Just one more shot, go to active sync/windows mobile device center and see if you have "enable usb connections" box checked? that's in archive>connection settings

Its possible its a faulty wire. My mom and I had regular USB, and they were horrible. We got docs for them and they sync alot better.

Bruv, I have your same phone (made in taiwan) HTC s621 and I don't use the original USB cable, I use a motorola cable...I even used sometimes a digital camera phone usb cable (since some of them are standard) and sync everytime with no issue at all. Try what I posted before, if not reinstall activesync in your PC.

usb connector only charges the battery, but any other function works

hello everybody
well as the title says, my touch pro 2 from t-mobile doesn't work properly.
without a reason the usb connector stop working, only works for charge the battery, activesync, storage, internet sharing and others thing uses the usb cable doesn't work, I don't know if this is a know problem or is a malfunction of my device
PS: I am using the official WM6.5 from HTC.
thanks.

Try a different usb cable, different usb port, reboot pc and try a different pc. if none if these fix it it is the TP2 but to check if hardware or software you may need to do a hardreset.

so many thanks for you interest in found a solution, but I already try that too,
I don't use windows, I use osx or linux, when I connected the phone to any so, always ask "active sync, disk or share internet", but now, nothing happen, only change the battery charge light.
this is very weird for me, I really care my phone, is my baby , is my business tool my partner, without it I can not work, I mean, I realy care it, never a fall, never a strike, I don't understand what happen
PS: anybody sell a TP2?

Sorry I couldnt help you out bro... I know wha you mean about these devices... i go thru withdrawl if i leave my phone at home just to run to the store... lol...
I have a tmo tp2 im using right now i looking to get rid of it only because im on att and cant use 3g with the tmo phone.
dont have n e pix yet but its in really good condition. i have it in the silicon case bought from tmo and selling it with a 2gb micro sd. my father had a warrenty exchange right b4 he gave it to me. shoot me a pm if ur interested

This same exact thing happened to me on my Touch Pro 1. It just stopped working. I even called to get RMA info, but never got around to sending it back.
Then suddenly one day, it started working again. I have no idea why. One thing that I did notice though was that the contacts seemed to not work so well... like, if I pushed the cable to one side or another, I could get it to make contact... but eventually it started working just fine without any issues.
It's still one of the world's most compelling mysteries. It will unfortunately never be solved, since I have switched to a TP2.

Same exact issue as mine. I had to return mine. The new one worked perfectly. The reason I think mine went out was a 3rd party charger. Did you happen to use a 3rd party charger to charge your phone?

USB not working. Going crazy. Ready to throw the Tilt 2 onto the ground.

I have no idea what's going on, but I can't get my Tilt 2 to tether, sync, or even see my PC. It was working fine one day, then it stoped working only to start working again. Today I spent over 4 hours trying to get it to work. I looked on all the forums to try to get help without any luck. I even hard booted (reset the firmware) and blew out everything in my phone. That didn't do anything other than to lose all my settings and configurations. Anytime I plug the USB cable into the phone (I've tried 2 computers and 3 different USB cables) it just charges the unit.
Would anyone have any ideas or tips I can use to get this darn phone tethering again or seeing my PC in general?
Thanks!
Nathan

Had the same happen to me. I had to use task29 to erase everything on my phone, then my computer recognized the phone as a storage device. I flashed a new ROM and ActiveSync worked again.

Yeap .. I Had This Happen ...
Had This Happen To Me to..
I had to bend the connector on the tp2 .. so the usb cable "fit" better

Ahah. I don't know. I never bothered figuring that part out. My Tilt 2 suddenly became very problematic, not connecting to the internet, or connecting via Active Sync, so I just used the program tool and task 29 and it worked out.

I just checked out the USB port on the phone. I got a pin that you would normally get when you buy new shirts and poked around in the port. I pulled out a bit of lint. Saw one gold pin was crossed in there and fixed it. Since it was on the bottom though it really didn't make much difference with tethering and such since a regular USB port seems to only use the top.
Plugged in the computer USB into the phone and nothing. Same thing. To think I started all this because first I need to sync my phone with Activesync and second I wanted to flash the ROM with the new AT&T ROM that's out. Doesn't seem I'll ever be able to do that. I think a call to AT&T is in order and maybe I can get a replacement unit. This one is really pointing to a hardware problem.

