[info] USB Connection errors - Captivate Q&A, Help & Troubleshooting

Solution: Try different USB ports (all if necessary). Yes, this seems like a silly oversimplified answer but it is a common problem.
Maybe it's because the Cappy is old and the recessed port makes fully seating the micro USB cable difficult. I whittle away the plastic around the cable's connector to make sure it seats fully without obstruction. Even then, it creates a 'long-neck' connection that tends to have side-to-side play. Over time, with daily use, and bouncing around the car, the port on the phone can warp and cause a loose fit. I've tweaked the metal around the port to tighten it up a bit, but you have to very careful not to damage it.
A combination of the quirky port on the phone and your PC system can cause USB connection errors that seem to defy logic. Once it causes an error, nothing seems to resolve it; rebooting, clearing Windows log files, wiping and reinstalling drivers, etc., did not work. 'But I can connect an LG L5 that uses the same type MTP connection and it will work just fine?' So using this rational, I spent countless hours flashing the phone and working the forums. I'd been through similar circumstances enough times I should have known better, but I inevitably gave up and just switched USB ports on the PC and viola!
Your desktop or laptop typically has a set of board soldered USB ports (rear panel), and form factor wired USB ports (front panel). I don't know if it's a Windows thing that is not an issue with Linux, or a system firmware issue, I have had unrelated USB issues running Linux on my PC as well. But at some point the error mysteriously goes away and the connection will work again, possibly after disconnecting all USB devices and letting the system reinitialize them at boot? Since I'm on a laptop that frequently has different USB configuration, I'm not sure what actually fixes the problem.

I know the pain!

Installing w/2.3 multi-instaler and bricked my 8125!

Is there nothing to be done? I had a phone whose touch screen was acting a little off. I used Cingular_Custom_AKU2.3_Combo_Installer_V1 after unlocking the device and it ran fine. When the OS first comes up it requires you to recalibrate your pointer tho, and since my touch screen was fouling up, I couldn't. I called Cingular and got a replacement phone this morning. I turned it on and let it load up its OS. I used ActiveSync and had a successful sync. I unlocked the device. I used Cingular_Custom_AKU2.3_Combo_Installer_V1 again to upgrade the OS. At 40% my computer unexpectedly rebooted. According to the messages that appeared when the computer came back up it was a driver error that caused the reboot (http://oca.microsoft.com/en/response.aspx?SGD=aa971456-440a-4269-a79e-1f07bda35989&SID=10). I tried to run the installer again but it could not find the phone; ActiveSync could not be engaged. I powered the phone off and back on and just get the RGB screen. I tried to reset the device but nothing still. Am I completely screwed??
Do a little reading on interrupted rom flashes. Search for "Bootloader Mode".
You need to flash your device again but this time you have to start in the Bootloader screen (RGB Bars).
Cool thanx. I looked around for people having problems installing ROMs but the only thread I found no one had answered. This gives me something to search for. Appreciate it!

One other tip, from what I've read, it is recommended to make sure your Wizard is connected to one of the MAIN USB ports on your computer, for desktops, these will be on the back of the computer (the ones soldered directly to the motherboard). The ones on the front are usually essentially connected to a USB hub, and not directly to the controller.
On a laptop, all of the ports should be good.
mine did the same thing last night with the 2.3 with cf2. i had chosen option 2 (no bootloader) and my machine rebooted at 40%. Since this has happened to me once or twice before, i walked in the other room and did the upgrade from the laptop without issue. then sync'd the phone back up with my desktop as was good to go.
On a side note, you don't need activesync installed to upgrade the phone. if you keep running into issues try from a different computer. thats what has worked for me.

