[Q] EVO Unrecognized - WTF??

Guys, I need a little help here. I've rooted my share of phones, and even some tablets, but the Evo i bought a few days ago has been a nightmare.
For some reason, and I can't tell why, this thing will not be recognized by Windows.
It always shows up as "Unknown Device" under the USB catagory on Device Manager.
I've tried different OS versions (Windows 7 64Bit, Vista 64bit, Even Mac). I've also pulled down every form of driver I can think of (SDK Orginal version, HTC Sync, Hboot Versions, etc.)
I just cannot get this thing to be recognized. And if I manually try to update the driver and point it to one that I've downloaded, Windows tells me that the most current driver is already installed.
The bottom line is that I need to be able to connect to the phone from the comp in order to push stuff via ADB and throw commands at it. The same unknown device situation happens when the phone is in bootloader or actually booted into Stock Froyo (2.2)
Has anyone ever seen anything like this? I know i haven't, and it's buggin me out.

I've never seen that before. Wish I had something for ya. Is the Evo brand new or used? Are you sure the usb cable is good? I've seen a bad cable cause some headaches before. Wish I had more for ya, sorry man.
Sent from my PC36100 using XDA App

EVO is not new. I bough it from cragslist a few days ago. It seems to work fine otherwise. Not rooted for sure, and running Sprint original 2.2.
I did try a couple of different USB cables just to be sure, and had the same results.
The funny thing is that even though I was never able to get it "recognized" on any of my machines, I was able to get ADB so "see" it for a while. I started the rooting process by pushing files to it via ADB and even sent a reboot command to it.
Once it rebooted, that's when it all went bad. It was still showing as unrecognized (just like before), but now ADB can't see it at all. Keeps telling me no devices are connected.
Even my friend's Mac Air (which supposedly doesn't need any kind of drivers to see the phone) can't see it either.
It's just weird...

perform a hard reset, maybe a rogue app or setting got messed up,
fastboot screen>clear storage>yes

Tried that as well. Sorry i didn't mention it in the original post.
I think I've pretty much tried everything that's somewhat logical at this point.
Now I'm looking for the "illogical" ideas.

Make sure usb debugging option is turned on in settings>applications>development and the phone is in charge only mode. Then it should be recognized and you should be able to use adb.

Debugging was turned on already. I made sure of that.
As for the mode of connection I've tried them all with mixed results.
Here's what I've seen so far...
Charge only - unrecognized device in Device manager, and ADB can't see it.
HTC sync - unrecognized device in Device manager, and ADB can't see it.
Disk Drive - unrecognized device in Device manager, and ADB can't see it.
Internet Sharing - never tried it.
Here's the weird part. If i uncheck Debugging and set the phone to HTC Sync, I am sometimes able to get ADB to see it.
This is just confusing...

What happens if you uninstall HTC Sync and just leave the drivers installed? Could work I suppose. I know unrevoked says to make sure you uninstall HTC Sync and install the ADB drivers.

try this. connect your evo to a machine running xp. i had the same problems rooting one evo using windows 7. connected to a machine running xp ,zipped right through without a hitch.
HOPE THIS HELPS YOU IN YOUR QUEST

Thats what I tried on the Vista box.removed HTC sync, and left the HTC drivers.when that failed I removed the drivers too and replaced them with several different ones I found online.none seemed to work.
The strangest part is that all guides seem to say that MAC OS should just see it without any drivers.
I borrowed friends MAC air and it didn't see it either.

I'm not sure which USB drivers you are using, but these work for me. Uninstall the drivers first, then install this. I hope it is legal to put these here and if not I am extremely sorry.
PS you could try a Linux Live CD and it will see it without drivers or go with Wubi which installs Ubuntu on your Windows hard drive and can be uninstalled just like any other program. It gives you the option to boot into Ubuntu or Windows on bootup. Neat little program and it is faster than using the live CD. Go to this link Wubi and click the Start Download button to download Wubi.