AT&T was no help whatsoever. They didn't even know what I was talking about when I said tether. Their suggestion since I didn't have insurance was to buy a new phone. Sigh. I saw that AT&T has the phone for 1 cent but I'd have to change my data plan to 2GB with tethering from my current plan of unlimited with tethering for the same price (damn Apple who made them do that).
Anyone have a suggestion on getting the phone I currently own to work? I'm not really inclined to buy software as someone mentioned (sktools). Someone mentioned replog.exe but they never specify if it's on the phone or the PC. Any ideas?
Thanks.

Silly question maybe, if so I am sorry but,
have you checked through the Active Sync settings on your phone and, if you have settings for the USB to PLC connection, check those. Also start up Active sync on your PC and check how that is set up.
Again, sorry if you have done this.

Seems to be a TP2/Tilt2 issue that's ongoing, the connector on the bottom of my touchpro2 stopped working as a USB connection a couple months back. Lately I've even been having trouble charging it in the car (since the cable bounces around). I'm using a non-stock ROM so I have to find a way to re-lock the phone (after re-flashing OEM ROM) without connecting to my computer.

Hi, not a silly question. I tried the phone on 4 different computers that had activesync on it and the phone wouldn't even recognize that a USB for data was plugged in. It worked fine for charging though.
I couldn't find any configuration for the USB port, so I may be SOL.

I was going to just buy a new Tilt 2, but thinking back the USB connector has been pretty flaky to begin with. Sometimes the unit will work when plugged in and sometimes I had problems. It could be that my phone was failing all this time and that's why it's been flaky, but others have had the same problem. Since I need tethering I might still buy a new HTC phone (I hate to do that since I'm not too thrilled with the way they design the phone) but just not the Tilt 2.

The phone hasn't been out for even a year, so you must have had it for less than a year. So its still on warranty, unless you bought a refurb. All ATT's phones are warrantied for one year. Refurbs are warrantied for 90 days.
http://telephones.att.com/telephones_ui/support/dsp_limited_warranty.cfm
Also, assuming you bought the Tilt2 at the subsidized price, you will not be eligible for the 1 cent discount price. You only get to purchase one phone "upgrade" at the subsidized price every 2 years. You will have to pay full price ($400) minus the $250 discount they have right now, so it would still cost you $150.
Try calling ATT again, it seems the rep you talked to didn't know much about smartphones or their company's data plans (since they didn't know what tethering was), or about their warranty policies.

Unless your phone is very different to my UK version it will have settings to allow it to use USB and maybe you should look further into the set-up on the phone itself.
The settings I have are in
Start/Settings/Connections/USB to PC.
Also,
if you run Active Sync on your phone and select Menu the connection needs setting there for USB.

Bluetooth
Have you try teether with Bluetooth? It is not a fix but at least this would be a work around plan. I can teether with Bluetooth or USB connection.

Thanks for all the help and suggestion everyone. They've been very helpful.
tjhawkes, I've been using the USB to PC for as long as I have had the phone. I guess that's what was meant when it was suggested I configure the USB?
chompx2 - I don't have have bluetooth on my desktop PC.
Redpoint - my phone was a refurb so I guess no warranty for me. I would be happy to pay $150 to get a new one though if that's what it cost. I tried to get the representative on the phone to do it but she refused(!) thinking I could get it cheaper somewhere else. I looked on ebay and everyone seemed to be selling it for $250. So, if $150 is what it cost, then I'm game for that.
That said, I have an old Tilt with a broken screen. I was going to take the USB port from that phone and install it on the Tilt 2 and see if perhaps that was the problem all along. I just looked at the USB port in my Tilt2 and one of the bottom row has a pin missing. Must have broken off. However, I can't imagine that being the problem though since a regular USB on a computer only uses the top row. Sigh. Technology.

Appears I was wrong about having to wait until your contract was up to get the 1 cent deal (check out posts 13 and 14 on the following thread):

I say go for it, since it sounds like you have a hardware issue (pins on USB port damages).

You will need to buy a phone that works on the AT&T high speed network. I don't think a "world" HTC phone will work with anything except EDGE.

I had the same no USB problem with my phone. Would charge fine via the cable, but no transfers, PC's wouldn't recognize it, etc, etc.
Took it into an AT&T store and they accepted it on the spot for a warranty exchange. They did the usual inspection for damage, water/moisture contact & such, but were happy to replace the phone for me.
I had a non-standard ROM on the phone, and changing the ROM and Hard-SPL back to stock via the MicroSD card was a bit of a challenge, but I did get it done in the end.
I was still able to sync via Bluetooth and use the Wifi Router on the phone for internet access for my PC, so overall, I would say that the lack of USB functionality wasn't a game ender for me, but I agree that it is annoying!
Cheers and good luck.

