USB Device Not Recognised - A NEW APPROACH

I'm hoping the wisdom and expertise I always find on this forum can help me.
I have a new AT&T branded HTC Touch Pro 2 (Tilt 2). After about a week, I began getting the dreaded "USB Device Not Recognized" error any time I plug it in. It never connects properly. I have customized the phone using some of the cool tools I found here, but I have never flashed any portion of the device - it's just the way I got it (WM6.5 CE OS 5.2.21849 Build 21849.5.0.63)
As suggested in various places on this forum, I have:
Soft Reset the phone numerous times
Rebooted the computer (WinXP) many times
Tried several different cables, including the HTC branded extUSB one
Tried different USB ports on my computer(s)
Tried other computers (WinXP)
Tried Windows 7 (WMDC) on another computer
Hard Reset the phone several times (with and without backup restore)
Uninstalled and re-installed ActiveSync 4.5 and the USB drivers
Adjusted various settings, including USB to PC, according to various posts
Cursed extensively in three languages
Regardless of any of this, every time I connect, I get the "USB Device Not Recognized" error within a few seconds.
I am now convinced the problem is hardware, probably the USB connector on the phone. I can't be without the phone until later this month, so I can't get the hardware fixed for a while. But I need to sync.
USB, of course isn't the only way to sync; the phone has Bluetooth. The problem is, I previously reset the device and un/re-installed ActiveSync, removing the pairing at both ends. To sync over Bluetooth, I have to first sync over USB, something I can't do.
MY QUESTION IS THIS:
Does anyone know a way to force ActiveSync to pair over Bluetooth WITHOUT first pairing over USB?
Any assistance anyone can offer will be greatly appreciated

if u go to settings>connections>usb to pc un check enable faster data sync
that might help

Thanks for the reply. Unfortunately, that's one of the first things I tried and it makes no difference (I just tried it again - no joy). I should have listed it in my original post.
The only thing I can think of is to somehow force the phone to sync via Bluetooth WITHOUT having previously synced via USB.
Anyone know if this is possible and, if so, how to do it?

I think you should go and replace your hardware if it has warranty (since you have not flash it). tell them my phone USB connection is not working at all, and let them try it on their computers to make sure, am sure the warranty covers this kind of things

Uh, you're talking about the error on your PC right? This is a common issue. (with pc's) Use another USB port on the computer. That is what I have had to do. It worked fine for both the TP2 and my Wizard before that, but ever since I reloaded the computer I get that error on certain USB ports. have not researched it too heavily yet, but I plan to.

Did you try installing the Windows Mobile Device Center?

Did either of you read the post? It clearly states that he has done BOTH OF YOUR SUGGESTIONS!
Unfortunately, it does sound like this is an issue with bad hardware in the phone. I would suggest getting it replaced under warranty.

I'm having the same problem (vzw TP2). I've already messed with all usb-to-pc settings, tried different USB ports (I've had other USB devices that req'd that), reset my PC (thank you dogbert), reset my device and am currently reinstalling ActiveSync; though I doubt that's the problem because my BT syncs work fine (I don't recall being req'd to do a USB sync intially before doing a BT sync, so I can't really help the OP with that). My device does charge via the USB cable when plugged into the PC. Disk drive mode doesn't work any more than activesync. I also haven't been able to spot it on device manager. Uninstalling it there was one of my first ideas.
I'm wary of using a BT sync to install the official VZW 6.5 ROM, because I've read bad things about ROM interruptions.
I have yet to find by searching anyone who had a real USB sync problem (i.e., one that doesn't get "fixed" by resetting or something equally simple) who has actually posted that they found a solution.
@OP, when do you get a message that you are req'd to sync by USB first? Does activesync tell you or your device?

I have this problem at work where the machine is managed. It just refuses to recognize the device. It's a security issue that we haven't been able to track down yet. I think if you look in one of the logs (forget which) you will see the actual error as it tries to load the driver.

just for the hell of it, try an older version of activesync. just tryin to throw in all possible fixes. http://www.microsoft.com/downloads/...3a-28bf-4cac-a682-58d3233efb4c&DisplayLang=en
try removing the sdcard and syncing?