Those seem to be the same drivers I've tried (well those and a ton of others as well).
I'm gonna give that LiveCD idea a shot. Burning it now.
If not, I'm gonna try to find an XP machine somewhere.
I've got a couple of VM's on my machine running XP, but since the main Win7 Machine doesn't see it, it can't seem to pass the USB connection over to the XP VM.
Man, I have to say, this is just the most complicated rooting process I've ever seen. If this was my first root attempt, I'm pretty sure I'd leave Android forever

It usually is a painless operation to root the Evo. For some reason you are having a difficult time with driver installation. It seriously has to be something simple that has been missed, because I have rooted mine and several friends Evo's and it was very easy. I had a MyTouch 3g 3.5mm before this Evo and talk about a pain. Before the Universal Auto root app you had to make a gold card first and that in itself took over an hour. It was my first root and it was very difficult and time consuming, so to see how easy the Evo was no matter which way I do it made me very happy.

yes the mac doesn't require additonal drivers to run adb however u need to make sure the directory is properly set in terminal so adb knows where to pull commands from... on windows did u try uninstalling everything phone related? SDK, HTC Sync, the whole nine yards then try reinstalling only the sdk and the usb drivers? I know with the lastest SDK the usb driver is not included for some reason or at least it wasn't with mine... then one day my adb just randomly stopped working and a uninstall/reinstall cleared up everything... try this usb driver and see where it gets u. Don't know if it's any different that wat the guy above posted but worth a shot. Reinstall the appropriate SDK first then i would recommend plugging the evo into the pc with no usb drivers installed then when it cant automatically find the drivers direct it to the file u downloaded and it should pull the necessary drivers from there and see if that does the trick...
View attachment android-usb-driver.zip

No dice so far guys...but i have made progress in identifying the issue (sort of).
So here's the deal - the ONLY way the phone is recognized is if i toggle the "debugging" setting.
If i plug the phone in with the switch set on (meaning USB Debugging enabled) the phone is not recognized. Pointing the unknown device to the drivers (any drivers) does nothing.
However, if i plug the phone in with the switch set off, it finds a usb mass storage device. Then i turn the debugging switch on, and it finds the ADB Android phone with no issues. Then i can push commands via ADB without any problems.
The problem i have is that I cannot toggle that switch if i boot into HBOOT menu. So the comp never see's the phone.
I've tried this experiment on Win7-64bit, Vista-64bit, XP 32bit, and even MAC.
The same situation seems to apply everywhere, and with all of the drivers I've tried. None of them seem to allow the phone to be plugged in and automatically be found. The only way for the comp to see the phone is if i toggle the debugging switch off, then on.
At this point, I'm ready to put out a bounty on this. $20 via PayPal to anyone who can walk me through it. Bottom line is that I need to be able to see the phone without having to toggle the debugging switch. That will allow me to boot into HBOOT and still send commands to the phone via ADB.
Thanks for all the help guys. Hopefully, we can get this resolved.

Anyone care to take a shot??

[Q] USB Device Not Recognized

Good day,
I'm having problem with my DHD unable to be recognized in my Win 7 PC. I have already install HTC Sync and also tick on "Ask Me" for Connect To PC setting. I'm running on stock 3.13.707.4 ROM with S-ON and unrooted. Even restart to Fastboot my PC still unable to recognized my DHD.
From Googling it shows many Desire having USB-Brick problem, does this problem also applied to DHD? Is it my phone is hit by USB-Brick? Any guide to solve this problem? I've tried flashing older ROM via Bootloader and PD98IMG.zip but it won't allow saying something like the ROM is older version.
I just bought this used phone for about a week so I'm still not sure on how to solved this problem. any helps is much appreciated.

are you using the original cord that came with the phone? just any old usb cable won't work
also you can't flash a new rom without rooting and gaining S-OFF, you're unrooted and S-ON, that's why you get the "version is older" message

I bought the phone and it came with 1 cord (with HTC label) that can be connected to the charger, I guess there are only 1 cord for charging and connect to PC? This is the cord that I use. In addition to that I have also tried Motorola, Sony Ericsson (both also for Android phone) and Nokia cord but all can't.
The ROM is actually older version stock ROM from RUU.exe. I saw from few Desire thread they were using this method to restore the ROM to before the USB Brick condition so I thought to try it.