Seconded. Use the USB ports on the back of the machine that are directly connected to the motherboard. Sometimes the ones on the front are connected to the motherboard via a cheap connection.
A number of manufacturers assume users will insert and remove devices which scrapes off the oxidation, and use cheaper metal because of this. A connection that stays in for a long time eventually builds a large enough oxide "crust" it causes problems with the electricial connection, and becomes flaky. This is possibly why a number of front-port USB plugs become intermittant after a while.
I've noticed newer PCs are using gold-plated contacts which tend to make this problem go away, but both mating contacts must be gold, else you get bi-metallic chemical reactions between them, and have the same problem as tin or copper-based contacts.
Sometimes there are so many things hanging off a computer's USB bus that you might just buy a PCI card with USB 2.0 plugs on it and use that.

usb not working (only charging and headphones)

After the positive things after getting my kaiser back from repair I also noticed a huge problem....
I can't connect via USB to my laptop. If I plug in my device it starts charging and thats all, headphones works fine also... anyone a idea, below things i've done already..
-soft reset
-turn on/off advanced network functions
-tried different cables
-reinstall usb drivers on Laptop (vista)
-tried another computer (XP 2x)
-hard resetted the device
-do all the steps over again
I'm not planning to send it in for repair again... since I live in norway at the moment (normally in NL) I already lost it for 2 months...
Anyone a good idea?
cheers
Well you said it isn't working on vista, so I am willing to bet this may not work for XP. Check to make sure that you have the USB option in Active Sync checked. Other than that, I dunno. My USB port on the phone has been destroyed, I can barely connect to Active sync, but I am still able to charge. Stinking cheap plastic connector came out, tried to superglue it back, continue to come out, now the two pins on the right are busted.

Activesync Problem (Tytn2)

When i connect my device to usb, nothing happens.
I looked up the forum for solutions, but was unable to find them.
It shows nothing in network connections, nothing in device manager, en activesyc shows nothing at all.
I tried the following:
- Other USB cable/port
- Reinstall activesync or use older version.
- Uncheked advanced networking in my device.
- Turned off firewall
I cant think of any other solutions at this time, maybe someone can help me.
(sorry for my bad English, i'm Dutch)
Ciao,
did you try to remove your older connection from your telephone? I mean programs -> system tools -> activesync -> menu -> options -> delete existing connections.
This works for me whenever i have some connection problems.
No luck =(
Still the same
No one has any idea?
Reboot the PC. Make sure you check Device Manager for any issues. Maybe disconnect all USB peripherals and then try the phone first. Did you try a different machine (PC)?

What is the operating system of your pc´s
Windows XP sp3???
If so there are some issues that relates to sp3 but i dont know any resolution for it thou.
Nope, fully updated SP2
The HTC proprietary extUSB connector on the bottom of the TyTN II has been known to fail in a few cases (if you search in this forum there are many posts about it). When you plug in the charger or wired headphones do these work fully? Does your battery charge when connected to a PCs USB port? Not that these are 100% foolproof tests because different pins are used for the USB signal connection. What changes did you make or incidents occurred before this problem occurred e.g. started using a different charging cradle etc? Have you inspected the connector for damage and tried the original HTC cable?

The battery still charges via USB (via my pc), i used a charger in my car.
This is a USBport in the car, difficult to explain.

I can't tell you of my headphone works, because i lost it.
I can't dectect any damage to my USB port.
Update:
I've been looking at my USB port on mt PDA, and did a little bending, now when i connect my device, the screen flips to horizontal view.
So i guess the problem has to do with the USB connector after all.
Upd: OMG :O it keeps flipping from horizontal to vertical, even when it's not plugged in.

Be careful about using just any old car charger system. If you search this forum you'll see that there was one model which could damage the TyTN II due to overloading the UBS port on it (something to do with reverse flow under periods of heavy electrical load). I believe that model was subsequently modified to prevent this problem but it doesn't mean other car chargers with the same affliction wont arrive on the scene. Maybe it's time to hard reset the device and if it still plays up, return it to the supplier for a warranty claim.