RE: A New Approach
Thanks for all your responses. Sorry to take so long to respond to your questions and suggestions, I've been away (funerals and CES).
I have read extensively on this subject, have tried EVERYTHING everyone has suggested, and reached the conclusion that this IS a hardware problem, probably involving the USB jack itself.
At least for a while, replacing the hardware is something I can't do.
I want a BT sync for syncing with Outlook (Calendar/Contacts) and for installing software. I currently have NO plans to flash the ROM, I agree that would be risky over BT.
The error appears to be generated by Windows, I don't think it ever gets as far as ActiveSync, ActiveSync always indicates that it is not connected.
Despite that, I did try an earlier version of ActiveSync (can't remember which one); no joy. I tried Windows Mobile Device Center on a Windows 7 machine, but the results were the same: Device Not Recognized.
SO, does anyone know how I can force a BT sync WITHOUT first syncing by USB? That would solve my immediate problem.

Unfortunately I been there and done that.
The only workaround is to use a free exchange server - www.alol.net.br
I put it on my computer's outlook. Copied all the contacts and calender items from my default folders. Synced with ALOL. Installed on my phone, and synced via my wifi.
Not the best solution, but T-Mobile refuse to fix the faulty Diamond motherboard, but it works fine.
The first sync on the phone comes up with a error message, but after that it is fine. You need to manually put in all the settings.

I'm assuming that you have your phone set to "Activesync" + Enable Faster data synchronization on your Phone, under Settings->Connections->USB to PC
Have you tried changing this to "Disk Drive"? Activesync can still connect to the phone and do syncs, etc.
Atleast this is my experience on XP. I've had the same problem on/off after flashing one particular custom ROM.. Don't remember seeing this on my stock Tilt2 ROM.

Have you tried turning your computer Windows' firewall competely off? I read soom were that there seems to be some confict with windows firewall reconizing Activesyc.

None of the settings in the phone, including Disk Drive, make any difference. I'm fairly certain that I've tried them all. None of the settings on the PC side, including Firewall, make any difference either.
The connection never gets to ActiveSync; the USB drivers fail to recognize the device well before that.
As I mentioned earlier, I have become convinced that this is a hardware problem with the phone, probably related to the USB connector. All my research leads there.
The approach I'd like to try is to bypass USB connectivity completely and attempt to sync over Bluetooth. The problem is that ActiveSync refuses to sync over Bluetooth until AFTER the first USB sync (and setup).
Thus my question:
Does anyone know a way to force a sync over Bluetooth WITHOUT first syncing over USB. Registry hack? Settings change? ANYTHING?

Quick note.
This issue started happening to me as well.
And here's the somewhat odd part. With the SD card removed the phone is discovered properly. The original SD card and another spare one inserted in the phone cause the this USB error for me.
Go figure.
(and yes I've tried formatting the sd cards, and factory resetting the phone)
Since I use ubuntu, I'm not really going to spend anymore time figuring out this windows bug. Just needed to apply an update..via windows.

Try this it worked for me

[Q] WMDC connection to Win 7 x64

I have a HTC Touch Pro 2 (US Cellular) and trying to connect via USB to Windows 7 Ultimate x64 OS. I have several times to install, uninstall, re-install and still no go. I found a few posting searching Google and nothing specific has help.
When plugging in cable, the phone is recharging. Unable to recognize or show up in Device Manager. I have successfully connect phone to PC by using Bluetooth but not able too at all with the USB cable. Tried several other cables and still same issues of not connecting.
I am sure it has something to do with drivers. however can't find any specific driver for the OS and Phone.
I have tried other combinations such as other USB ports, unchecking the box "Enable faster data synchronization" Reinstalling WMDC 6.1, uninstalling, rebooting, hard-reset, soft reset, etc.
So I am at the point of just throwing the phone across the room. I seem to recall about having problem another time and same issues, but was able to find solution. Unfortunately, not able to now. Please HELP!!
Please email me at <removed>

First, I edited your email out. That will surely get picked up by spambots, and you'll have a LOT of spam in your inbox.
Second, when you plug it in, you should see a popup on the phone in WinMo. Should give you a few choices, depending on ROM - choose "ActiveSync". If you don't get these choices, simply unplug-replug.
If you set it to "always" do something - like USB mass storage mode or something, you might have to modify the registry. I haven't used WinMo in so long, I don't even remember how to get it back to that menu which gives you the choices... I never check that box anyways, I always want to choose.