Because I like beating a dead horse with a stick, I thought I'd let you know what I ended up doing. I went to the AT&T store as suggested and they wouldn't exchange it. I called AT&T warranty and they wouldn't do it. The USB port's right audio pin got pushed into the phone so any type of USB damage would have ended up costing me over $300 for a new phone. I bought what I thought was the right port from a cellphone parts company in Hong Kong. Turned out the USB port was soldered onto the motherboard so I couldn't use the part. However, while the phone was open I pushed the pin back out and now the audio works again.
Syncing and tethering, however, is still dead. What's interesting was that it was working reliably, especially while on vacation just a week beforehand. Not sure what caused it to die.
So, I've basically given up. I fixed my old HTC Tilt (Kaiser) LCD screen and now I'm just going to tether with that phone instead. Sad because that phone is more reliable than the Tilt2. Too bad it didn't have the nice screen and a nice music interface.

Ouch, I had similar problems but with my Kaiser not my TP2 so I hope the same doesn't happen. I did some research and it turns out that the reason that micro USB connections are now the standard are that they have a much more reliable life cycle than the mini USB connectors the TP2 and Kaiser use (and lots of other Kaiser users complained of the same failure).
In brief, we're all doomed.

serious USB-port issues

Hello!
First things first: i already googled and search-functioned about 8 hours for solutions, tried them all and still got no luck so basically you girls and guys are my last hope. i hope my english isnt as rusty as i think it is. if i make any mistakes of any kind, please bear with them.
Used Hardware: Galaxy Nexus, the original Samsung OTG cable and the original Samsung charger
Software: Rooted, Bootloader-unlocked, stock-Android 4.0.4, 4.1.1 and 4.1.2
What is my problem?
as soon as i plug in the original charger it charges (duh!)
however, the moment i unplug it, the phone keeps thinking it is being charged. forever!
plugging in a original samsung USB cable without connecting it to something doesnt help, it still thinks of being charged.
but plugging in the original OTG cable stops the phone from thinking of being charged! (i dislike the thought of running around with a OTG dangling around the phone so that isnt a solution to me )
what happened before that incident?
bought on 15th December 2011
last software update 4.1.1 to 4.1.2 on 16.10.2012
worked perfectly until Yesterday
Recently i played around with the OTG cable and tried the following hardware to see wich works with my setup:
external HDD - NTFS formattet
PS3 Sixaxis controller
Corsair Flash Voyager USB3.0 Stick
AKAI MPK mini USB MIDI controller
Newest apps installed:
Sixaxis Compatibility Checker (18.10.2012 installed, used for half an hour and deinstalled)
Wolfram Alpha (17.10.2012 installed)
MyBoy (an GBA emulator - 12.9.2012 installed)
-latest ROM for that emulator downloaded on 13.9.2012
what did i try to fix the problem (in exact order)?
rebooting
changing the battery from 2000mAh (its an original, bought about half a year ago) to stock 1750mAh
removing the battery for 10 minutes
draining the battery to absolute zero and fully recharge it
carefully cleaning the microUSB port (with battery remover of course)
super carefully bending up the thounge-like part inside the microUSB port so that it doesnt get in contact with any surrounding metal parts (battery removed of course. when i say super carefully, i mean super duper carefully! i know how fragile those parts are!)
trying to hard reset the phone (that was a failure i just got from fastboot mode to a droid with a red triangle and an exclamation mark on its open stomach)
factory resetting the 4.1.2 via factory reset option (backup with Titanium Backup was made correctly but i forgot to copy it from droid to PC :silly: )
wiping the cache via fastboot
quick reflashing the 4.1.2 via fastboot
quick downgrading back from 4.1.2 to 4.1.1
quick downgrading back from 4.1.1 to 4.0.4
quick upgrading to 4.1.1 (it still is in that state)
complete reflashing the 4.1.1
- with reflashing bootloader
- with reflashing radio
- with reflashing recovery partition
now i am out of ideas
i think the USB port is seriously damaged. but since i am not so good with soldering and electronics i fear that i am not able to exchange that.
any more suggestions or ideas what might have been the cause?
next few days i will take it to the service center wich i really dislike to do because here where i live that means they keep it for about 6-9 weeks to fix it and i will not get a replacement in the meantime. anyhow my hopes are low that they might fix it i rather believe they replace it for a new one wich i also would dislike. Good thing i made a insurance for that device so in worst case i dont have to pay a single buck...
greetings everyone