USB Connection

Hey there
My phone has been connecting perfectly fine since I got it about a year ago right up to a couple of days ago.
I've just changed my contract and wanted to unlock the phone. However, before I could even go about doing I discovered that my computer (Vista 32bit) was no longer recognising the phone.
When I plug it in it does charge but the computer gives no reaction. Even when I put the Kaiser into bootloader it still says Serial instead of USB.
I have tried disabling enhanced network functionalities on the phone, I have reinstalled Windows Mobile Device Center, I have hard reset the Kaiser, I have used multiple USB cables and multiple USB ports (all of which work with other devices).
As a result of the hard reset I have now lost the majority of my data. It's all backed up on my computer but this isn't much use when it refuses to recognise the phone!
What can I do to fix this?
Any help would be very gratefully accepted!
Cheers
McAsh
I would try it on a friends XP machine or a friends Vista machine. Try to narrow down if it is the phone or your PC , and then proceed from there.
HI!
I have the same right problem!
The only way i can do activesync is connecting the phone in activesync by bluetooth and the sincronization is fine, but i need to put HardSPL in it and i need that it can be recognized by USB connection and my Kaiser is only charging from USB, it is not being detected by the computer.
PLEASE HELP!!!
Thanks!
had same problem
no one help, I started a thread and no replies
till today I plugged my kaiser to usb and computer recognized and synced
I was using bluetooth to sync for a couple of months
I really didn't do anything to fix this first I thought it was usb connection but it wasn't because I was able to put new rom thru the usb so connetctoin was there when the phone is in the hard reset mode. WEIRD ha
mostly these things comes down to 3 reasons
1. defect usb connector in the ppc
2. corrupt activesync install full uninstall and clearing registry of the pc should fix that
3. issue with usb port chipset drivers for on the pc
Also having a similar problem.
My computer recognizes my Kaiser as "HTC USB Sync" in the Device manager but nothing more happends. Could it yet be the phone USB connector that is broken? Also I was able to flash the rom yesterday (from bootloader).
When plugged in, my phone totally freezes and becomes available again the moment I unplug it and by then starts "connecting to host".
If I uncheck the "allow usb connections" box in WMDC the phone is workable but very juddery.
Have tried to completely uninstall WMDC and reinstall it again with no success whatsoever.
Any tips or is my only solution to buy a bluetooth-dongle?
The solution for mine is really the repair center unfortunately!
It really seems to be a hardware problem in the USB connector, i can't even change a firmware, the pda simple isn't recognized by the computer :S
Anyway thanks for the help!
Regards!
I am also having the same problem!! My question is how do you use bluetooth to sync with the activesync(not too computer saavy!!)
Check the usb connection on the phone. It may have a contact pushed over or broken
I got the same sympton.
I can get my phone to sync by pushing the USB connector harder towards the phone. Yes, it is connected already, and it is not lose, and the PC recognise it as HTC device in Device Manager, but it is just not detected by the (Vista) Windows Mobile Device Center
If I keep pushing the usb connector in (towards the phone), then it would get detected and start syncing. If I relax my hand and stop pushing, the active sync connection will drop immediately (still detected as HTC USB device in Device manager though).
Therefore, I have to keep pushing it in to have a successful sync. I don't dare to flash the firmware anymore... :-(
P.S. I am using the official O2 WM6.1 firmware, and using the original USB sync cable. I noticed that the original USB cable's connector head is a bit longer than ALL my other USB cable's connector head (the mini USB head).
Originally I didn't need to do the push in for the phone to get recongised, so I figure it is some sort of wear and tear on the phone's connector... :-( This does put me off in purchasing another HTC phone, because the new one is likely to suffer from the same wear and tear...
btw, before the connector got that bad, when it was connected but not synchronising, I could get it to sync just by launching Windows mobile device center (which is a different program than sync center in vista); and of course, when it was all brand new, I just need to connect the phone to the PC via the USB cable, and everything happened automatically...
I am trying to flash my first rom and the computer would not detect the phone. Took a look at the female mini USB socket on the phone and the 3rd pin out of 5 was much lower. Took a tiny screw driver and pushed it up and I got success. Its a little sensitive but if you dont touch the phone it will work fine.
Good luck
Jason
HI gdarrenc!
The way to sync it via Bluetooth is when you open the activesync in your pda, in the options menu you have the option to sync via bluetooth
Regards!
possible solution if feeling brave
My hotsync failed a few days ago, did the usual searches and posting on here with no joy and then did a google search for a picture of the mini usbport.
on inspection of mine in comparison i noticed the two leftmost pins were down to the point they were in the sticky out black bit so with a pair of my wifes best precision tweazers i flexed the black bit down slightly and slid the tweazers to the right lifting them up slightly. as soon as retested it is now working again.
NOTE BE VERY VERY GENTLE WHEN DOING THIS - DO NOT USE ANY FORCE
my guess is this is due to an ill fitting usb cable as mine had a certain degree of up and down flex when connected.
hope this helps someone.
I am also having issues with pc-htc connection.
But, this happened when I pulled the usb out of the phone with my leg.
Now, I squezzed usb head a little, and it works fine.