Thanks

It's on the phone.
Did you unplug/replug? If it doesn't pop up for me at first, I do this and it ALWAYS pops up...
UNLESS of course you've told it to "always" do something like USB mass storage - this is the piece I cannot remember how to setup...
What ROM are you on?

Go to the Settings Tab in HTC Sense and click on the right softkey and select All Settings. Then select Communications and select USB to PC and check the box that says ask me what I want to do when I connect.

[Q] Constantly rebooting on USB Mass Storage, CM7.2

Hi, my poor Gio is stuck constantly rebooting every time I enable USB Mass Storage. Debugging is enabled. I didn't have this problem before switching to CyangoGenMod 7.2, and come to think of it, I don't recall having this problem until recently.
This problem occurs on Windows 7 Home Premium (regular USB drivers, no KIES) and Ubuntu Linux 12.04 Precise Pangolin, both 32-bit.
I really wanted to add some files, mostly music and videos, to my device quickly, but as DoubleTwist (my main media app, I love the UI) doesn't develop software for Linux, I am forced to use USB, rather than Airsync. The fact that I can't seem to use USB without my phone rebooting doesn't help much.
Anybody have a suggestion? I'll try disabling debugging, or maybe downloading the Android Debug Bridge? I can't try it tonight, but that doesn't make any sense. Why would either of those be a factor in just simply connecting Mass Storage?
EDIT: I disabled USB Debugging, and, though it took a while for the USB storage Android to say that it was in use, it finally worked, without rebooting. Now to see if it'll work again, or if an app on the SD card was causing the problem. The thing is, I have zero free space on the, what, < 200 MB Gio users have? So, if it is indeed an app (or even my Crystal theme), that'll suck.
Stay tuned for future edits!

did u figure it out?.... i have the same problem in my Sony Ericsson X8... with custom ROM Ginger elite v2... 2.3.7 .....
it reboots after trying to connect usb mass storage when usb debugging is not enabled... after trying for some time, it reboots
& when debugging is enabled, the entire phone hangs .....!!
if u figured something out.... kindly let me know...

I can't remember if I figured it out, I know I must have but this was a long time ago, and I can no longer connect to USB anyway due to water damage. I should be getting a Windows Phone 8 relatively soon anyway so it's not worth fixing.

Glad to hear it. I did end up getting a new phone, but it wasn't WP8 - and because Samsung has some bakas on their development teams, it's actually worse for the storage situation. I also don't like how there is no longer USB Mass Storage; rather, you're stuck with either MTP or whatever cameras usually use. Both seem to be slower than a regular connection, Windows tells you that your device may not be able to open the pictures in your music folders, and the MTP app locks your phone down until it's finished syncing.
I almost miss my Gio.
Almost.

Help
I cannot enter Mass storage mode. It is getting rebooted and also takes away the wallpaper I've set.
My phone is rooted Micromax canvas 4 A210 with custom rom (lollipop themed). This problem started recently. I can recall I installed ADB and so may be conflict with the drivers etc. I've uninstalled the Google USB drivers which installs with ADB but still no help. I checked turning on and off USB Debugging, no help. I also tried changing the USB port, no help.
Further I use Link2SD app and after a clean install of custom rom, I checked options like 'Auto link' and 'External card' as default install location. Would there be some apps which should not be moved to External card? If yes, then what they are ?

