 3-4 days it started disconnecting again, having less and less USB connection time.
Now I have to try to get it conencted, as sometimes it disconnects right after connecting

Ok so my Vouge's screen busted on me and I was using mymobiler to use the phone till I got a replacement. Now I have a temporary phone and I will be getting an HTC HD2 and I would like to get everything off of my Touch and on to the HD2.
Problem is all of a sudden my phone does not want to connect to my computer with either ActiveSync or MyMobiler... I did not change anything that I can think off. The only difference I have noticed is before the phone use to stay lit up regardless of how long the phone was connected to the computer. Now all it will do is show the charging light but the screen dims after a a bit and then eventually turns off but still shows the charging light. As long as I have had this phone it never did this while connected to a computer it always stayed light up...
Is there anything thing I can do to get this to connect again?? Any help would be great, thanks in advance guys...

Have you tried to soft reset?

It might not do anything but it is worth a shot anyways. Take out the battery for a couple of seconds, put it back in, and turn on the device. Then, connect it back to the computer, but to a different USB port than the one you normally use.
Yeah I have tried that to though I used the same usb port so I will try it again after work... I don't understand what happened it worked fine like a week ago now nothing... I really would like to get the stuff off of it. Sprint told me the port may have went bad and I am going in Friday to have them look at it but still doesnt't seem like that is the issue.

I agree, otherwise it wouldn't even charge.
Yeah that is what I was thinking... but then again it is acting like I am using the wrong USB cord. Like I have a mini usb cord for my external hard drive and if I would use that it back when my phone worked it would do the same exact thing, just charge and not connect.
But I am using the cord provided by HTC and I even tried using my digital camera's cord because I know that one would work to before. Nothing... This is pissing me off I don't understand why it randomly doesn't want to work after 2 years of no issues...

Well, it could be that the reason why your screen failed was because of a problem with the electronics (board on the phone) and after such a long time using it, it finally gave up. Kinda like riding in your car with a nail in the tire. You can keep going, but eventually... it will give in.

It could simply be that something shorted. Have you tried to attach it to another computer?
Yeah... I guess I'm screwed unless the sprint store can do something for me when I go in there
Have you tried a different PC? (doubt this is the case, but...
Hello
I've got an HTC HD2 tmo US...
When I plug in the sync cable from the phone to the PC, simply nothing happens.
The phone charges but Mobile Device Center shows not connecting and nothing about detecting hardware or anything, when I set the phone to ask what to do (ie. Disk Drive or Activesync) It also doesn't ask anything when plugging in.
Any ideas?
First check the phone with another cable. Are you using the supplied USB to micro or another cable - like a retractable? I made the mistake of buying a retractable that wasn't fully wired to handle data.
Uninstall Activesync and reinstall with the phone disconnected - they once the install is done reattach.