BUMP!
Anyone know what should I do to resolve this problem?

Are you running the very latest HTC Sync on your PC? I'm using 3.0.5606. You can get it here: http://www.htc.com/www/help/
Also, connect your phone and go into Device Manager on your PC. Check to see if you have an entry for Android USB Devices and that the phone shows up. See attached screenshot for how mine looks. This is the best place to check to see if your PC has installed the drivers correctly.
In answer to your question about the cable, yes it's the same cable that attaches to the PC or to the mains charger. I've sometimes had connection problems caused by a dodgy cable, but I've used others apart from the HTC one without issues.
Edit: Also, when you install HTC Sync it should warn you to disable Antivirus software during the installation. This can be really important! I ignored it the first time around, thinking it was just a silly precaution, and had loads of problems with the phone not being recognised. Had to uninstall, temporarily disable AV, and re-install HTC Sync. Once it has finished installing, you can turn your AV back on.

Thank you for your reply preacher6.
Yes, I'm using the latest HTC Sync, v3.0.5606, just downloaded yesterday and reinstall everything.
When my phone connected to the PC it didn't appear as Android USB Device on my Device Manager, it only appear as Unknown Device in USB Controller:
So I guess I can rule out the cable as I have tried about 4 cables already.
For the installation part, I have disable the anti virus and also running the setup program as administrator. When installing there is no problem whatsoever that crop out.
Another point is, even on Fastboot it appear as Unknown Device in the PC.

I would try to update the driver manually - right click on the Unknown device, go to "install driver" or "update driver", then browse to the "Program Files\HTC\HTC Driver" folder. See if it picks up and installs the correct driver.

I've tried manually update the driver as per your advise but it says there is no compatible driver in that folder even though androidusb.inf is in that folder.
I'm running Win 7 64bit. does the driver also work for 64bit OS?

Should do, yes, I'm on Win7 64 bit myself. There is this folder on my PC:
C:\Program Files (x86)\HTC\HTC Driver\Driver Files\Win7_x64
Is the unknown device present when the phone isn't connected? Just to make sure that is actually the phone - if it's still there when the phone isn't connected, it's some other device.
Otherwise try uninstalling the unknown device and then rebooting the PC, then forcing the installation of the drivers again.

The folder is same as yours.
The unknown device does not present when my DHD is not connected, so I'm certain it is the phone that appear as unknown device.
I have tried uninstalling the unknown device > reboot PC > installing the driver but it still won't install.
Another thing is, I check on the Device Manager > Unknown Device properties > Details" for it's Hardware Ids and it shows as USB\UNKNOWN. I think it should show a strings of the device id? Correct me if I'm wrong.

Yep, there should be a proper device ID string, on charge mode mine shows a hardware ID of USB\VID_0BB4&PID_0CA2&REV_0226&MI_01.
At this point the best thing I can suggest is to try on another PC. If it works, your drivers are screwed up and you'll need to strip them and reinstall. But if it doesn't work on another PC, it's possible you have a hardware problem with the phone.

I need help too (HTC Desire Z device)
Is it hardware problem? (I already purchased new system board).
For me it looks like hardware problem, because device does not accept bus address, do not show USB strings/VID/PID (Tried different cables/PCs/OSes (I have OpenSUSE linux, but phone does not connect to usb on any PC, Windows PCs even do not understand that something plugged in)).
No problems with USB-connector (checked resistance), but I do not see pull-down resistance with my tester.
But all other functions work well.
UPD. Tried to connect from FASBOOT/HBOOT/Android - the same result, device does not accept bus adress. Additionally it charges without problems, but when I connect phone to USB no pop-up/information at top bar appears.

Sorry, it looks like I explained my question wrong (I'm Russian, and English do not native to me). Let me try reformulate:
You said "Yes. Holla if you still need help" so I believe that you were able to fix "Device not recognized" problem. So I'm asking - how did you do it? Did problem was hardware or software?
For me (look at symptoms at my previous message) it looks like dead USB controller in phone. But maybe it very strange software problem (USB-controller firmware damaged)?
Did I explain it clear now?

Install the SDK on PC and update all android versions.