Solved: Joying - Mirrorlink Stopped Working After Flash

Hey guys, I have searched high and low for a solution to this problem but have come up empty so far. I just got a joying head unit and everything, including the easy connected app, seemed to work without issue. I decided well since I had the headunit running next to my pc that I would flash Malaysk's custom rom before installing it. After that, I reinstalled the app from various sources including the oem app but none of them seem to allow me to connect my same exact devices anymore.
Why is this important for me? I had planned on controlling a tablet in the back seat for my son who is still to young to put on show without trouble. Essentially, this would allow me to never have to reach back there to help him out.
I have read, from joying, that it would no longer work after flashing new firmware but that seemed to not be the case from some things I had read here (please correct me if I am wrong on that). Tried different cables and ports but no luck. I did read that a license might need to be carried over but not sure what that entails as I can find ZERO info on this easy connected app/problem. I hope that this is a very simple fix and that I did not jump the gun again for the chance to flash a new device (its addicting and I blame XDA for my problems...).
I did try and find some other apps that might allow me to do the same thing. RemoDroid seemed promising but didn't function. Most other ones are meant for controlling from a pc or browser and just weren't useful for the task at hand. I am open to solid suggestions. I use all Android devices and avoid the Apple juice. Any insight you guys can offer will help a tired Dad out. Thanks!
Edit: Solved-ish
The easy connect app seems to function now intermittently. Not sure there was a specific thing that I did to fix it. Seems to work when I launch easy connect app right after booting up and nothing else. Messing with other apps seems to cause a problem for my devices. Also, switching between my devices(phone and tablet) may also have been causing a problem, not sure yet. I suppose I'll just keep trying to make it work reliably until I break it again.
On the previous version of the easy connect app, you were able to disable Drive Mode from launching. Not so on the newer version with Android WiFi. If anyone has a solution to that I would appreciate it as the Drive Mode app is useless for my needs.
Note 4 - USB - works great. I have yet to try over wifi
Note 10.1 N8013(lollipop rom) - USB/Wifi - works great (disable smooth mode, remote device screen cannot be turned on with easy connect "Home" button)

http://forum.xda-developers.com/and...1024x600-rk3188-joying-try-uploading-t3262030

I tried several different apk's but they all have similar results and end with a connection failure.
I haven't yet tried going back to stock firmware so that might be worth trying. I installed the headunit in my car so I'm not as willing to keep flashin it as I have to park down the street from my house.

So not sure what magic I used but I was able to get it working for a moment and then it stopped again. USB and Wifi android mirroring were working so I know my current firmware/setup is functional!! Once I got it working I started configuring some other apps and when I went to run it again it wasn't connecting. I guess I'll just keep messing with it until I can figure out what got it working again.
With the newer version of the easy connected app, I can no longer disable launching of drive mode on connect. Is there a way to disable that option with the 1.4 version?

Hi.
Is it possible mirror in wifi with android?
Can you explain the way?

File transfer mode NOT media device mode?

Sorry for a kinda double post, as ive posted this in the noob thread, but I think its being overlooked.
When connecting to a PC, how can I get a normal file transfer mode?? the media mode is just too limiting, one file at a time, transfer with no ETA, cannot browse picture folders with image viewers.. "this file cannot be played are you sure you want to copy it" blah blah blah...
I'm sure on my old HTC sensation as well as media mode you had file mode.. but I cannot find it and I don't have usb 3.1 on my laptop only 3.0 so hopefully that's not the answer..
please help.. mostly after getting at my SD card without removing it from the phone as I can never find the "proddy thing".. not fussed if I need to install a third party app or other... but currently on stock EU rom non-rooted.

When connecting to a PC it should pop up a question about how you want to use the connection. So select Filetransfer and trust it with "Yes". And that s it basically. You can also find this in the notification bar... eh about what to use USB for.
Also be sure to have suiting drivers. IIRC they should be installed with HTC Sync Manager. Maybe installing HTC Sync Manager would fix your issues already?

How old? I think this special mode you refer to was removed some Android releases ago already. Nowadays theres MTP. By all this speed of that USB ports nowadays intention seems to be initially that you do not have to unmount it in order to get all that stuffs you knew from past. I remember when my ONE-S got a update suddenly in past where exactly this step to MTP happened. Since the USB2 hardware in this old phone was a bit older and worse it became slower than before. Many ppl had been looking for a fix for this, since you could not enable it like it was before. IIRC one solution was to use a custom ROM. I can not recommend using a custom ROM personally.

No it is not. I m also having a 3.0. Still at least with marshmellow you would have to enable the fast file transfer with 3.1 explicitly in the case you really have such port on your Computer. And still theres some influences and things to consider to get optimum bandwidth.
But a 3.0 connection is usually not as crappy as you describe it now. So i would sugguest you:
- I assume a driver bad.
- Or Faulty cable.
- Maybe some setting in your file browser on the computer?
- Is the preview disabled maybe?
- Latest drivers for the phone? (HTC Sync Manager)
At very first i would try to get latest HTC Sync Manager for HTC10 from HTC website. Or if you are in linux, check your packages, udev rules and that MTP gets rolling.
Hope this helps a bit.
PS.: Try connect your Phone to another computer with maybe Windows 10 and latest HTC Sync Manager. Just to exclude that your computer or its software might cause this issue.