Weird. Did you try flashing a stock Google 4.1.2 image? (Check out mskip's thread in Galaxy Nexus Android Development and download the toolkit - make sure it's compatible with 4.1.2 first)

Yes your USB port is most likely broken. Many others have had this problem including me.
Mine was so bad that my PC wouldn't recognize it and neither of my pogo pin docks would work.
I replaced the USB flex cable this week and it works great now. It was a relatively easy repair if you take your time and have the right tools.
The part only cost me $7. http://www.ebay.com/itm/190704059979

I had that same issue after my phone got wet. After about 2 weeks the issues with my USB port went away altogether.
You take your phone places where water might condense on/in it?

thanks miketoasty and thanks El Daddy! i really like this forum a lot very helpful people here.
i ordered the part. Estimatet shipping date somewhat between 30. october and 5. november.
will post updates
at least that error of mine doesnt drain extra battery
reuthermonkey:
i cant think of any place i visit frequently with high levels of moisture or with wet places. I am really careful about that because i love my Nexus witch even goes as far as never ever taking it into the bathroom (not even to a save and dry spot) while showering or bathing. Rain is a bit rare here and even if it is raining i wont leave the house without putting the phone inside a phone-pocket and into the inner side of my jacket.
greetings

I had the same issue as you. I ordered a new charging port cable for $7 on ebay, installed it in 15 minutes, and all is well in the world.

If anyone else is having issues, I have a spare USB flex cable that I can send you for just the price of shipping...most likely $3 or so.

Asus Zenfone 2 ZE551ML - very slow charging, not detected by PC.

I have two pieces of ZF2 ZE551ML at home. One is my and the other one belongs to my wife. My wife's phone had a broken mini USB port - the first 2 pins from the left were visible - the plastic had broken apart. Firstly, I did not relaise it could be the problem, luckily I managed to change the whole PCB including the broken USB port, however after this change the phone is not being detected by a PC, nor it is fast charging. As I have two phones at home, I checked performance with the other unit and unfortunately, the other one does quick charge and is detected by aPC, so it is not the cable, neither is it the missing software.
I bought another PCB and changed it as well, however still no joy. Does anyone have any brilliant idea how to fix it. I should also say that all other or most of the functions of the phone are working fine (at least those I managed to check: GPS, Wi-Fi, GSM+dual SIM, torch, bluetooth, and so on).
The only problem is that the phone loops on the SMMI Test #1 and is not going any further. I have also tried to detect phone by adb, still no joy. The phone is not rooted!
I have my personal suspects that it could be the faulty main board or a software bug. Any ideas how to fix it?
My phone is running LP 5.0, soft: LRX21V.WW-ASUS_Z00A-2.20.40.198_20160930_8756_user044030427_201501060109, kernel [email protected] #1 Fri Sept 30 15:31>23 CST 2016

Sdcard slot is working?
I would check the connections on both ends of the flex cable with the sim and sd slots on it.
I am having the same problems (because of the busted sd slot). I ordered a new flex cable. When it arrives (approx. 2 weeks) I'll know if that was the cause.

Yes, SD slot is working and both SIMs, so the phone itself works fine, only very long charging and is not detected by a PC.

Hi, I did changed both PCBs between phones. Firstly, I had the same problem on both phones, then I made better connections and the batteries started to warm up. Finally, the new one works with the other phone, the old one from the other phone still creates the problem. Probably, it is not the PCB then, or USB connection. It must be something else.
Anyone, any idea?

try fashing raw firmware
on motherboard you can inspect or clean the connector where pcb connects. use magnifying glass to inspect connector

Ok, I actually would like to flash the raw firmware, however I need some guidance here, as the phone that has a problem, is not rooted, and it cannot be detected by any PC now, so I am stuck in the middle and do not know how to proceed...

i am little confused here... you changed pcb on one mobile and fast charger do not works on that. you have other mobile which is working perfectly. both are same model.... if right!! do the following thing to find out...
Phone A:- changed PCB. no fast charge, not detected by pc.
Phone B:- working perfectly normal..
now we want to guess if pcb is faulty or there is issue with flex cable or any software related issue..
remove motherboard from phone A. and install it in Phone B.. if on Phone B. things works well then definitely its problem related to pcb.. if things don't works on phone B too. then it may be a firmware related problem..
raw cannot be installed without pc..... the thing you can ty is updating firmware from sd card via recovery mode.

