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

I've searched all over and have tried several "solutions" to fixing my activesync problem but, none worked. For a few weeks after no problems whatsoever, activesync no longer recognized my phone (T-Mobile Touch Pro 2 stock WM 6.5 ROM). I've tried changing all the settings on my phone, ie: checking/unchecking the box to enable faster data synchronization, checking/unchecking the box for synchronize all PCs using this connection and made sure it was set to USB. I've uninstalled and reinstalled ActiveSync 4.5 on my PC. I've Hard Reset my phone several times. All that and still my phone is not recognized, it only charges (using my phone as a disk drive for file transfer does not work either). I've installed the activesync.sa.cab and ran it, still no luck. I've used SKTools to recreate activesync. All this and still no luck.
Is there anything else someone has tried and has had success with? I would like to have some end to this frustration.

I don't really believe the issue is with activesync itself, but to prove that you can establish an activesync connection over a bluetooth connection, and I have a feeling it will work fine that way. I've seen this problem come up a lot, and there's been several occasions where it was only cleared up by having the USB port on the phone replaced. The ports still seemed to be ok for charging, but the data pins weren't working as they should. I've seen that reported on the TP2 frequently enough to believe that there might be some design deficiency there.
About two months ago my TP2 began to fail connecting and sometimes would connect but not sync. When it did connect and sync it would be very slow doing it. I messed with it for about two hours and it began working again, although it wasn't clear what I did to fix it, and was fine for another month. At that time it started failing again only this time I couldn't revive it even after lengthy tech talks with HTC and VZW. Since the phone was only a few months old VZW replaced it and the new one works fine.
I am having a very annoying issue with my Galaxy Nexus. When I connect it to my PC, it recognizes the device, however, constantly connects and disconnects. The USB cord is not moving. My other USB devices connect and stay connected (hard drives, mouse, printer, droid). I found this post attached, however, therre is no PhoneUtil code for the Galaxy Nexus.
Does anyone out there know how to solve this issue?

Have you tried another usb cable?
yes. same thing happened.
I have the same issue on 2 separate Galaxy Nexus phones now. no solution yet. I am on the phone with Samsung to see what they can do.
thanks for the reply. please keep me posted. i havent resolved my issue yet.
I've tried changing it from MTP to PTP and turning after switching between the two. I've tried two different roms, one based on 4.0.4 and 4.0.3. I've Tried several different USB cables, including the ones that came with my G2x and Nexus One. I've tried it in a USB 3.0 Port. I've tried using different kernals. Even when I get into recovery, windows still doesn't read somthing is attached. I've been transfering ROMS to it via dropbox. I don't think it's a rom issue as it should still show up in windows when in recovery. Also on those roms I made sure that they didn't have "USB Fast Charge" enabled, as I heard that can cause the issue I'm experience. Thinking it was an issue with CWM, I downgraded it, but still no USB. I'm stuck here. Any help is greatly appreciated.
The 1st posts pdf seems to be the most logical solution, we just need the phoneutil code for the galaxy nexus.
This seems to be a common issue with the GNex, see http://code.google.com/p/android/issues/detail?id=23789 and http://forum.xda-developers.com/showthread.php?t=1427539.
Please star/comment on the google issue tracker.
thanks for your post. the issue in the posts you included seem to be a different issue. those refer to the battery and charging icon, while my issue is related to the computer recognizing and connecting with the phone. i am going to post something on the google board though, i havent seen that one before. thanks!
It's the same issue...
Before I had the problem with the charging icon it started just like your problem...seems to be a problem with the usb plug....only solution is to send it to repair or exchange the phone.

What annoys me is that when I got the phone it was already rooted and I didn't have a chance to try it stock or back up the original. It was rooted with an older version, so I flashed 4.0.4 on it. Check out the reviews on newegg I'm not alone in reporting a messed with Galaxy Nexus.