Hey
Yup, I tried another cable, both are official HD2 cables or OEM...
I have also tried another PC (32bit WinXP) - still no detection.
When I press volume down and power for 3 seconds, it gives me that tricolor dislay, i tap it and changes to USB, my PC then sees the phone (but of course not usable).
So I think it's software related, I'm trying to flash with the SD card, but so far it's just stuck on Loading....
Any other suggestion you might have perhaps?
I've managed to figure out it seems to go into car kit mode everytime I plug in the sync cable, and NaviPanel pops up some times. Looks like it's a tad buggy though cause it won't go away and then it goes away and comes back, etc.
Any ideas?
stuck in car kit mode is indicative of a faulty usb port. some people have had success by cleaning out the port with various means,,, compressed air, wd40, toothbrush, one aguy even spat in it.
mostly, though, it requires a warranty repair.
theres a thread "stuck in car kit mode" in the regular hd2 general section.
That fixed the issue! Toothbrush, yes I failed a few times, just kept watching the screen and got really in there hard and dirty on the top small gap, and wala- the light came on while it was locked and it worked.
Is this a permenant solution though? Is it really only dirt and something that is just for maintenance sake or should I be worried the hardware is faulty or on its way out?
Sorry, couldnt say. Sent mine away for repair and they swapped out teh whole board. Plus minewas deffinately clean as a whistle. It seems some people have dirty slots, some have hardware faults.
Have you tried messing with the USB to PC settings?
Settings > Menu > All Settings > Connections > USB to PC > Either pick Activesync or Disk Drive.
Sometimes my computer doesn't do anything when I plug in my phone using Activesync. I would have to open up Windws Mobile Device Center and detect it manually.
USB debugging no longer activates on my phone. Activating it in settings/applications/development brings up the "Allow USB debugging?" permission window. However, no usb notifications appear, and the phone appears to be a dead device to any PC it is connected to.
This started when I accidently got into the download screen from the phone options popup. The display showed the yellow sign, android guy with shovel, and message warning not to turn target off. Phone was not connected to anything at the time.
Searching found a couple of threads indicating that a battery pull was safe to get out of it. Did same.
Since then, usb debugging (or usb anything) has been dead on this phone. Other methods of usb access (thru usb settings) have no effect either.
Tried the following...
(1) restore to my last backup rom.
(2) numerous reboots and battery pulls.
(3) mount/unmount sd card in cwm recovery
(4) clear caches
(5) changed pc's and cables (all worked before)
(6) reinstalled usb drivers on pc (worked before, didn't expect it to help since issue is at phone end)
As you can see, I'm running out of sticks to poke the horse with. Does anyone have any ideas?
Update: new kernel didn't help, either
Update2:
(a) Can't do a restore via odin, which won't detect the phone.
(b) Updated my adb (which I don't use much). adb devices command will not detect the phone via usb.
(c) Installed adbWireless which allowed me to push a stock nandroid backup to the phone. Restored that, usb is still dead.
(d) Restored back to my superdark rom, usb is still dead.
Head scratch: I'd blame hardware except that it seems to be between the settings and execution. If it was purely hardware, I'd expect to see the usual usb notifications. Regardless, it looks like I'll have to revert back to stock and let Verizon figure it out.
Update3:
(a) switched to the new AOSP rom. Nice, but no usb.
(b) switched back to superdark since I like my speakerphone and the AOSP seems to be on hold. Still no usb.
Resolution:
My apologies for not posting a resolution. My bad. After the first few days the post kind of fell off the radar and I stopped checking.
Short version...dirty usb port.
Details...after a week or so, I saw the usb icon flash in the notification bar for a few seconds when I plugged it in for a recharge. Hadn't seen that in a week, hope springs eternal!
A thorough cleaning of the usb port using a paper swab dampened with alcohol restored usb functionality. Not much dirt came out on the paper, but it must have been enough to probably bridge the contacts somehow.
At present the phone is fully functional. The original Verizon cable seems to be a little wonky. I have an aftermarket cable that works fine. It may be that the aftermarket cable did some physical harm to the contacts in the port, or the original cable is going bad (I had something very similar happen on my Omnia). Not sure.
I now use the original verizon cable only for charging at work and use the aftermarket cable for usb connecting at home.
Bottom line...if your usb goes dead as described in the op, carefully clean the port.
My thanks to all who responded...
Download screen shouldn't have harmed you.
You probably are well aware of this, but sometimes it's the simplest solution: Is your usb cable unplugged when you are trying to turn on USB debugging? It will not let you if you are plugged into a pc or mounted for some other reason. Make sure your file manager and any other rogue app is closed. Again, it does sound like you have tried all of this, just giving my best shot ar an answer.
Other then that... Has anyone else had this problem? I haven't seen it in this forum before.
The most general solution to any issue on these fascinates is to undo whatever you did to break it, it's just difficult sometimes to isolate what that event was.
Swyped w/ XDA App. When in doubt, mumble.
Thanks for the reply.
USB is unplugged when turning on debugging. I've also tried turning the phone on with usb plugged in.
The last thing I had done (before accidently activating the download screen) was to install SiMi Folder Widget. Needless to say, it went away with the rom restore.
Also used ATK to kill running processes before turning on usb debugging. Also verified that I still have root.
I've buggered the phone up before but have always been able to figure out a way back (with help from forum searches). This one's got me stuck.
Tonight I'll try to figure out if it can be odin'd back to stock and rebuild from there.
Again, thanks. All suggestions/advice are appreciated.
See op for steps taken to (unsuccessfully) solve this.
Can anyone advise how I can flash back to stock DI01 without using odin, since it won't detect the phone? I can push files to the phone via adbWireless but that's about it.
thanx in advance...
I dont know if you fixed it or not, but here is a stupid question. Are you using the cable that came with your phone? I have several cables that will only charge my phone and only the stock one enables data transfer. Hope this helps. Good luck