Thanks for the reply, my "old" htc was probably 6+years ago.. I think it was my first android phone, Recently I have been using LG G3 running cyanogenmod, so have always had a proper "file mode".. it was just like plugging in an external hard drive. I did not realise this was not a feature anymore in standard android.
The main problem I dislike is not being able to view pictures... If I open one picture from my phone or SDcard, then my picture browswer says viewing picture 1/1 even if the folder has 200 pictures in it, I cannot space/tab through the pictures, I have to close that one, then open the next.... I do find it frustrating only being able to copy one file at a time, and constantly having to tell it that I do want to copy the file despite not being able to play it, but those things I can live with.
I already have tried installing extra software and on windows 7, (I am running W10) but no luck
It just sounds like they want you to remove the SD card.. shame they make it so impossible to do.. I'll continue to hunt for a solution without custom rom.. and post any findings.

How is it. How do you think about an alternative way to transfer data like e.g. from playstore Air Droid using WLAN.
Did you try another data cable, by all ports and operating systems?
And just in case. Do both of your computers feature the same USB drivers and hub? Maybe a driver issue.
I noticed one thing recently. When i connect with MTP and copy lets say: "400 MB pictures" taken with my old phone, spread on 97 files to the SD card it does not take long. But what takes long like 20 seconds after copying is done is that it shows previews. I have to really wait until it is done transferring.
So could it be maybe the case your phone does not finish somehow?
And yes the Windows Photo thingie does not see it as folder to slide through.
Meaning: i can not deny your issues fully.
Honestly what i totally love is an Plasma Desktop for linux is an software which called KDE Connect. You get WLAN connection to your phone and can even control the mouse. Do simple file transfers. And what i totally love about it is, is that it almost seemingless integrates into the Desktop. On the other End i think WIN10 does not feature such service (stock). Air Droid is one of those tools in this way which you can expand the computer expirience with. The preview and copying over WLAN is blazing fast. Plus you do not have to connect the cable.
But it requires a client/server and permissions on both ends. And thats what i dislike about the Windows side. It is not so seemless. And it is in the way of one of those extra services, running.
Also the speed of the SD card does in fact matter. Is it maybe one of the older generations you inserted?
The new SD's from this year are much faster and bigger.
E.g. read about SD card speed classes SDXC class U1, U2 and U3
Even if you can push 1 GiB /s through a cable.... if the SD only takes 96 mib/s...... lol
Maybe interesting to have a look at what about capacity / price is happening in 6 years.
http://www.anandtech.com/show/10315/market-views-hdd-shipments-down-q1-2016/3
So lets say you was using a 6 years old SD.
Your phone is worth (lets say 600 $) but the SD is not worth any cent. In case the SD was so old.

This is how Android now is.
What you're looking for is USB Mass Storage mode. They removed that because it was a wide security hole where someone could just plug your phone into a computer and copy all your storage and mess things up at will. Media Transfer Protocol (MTP) is all Android has now. Your phone memory doesn't just have your photos and music on it; it also has your apps, logins, systems files, etc.
The "file cannot be played" prompt that bothers you can be disabled in Windows. Just do a Google search on that. As for transfer speed, I'll bet you that it's a bad cable and nothing more. MTP isn't slower than UMS.
Good luck.

Thanks also.
I didn't mean to imply it's slow transfer. By limiting I mean it's holding me back. I like to transferr a 20GB video, and while it's doing it, go to my pics and view+sort them etc. But now I cannot. One at a time. Zzzzz..
It sounds like I will either need to investigate lineage again. (I'm unsure at this stage what I loose if I do, camera apps, mirror cast etc). Or perhaps buy a hand full of "proddy things" so I can more easily remove the SD card. I can never find it when I need it.
Thanks for helping me get my head around this alien tech/systems. I feel I understand now what's happening and why.