I found a fix for the issue
This was a very frustrating issue for me. I just purchased the phone yesturday to have an issue like was unacceptable. After hours of frustration, I found a solution. First off, download the offical driver pack from samsungs website. Once you have the pack installed, plug the phone back in. Once you have completed this, go under development and enable USB debugging. After the debugging, you should have a stable USB connection and wired tethering will work. I hope this helps you guys with your issue. It resolved mine. This was also done running Windows 8 beta.
Hello all.
So I got my Note 7 last week and when I got it home I found that i had major issues with my home WiFi. Now I have a ton of devices ganging from laptops to TV' Phones and Tablets and none of them have any issues getting on the net via the WiFi. But for some reason my Note 7 is another story. The Firewall I run at home is a Sophos UTM 9 virtual appliance. I like it because it provides all the features I need and then some. I have already spent many hours tweaking, Tuning and trying to figure out why my Note simply does not want to play on my network. In order for me to have a reality check I installed and Untangle firewall appliance on my VMWare server and switched my firewall over to that. After making the switch my Note seems to work fine. Now if the Untangle firewall offered all the features I wanted in a firewall I would just say what the heck and stay with it however it is not as robust and does not fully meet my needs.
Has anyone else has similar issues with their Note 7 and if so have you been able to resolve them. I did post in the Sophos forums and so far only had one reply with someone having the same issue but has been unable to resolve it.
Many Thanks
Hi everyone,
I am a big fan of Samsung, especially, note series. I am using two devices same time included: Note 10+, Note 9. I updated software in both of them last week. Everything is ok so far but I encounter the big issues of cable to connect PC.
I can not use my original cable (type C to C) to connect my phone to PC. It had worked before the software updated. I tried to reinstall drivers or Samsung DEX but nothing changed so far. This problem happened not only in my Note 10+ but it also happened in my Note 9.
Besides, I tried with my USC 3.1 to C, USB 2.0 to C result in one of them work which is USB3.1 to C. It means the communication between Mobile and PC is operated via USB3.1 only. I try to find more information about these issues.
I really need your advice now, guys. Please give me some ideas or way I can fix this problem. Does also anyone have same problems with me??
Look at the error messages on the PC.
Clear the cache on the 10+'s boot menu.
Check all related settings on both machines.
If everything's running well and stable... I avoid updates.

Tks your advice. The problem is my PC didn't recognize my phone like it used to do. Nothing happened when I connect my phone to the PC via type C-type-C(USB 3.1 gen 2 to type C) or USB 2.0-TypeC. I used a USB viewer to check the connection, however, the result is negative. Otherwise, the connection works normally when I use USB 3.1 gen 1 to type C, USB viewer also can detect the connection from the phone.

I haven't played with this yet... as I expect the same fun you're having:laugh:
Bad or wrong cable or maybe a driver issue.
Maybe missing MS libraries (side by side errors is always that).
Use the MS Event viewer to see the errors.
Maybe reload the driver(s). The correct driver may be bundle in other Samsung PC apps you haven't installed.
Make sure the phone USB is correctly configured in Developer Options .

I tried all of your recommendations above, however, nothing works until now. I tried to contact supporters from Samsung and other Samsung android. I recognized the problem only happened in Exynos devices. Somebody in the Vietnamese forum had the same issues as me and his devices are also using Exynox.
So that anyone in this forum has experienced that problem please confirm in this forum for tracking. I figured out the technology inside this problem which is my phone can not use D+/D- from USB 2.0 anymore. I do not know that problem occurred due to Firmware or Hardware falures. Try to find something is useful, and recommendation from you guys. Thanks and have a nice day.

Nothing happened, I think somehow my note 10 plus D+/D- of USB were dead which result in PC can not detect the signal. I tried to use USB cable to test the resistor in D+/D-. The result is OL(in VOM). In my opinion, somehow firmware affects my D+/D- ports which cause the lost connection. I got it from the last update firmware from official Samsung. Before that, everything goes right, stable connection to pc, stable charge with the adapter.

Try a known good cable. Try another PC for clues of the root cause.
It could still be a setting or apk issue in the Samsung; of course it could be completely the firmware.
Even if the PC sees/doesn't see the connection being made it could still be a driver issue there.
Event Viewer has it's limits but was a good starting point. I had a similar issue with a PC USB driver and it was a real time consuming pain. After rolling back drivers multiple times and many reboots latter, it worked.
Keep googling and playing with it... you'll find it.
Once I have a fast,stable platform that's running well I rarely update.
Tired of MS, Android, Samsung, AT&T, etc screwing up my OS loads. Malware, Trojans, viruses, etc. have cost me one OS load max in 16 years even on very outdated OSs.
None on Android that required a reload... not one in 6+ years.
Of course it can happen but it's obvious that for me that most times updates/upgrades are the real malware:laugh:

I have the same problem on exynos note 10 plus 5g! Have solved yet?
Meh... Rule #1, if your Android OS is running fast, stable and fulfilling its mission, let it be.
My 10+ hasn't been updated in over a year and a half. Current OS load is over a year old still fast and very stable with little maintenance needed.
Security has not been an issue.
The easiest fix, now, would be to flash the firmware* that was working.
If that doesn't work the C port PCB may have failed. I would suspect that before a mobo failure.
*during production run Samsung will substitute chipsets as supply demands. This may lead to firmware updates being incompatible if the correct instruction set is omitted and/or incompatible for those chipset(s).
Yes this happens and worse Samsung has to physically examine the phone to determine precisely which chipset was used. Then Samsung engineers can hopefully rewrite the firmware to be compatible with all devices... or replace the chipset(s)

If you haven't done a factory reset, do so. It won't run right until you do. Do not use SmartSwitch.