This may be my problem! I'm having the same similar effects. Although mine randomly shows the symbol but also says my usb is connected when it does. I've been trying to solve this for 2 weeks now! I hope this is the solution.

common problem
This must be a common problem because I've had the same issue. switched cables and viola, all good.
My exact problem solved:
USB debugging activated on phone but computer did not detect it at all, nothing what so ever. Not even on dial-up mode, or download-Odin (yellow triangle).
Drivers installed (Fascinated and Nexus for the hell of it).
Tried to ADB my into it both from windows 7 and MAC OS-X.
Hell I even tried a different USB cord.
I would get the USB debug icon in the status bar only when on windows7 machine.
I cleaned the phones USB port with the alcohol damped paper towel/tooth pick and the **** worked, first time.
Man I gotta thanks God for this site. I been ****ing with for 2 days.
Then this lil SOB acted as if nothing ever happen. I wanted to beat the hell out the lil ****er. But we are back friends now.
Thanks dude. This **** needs publicized more. I went through a few links before I found this.
I would and tell people to use something non-metallic and removed the battery beforehand. I did just to be safe.
Following on from another thread I posted about problems after updating to Android 8.0.
I have now discovered that I cannot actually connect my device to any PC / laptop.
When I do, it either doesn't register as being connected, on either the laptop nor the S8 (doesn't charge) or I get a pop up telling me its slow charging and I do not see it within Windows.
This means I cannot transfer files from device to device nor run any adb commands, which, oddly, id like too.
Has anyone else seen this?
Ive tried many things, including:
reboot S8
clear caches on S8
tried different USB cables
tried different usb ports
tried a different windows machine
changed settings in S8 developer options (set to MTP transfer)
update windows drivers
uninstall and re-install Samsung drivers on windows machine
Nothing seems to work anymore.
Occasionally if I plug it into my Windows machine, Windows gives me some sort of error message about the device not working correctly and so cannot be used?
Any help would be much much appreciated, as my device is no bordering on being completely useless.
And the Samsung customer / tech support is literally THE worst I have ever experienced.
Thanks

Thanks for the link, I'll check it out.
But it doesn't help me really. As I can not get windows to even see my device, not does my S8 acknowledge that it's plugged into my laptop.

and today I woke up to a moisture detected notification...so cannot cable charge at all now.
My S8 has never even been close to liquid of any kind, always kept in a fitbag sleeve case, inside my pocket.
F**k this phone and F**k Samsung and their crappy Android update.
A crazy expensive device that is now rendered pretty much useless due to their last update
to summarize, following the Oreo update:
- cannot cable charge at all now
- previously could only slow charge via cable, fast charge would not work
- cannot connect S8 to any other PC / laptop to transfer files
- battery life is absolute garbage - need to charge 2 times a day at least
- WiFi is laggy, slow and drops connection
- Some of my Cast devices (Google Home and Chromecast) are not seen by the S8 - have to disconnect and reconnect to Wifi several times
- pretty sure the phone is randomly rebooting (every so often I'm asked for my PIN rather than biometrics)
Last update 10.05.18 - G950FXXU1CRD7
Im sooooo glad I have 1.5 years left on my contract with this phone....

nope!
Took it into my providers (EE in the UK) store, and they were about as useful as a chocolate fireguard..."have you tried turning it of and on again innit"....
after lengthy discussions, in which I explained more than they did, it has been sent for repair.
Could take up to 14 days, depending on the fault.
From what I can gather by Google fu, the moisture alert is a common fault, and ive come to the conclusion that Samsung f**ked up the Oreo update / roll out, but are burying their heads and forcing the carrier providers to take the brunt of the complaints from the end user.
Bad form Samsung, BAD FORM
I think this S8 will be my last Samsung device. Ever.
Im have the same problem today i realized i cannot connect to pc through usb and i cant not fast charge only slow charge when i connect it to usb port it starts charging but cant transfer files or flash another firmware to try to solve the problem?
so did they find the problem?

How about the USB Debugging of your S8, after upgrade to Andorid 8.0, the USB Debugging may be disabled.