[Q] What to do when I can't see my HTC One in Device Manager?

Like in the topic. My pc can't seem to notice my HTC one phone. Not at all.
Some details:
PC - Laptop Lenovo Y580
Operating system - Windows 8.1 64 bit
Android - 5.0.2 I think (Lollipop)
My phone notices the cable (asks for internet tethering etc.) but I don't see it anywhere in pc's Device Manager (neither does HTC Sync Manager).
I've tried numerous things. I installed HTC Sync Manager, I've installed HTC drivers separately, reinstalled generic USB driver and drivers for USB 3.0, changed cable, changed port to another USB 2.0, change to USB 3.0, checked if it works on friend's pc (nope), reinstalled almost any of above mentioned things witt antivirus disabled, with firewall disabled, with almost anything that can be disabled. Nothing. It's not that case of wrong driver. My pc don't see this phone at all.
To be honest I'm tired. Like really tired. I've spent all free time I could find last week trying to somehow make it work. With no effect whatsoever. I don't see even slice of progress (noticing SOMETHING in device manager would be nice). I would love to see some way to analise this. I'm getting closer and closer to just buying new phone. Even though I don't want one, but I can't do any testing with this device.
EDIT: Few things I've remembered about my tries: I've tried both USB debugging on and off, and I've also already done factor reset of the phone - to no effect obviously.
When connected to pc, phone can be charged, but PC doesn't react in any way (no "USB connected", popping up HTC Sync Manager or "Media device connected" info).
I'll appreciate any help. Especially if it manages to change something in my situation.
Best regards,
Hisuu

When you plug in your phone to the computer do you get the following:
USB Connected
HTC Sync Manager
Media device [MTP] connected
Can you charge your phone while connected to the computer or do you have to use the wall charger to charge your phone? If you don't see the programs listed above, it sounds like a hardware issue with the USB port on your phone.

Yes, I can charge phone when connected to PC.
And as I mentioned phone actually notices it's connected to something, and asks what mode to enter (USB tethering, smart network sharing etc.). But it also seems... kinda dodgy. Sometimes phone doesn't react, I have to reconnect or even restart it. Sometimes "USB connected, Tap to change settings" stays... even after I have already disconnected it .
Few things I've remembered about my tries: I've tried both USB debugging on and off, and I've also already done factor reset of the phone - to no effect obviously. (I'll add this info to 1st post to gather info in one place).
Any other ideas?
This topic is my last resort, because I'm out of ideas and start leaning to buying new phone just for testing purposes (either Samsung Galaxy S3 or Nexus4 I guess).

start from scratch: Uninstall HTC sync and all the drivers you have tried. Then install HTC drivers only (not the generic drivers) or install HTC sync and uninstall it but keep the drivers installed (the idea is to have the driver installed but not HTC Sync, we don't want Sync to interact with the phone).
Try another USB cable but make sure its Data enabled (not only a charging cable). Some cheap cables are for charging only, no data connection.
Try another USB port, use 2.0 usb ports, do not use any external usb hub, use th eport directly on your motherboard (at the back of your computer).
Try with another computer
Clean your phone usb port using a cotton swab with some isotropic alcohol and then apply (spray) a light coat of electrical enhancer on your usb port (see your local electronic supplier or even some hardware stores)

Tried other cables (data enabled, they were from different phones), as well as different USB ports (both 2.0 and 3.0). Also tried another pc (no luck).
Uninstalled HTC Sync and drivers so many times I can't count it ;]
I'll try to clean the port and maybe use motherboard on friend's pc (on his machine I've only used front panel). Hopefully something works. Thanks for your input, I appreciate it.