That is correct, I say it again - I have two phones, same model, same software, kernel, etc. One had a damaged mini USB port, so I purchased 2 PCBs which have mini USB port souldered onto them. I bought them twice, as I was not sure if the first one I got was the correct one. Now, after your first message I changed the PCBs between phones and the result is the same, phone A (which is ok) works with the replacement PCB, and the PCB from working phone still does not work with phone B (the one that has a problem).
As a second step I replaced motherboards between phones now, and the result is still the same, meaning the motherboard from phone B does not seem to work better while it is in phone A body. The symptoms I'm struggling with are: charging takes over 8-9 hours, so it is considerably extended charging (battery is original factory battery 3000 mAh), the phone does not fastcharge at all and it is not detected by any PC.
The phone is not roooted so, I'm afraid I cannot make any changes to firmware through recovery, as it needs to be connected by a cable to a PC, unless there is something else I can do about it, but how to get any further?

which firmware you are currently on? lolipop or MM? factory reset your device then apply latest lolipop update from sd card

I was on lolipop, updated to MM now, but still no joy, charges very slowly like before and when connected to any PC it says one of the recently connected devices is not working properly, so I'm stuck ... I cannot root or apply any ADB sideloads ...

Is your ext. sd being seen in file manager ?
Can you get into 6.0 recovery ?
If yes , you can now downgrade which will reset your fone , With a factory reset in the process , check my signature below.
Your fone not being seen maybe driver issue if other zens too are not being seen...but ..let's see what happens after downgrade.
After downgrade if still slow charge, reboot while connected to charger.
If same prob ..hardware !

Thanks, I was not so deeply checking all available options. SD downgrading worked well for me, however the problem still is in the phone. However, I discovered a few positive and negative signs, which tell me that there is something else - could be the connection - after upgrading to MM before the phone was restarted at least 3-4 times the screen was not going to sleep mode after a minute, it was coming back on and on and on again. After 3-4 restarts it behaved normally again. The same thing happened after downgrade to L.
Another positive discovery is that the SMMI test now works well and everything is ok now, before it got stuck on the 1st or 2nd test and was not going any further ....
One more spot, which was very hard to catch as it popped up for a 0,1 second but dissappeared then quickly so I had to record it with the other phone and play very slowly on the PC - it looks like the Asus cover window pops up and it says - move your finger around the circle to get quick access to your preferable apps and there is also a blue button: Do not show again . This is flashing now and then and I do not have Asus Cover, so the behaviour is quite odd to me.
I have a feeling that there might be something with connections, but really I do not know what else - I checked it 30 times and made sure everything was properly alligned and tight when I was changing the PCB with micro USB port.
By the way the other phone works well on PCs, so I must have all drivers installed, it is just the second phone that is half bricked... I'm wondering now if maybe flashing CM 12 or 13 will help, however as it is not rooted probably it will not work via SD card... or? Am I looking in the right direction?

Buddy , its hardware so software tweaks will be useless .

Buddy, we are on the same ****ing boat.
I tried to go back to 6.0,but i got my phone bricked and now i cant reverse it back because i need usb connection to the computer and simply it isnt recognized.
I suggest you to send the phone to the asus assistance centre or to buy a new usb port for your phone,as it is clearly damaged like mine.I need to do it too so if you want to wait me first so i can check if it works,ill maybe save you some money.

Well, my phone successfully reversed to Lolipop, and I changed the USB port, I talked to Asus authorised service centre and they said it will cost the price of the phone, so I just give up, as everything works, but not the phone with the computer via USB and not the quick charging. Asus centre said it is a motherboard failure, but I'm asking how is that possible if all other functions work well???

Yes, I see your point, but I cannot imagine how is this possible, when all other things work well on the phone and the SMMI test shows all sensors working properly?

Ask yourself the same 2 questions again once more
Is your phone recognised by PC ?
Is fast charging working now ?
If answer is no after downgrade .
You know the answer

i changed mainboard and working
well, i have the same problem and i try the following possibility and all unsuccessful.
1. i tried 3 different pcb still no luck
2. i changed sim flex still no luck
3. i changed battery still no luck
4. i changed lcd and digitizer completely still no luck
5. i wiped cache from android recovery MM still no luck
6. i wiped data and factory reset from android recovery MM still no luck
7. i install same latest os (MM) for ze551ml from sd card still no luck
8. i use original ac adapter and cable and tried working different one for every step.
so i want to ask a questions. can it be ground connection somewhere on cases? or motherboard
i am tired but problem found. it is exactly motherboard problem. i bought used original mainboard and all is working.
Note: other mainboard using same android os version so it is not os failure.