Well guys it was just my PC, i made a system backup for four days and that was all the problem(the USB port of my PC)

After installing and updating SDK...go into platform folder and open it. Hold mouse in field and hold shift and right click mouse. Chose "open cmd here"..that will open a cmd prompt window. In regular mode on phone,type "adb devices" should return numbers (ex: hta3829g)..if in bootloader mode,type "fastboot devices" should return numbers.
This SDK helps PC see your phone when its plugged in. Especially handy when a PC won't install drivers for your phone

My phone just won't connect to my PC

I'm running 4.1.1 and every time I plug my device in (With stock USB) I get "USB device not recognized"
I've tried another USB. I've downloaded Kies (Will only connect wifi), I've tried reinstalling drivers, I've tried using another computer as well. I've also enabled/disabled USB debugging,
The USB connection notification only appears sometimes, and even when it does my computer still won't recognize my S3. After I reinstall the drivers my phone does say "Connected as a Media device", but then the notification goes away..
FYI, I'm trying to root, that's why I need a direct connection with my computer so badly.

Does your computer has samsung kies?
You say drivers. Idk what u mean but all we need is samsung kies.

I tried your method a few days ago, and it didn't work. I tried your method again.. it doesn't work.

I had this issue. All I did was get some good ol canned air and blew the dust out of my micro usb port. After that it connects just fine. Was about to do a warranty exchange before I did this.

Its your rom on the phone that's causing this. If you want to rule it out, why don't you just do a nandroid backup and install stock rom or perhaps the same rom clean from start. I had this issue before and it was fixed with reflashing clean rom.

Tried it with W7 & Mac, neither recognize the device. Android file transfer just tells me "no device found", and the Kies on mac doesn't work either.

I still won't update my computer from XP cause all I read are device errors with upgraded versions of windows... see if you can get your hands on XP and try. Just as insurance, you have gone through device manager and removed all drivers for the phone and then pushed the proper ones from Samsung, correct?

After a few moments, (with the phone still connected) click start,right click on my computer, select manage and select device manager.
are there any yellow question marks on the right side under the computer?
Open the modems (click the + sign) is there any SAMSUNG USB Modem? (should have no yellow question mark)
Open Universal Serial Bus controllers, do you see the samsung Mobile USB Composite Device?
There should be NO yellow question marks or exclamation marks anywhere on the right panel.
If there are, there is a problem with your computer settings/drivers or services.
If you followed my "cannot fail" steps EXACTLY in the order I had it, and did not skip anything, you should be without any problems with the modem connectivity. That includes the uninstallation of any samsung drivers previously installed.
If you do not even see the samsung modem, the cables or the phone may be your problem.

My bad, speed reading is not always good... thanks for pointing that out.
Anyway, did the OP ever get this resolved? Bobolinko's steps are thorough and if that didn't fix it, why don't you just try to go into download mode and ODIN a stock ROM with root injected into it already? It's another option...

Did you try buying a fresh new cable to connect the phone to the computer? I only have those issues with corrupted USB cable and a messy laptop...
Also when that notification appears for me I go to my phone USB section and tells it to mount as storage...and if its on storage I switch media than back to storage...always work for me.

I've tried this as well. I get this error:
"Connection problem or invalid MMI code"

The problem is with your computer, and not the phone. You CANNOT get it connected with a problem in the USB settings.
click on the yellow exclamation items and DELETE or UNINSTALL them. then reboot the machine and it should reinstall automatically. If your DRIVERS that are already in the machine are bad, you have to get them updated or replaced. uninstall KIES from the computer, reboot, and reinstall it. go to samsung's site and download and install the driver for your comuter.
The one for the xp is: SAMSUNG_USB_Driver_for_Mobile_Phones_1.4.8.0.exe
install it to your computer and be SURE there is no error while it installs.
then check again your device manager list for any yellow problem areas
connect the phone and wait a while, then, disconnect and wait about a minute
then again, connect the phone, and wait at least one minute. open the device manager page and see if there are any yellow area problems again.
are you positive you have the latest window updates?
you can sometimes right click on an item and do the driver update and fix a problem.
You clear all the COMPUTER END PROBLEMS you have and the phone will connect. That, my friend, you can take to the bank.
Good Luck!

[Q] Device undetected by Windows.

After going through a replacement process (twice) after cracking the screen on my first device, I was relieved to find that the replacement I got sent wasn't updated to un-moddable status. However, after using rumrunner to s-off, flashing cwm 6.0.4.8 recovery, and using that to install cm11 m6 snapshot, I was disappointed to find that my phone will not connect to Windows in a manner where I can access USB storage. Enabling debugging in dev options does initiate the "device plugin sound" from Windows, but after looking in device manager, all that shows up there is "Android ADB Interface". When debugging is disabled, Windows makes no sounds, and there is nothing in the device manager. The only response i'm receiving is that the charge light on the device comes on. I would try to install drivers, but seeing as the computer doesn't even recognize that a device is plugged in, i'm pretty much halted on that front. Any comments or solutions would be greatly appreciated.
Cheers!

Unfortunately, as the computer doesn't even react at all when I plug in the device, I can't manipulate drivers at all. That means no uninstalling or installing :/

which windows are you on?
also HTC driver was an EXE file so you should be able to find in the uninstall program portion of windows.

ah okay, install sync manager:

once the windows sees the phone. feel free to remove the sync portion of the install and keep the driver installer on the pc.
this should fix it and wont mess with ADB or fastboot.

Hehe, thanks. I guess I'm just a little paranoid about having junky, manufacturer specific software on my pc. Will see if this works.

me too. :/ but i found that this was the less headache way for me. sync and drivers will show up as 2 different installers. i deleted sync and kept the drivers. im sure one can uninstall the driver installer part of htc software and windows will keep the ini file intact but i never tried this.

[Q] HTC M8 not being seen in adb

OK using a windows 8.1 Pro laptop, ADB installed properly with HTC Sync Manager, both Windows, HTC Sync Manager and the Device Manager in the Control Panel can see my phone. I tick on USB debugging and then press revoke USB debugging authorizations. Unplug my phone and plug it back in. I'm using the original USB cable from HTC. Everything pops up and shows like it's connected, except when I type in
Code:
adb devices
in the command prompt, then it just comes up blank. I've attached screen shots so you guys can see what I am talking about. If you have any ideas it would be much appreciated. I've attached some photos just to show that I've dotted all my i's and crossed all my t's as far as I can see. I also want to point out this is the second computer I've tried this on.

Might be a driver issues... Try those: https://www.dropbox.com/s/nr91z4bveeugaow/googleUSBdrivers.zip?dl=0

1) Unplug the phone from your computer
2) Uninstall anything related to HTC (drivers, sync managers..)
3) Reboot the computer
4) Install the latest (direct URL) HTC Sync Manager
5) I tend to uninstall the manager right afterwards (optional)
6) Reboot the computer & plug in your device
7) Report back

Yeah that didn't work, I even tried installing the USB Driver manually and that didn't work either. Still comes up as not connected, it's super frustrating.

Not sure if this helps but for some reason my Android Phone isn't showing up under Android phone in my Device Manager, it's showing up as Portable Devices. I don't know if this is an issue or not, anyone care to give an opinion?

That's normal as the phone is using MTP, the Android Phone entry only appears once the drivers are installed. It's definitely a driver issue but as to what I can't say as I have no issues on my 8.1 Pro laptop

I think I figured something out, just flash CM 12 - (God it's amazing. ) and now I can see my phone on ADB, so whatever ****ery was going on I am blaming it on HTC stock rom.

is cm12 worth the hassle?

Sorry for the necrobump, but I ran across this thread while researching the same issue on my M8 and wanted to save anyone else the trouble if they also stumbled across this same issue.
Though the solution discussed would likely work, if you don't want to hassle with a new ROM, it is possible to fix it on your existing ROM provided you have root.
[SOLVED] ADB 'unauthorized', no RSA prompt, and no 'Revoke USB debugging' option

Thanks for this guide you put up. Interesting that there was no option for you to revoke USB authorization. My device is S-ON and have been using Viper for a while with the option available. Same for HTC stock. Good for you getting that fixed. Had a similar issue on a different device months ago.
