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.

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...

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.
**BUMP**
Anyone care to take a shot??
Hi everyone
I have a problem with the drivers on my PC
First time when plugged the S II in the PC, i think it loaded the wrong drivers, now it looks like I can't get the right ones installed
Even with Kies, and the toolkit is not working on my PC
Does anyone know how to remove this drivers completely from my PC?
I would appreciate
Hi,
I'm having some issues where the MTP driver fails to load. Tried all the obvious stuff and did a lot of reading of forums and stuff but can't find a fix. Could anyone help me to fix it please?
Here's what hardware I have and what I've tried so far:
Tab Pro 8.4 16gb wifi UK model, rooted.
Connected via cable to Dell XPS 17, latest USB drivers installed, win 7 x64.
First of all, I enabled USB debugging and windows installed drivers for all except MTP.
Tried installing the Samsung driver package, same problem. Uninstalled at present.
Installed kies, didn't work, wouldn't even connect to the device. Uninstalled.
Followed the instructions on the wiki but the suite software installs the driver succesfully but then windows won't accept the driver. Tried the workarounds in the wiki but still no luck.
Tried rebooting the tablet and leaving the cable connected.
Tried wiping the cache.
Tried restarting both the tablet and laptop after reinstalling software and drivers, still no luck.
Found several workarounds on my travels, one was a command line for windows to add to usergroup ( it's on the laptop downstairs, will add it to the post tomorrow).
One post said to change a registry entry...really? Tried that, and another registry trick, but still no.
Using the same laptop, I had similar problems trying to flash a custom rom onto an s4, but the CM installer worked first time. I've done a fresh install of win 7 since then.
Can anyone shed any light on this for me please? Is there any kind of workaround? Running out of ideas!
Thanks
Fixed this, well, kind of. Here's a quick rundown of what I did, for people like me who are struggling with connection problems.
I thought I had tried everything, was going to dump the whole thing and then remembered that I'd fixed some previous USB problems (sound card) by doing a clean boot.
First, remove Kies.
The only other thing that is required are the samsung mobile drivers from their website. I tried with and without and this would only work with them installed.
Restart your tablet, make sure MTP is selected.
You can find out how to do a clean boot for you version of windows here.
Leave your device connected via USB cable. Once you have clean booted into windows, windows will attempt to install the drivers from windows update, let it do this. It can take a minute or two to complete. You should then see a green tick in the notification area rather than the dreaded red cross.
If, for some reason, the driver doesn't install first time, you can unplug and then plug back in the USB cable and this should do the trick.
What I did find, is that the connection wasn't consistent, I could restart either my laptop or tablet and then it wouldn't connect, so I'd have to go through the above process again to get it to connect.
Doing this allowed me to flash the Clockworkmod recovery with odin 3.09, but for whatever reason, I was still unable to use the recommended Eimdall suite to flash cyanogenmod.
In the end, I downloaded the CM11 zip file to my tablet (via http) and then used ES file manager to move it to the SDCard root and then clockworkmod picked it up from there.
Also, once CM was installed, there were no connection problems at all, as far as I can see.
Hopefully this will help others in the same predicament.
OMG... finally got it working. I installed HTC Sync Manager again and decided to run it and see what happened. While it was scanning for music on my computer windows installed the drivers. More than once it seems.
Now I need to know if I can uninstall Sync Manager but keep the drivers. It keeps opening up and I don't know if it's safe to flash recovery if that's going to happen.
Flashed TWRP successfully and made my back up.
--------------------------
OLD NEWS BELOW:
Here's the deal... I just flashed the 3.x RUU so I'm stock but I'm unlocked and s-off. I'm trying to flash TWRP via fastboot so I can get a custom ROM on here. I turned on USB debugging on the phone.
First of all, that stupid HTC Sync manager keeps trying to install and I don't know how to stop it. Googling has not helped with this.
Second, I can't get the device to be seen in adb, or at least not online. I seem to be going backwards with all the steps I have taken to try to get this to happen.
I'm using dotatt's adb package. When I attach the phone while it is off windows looks for drivers and usually fails. One time it seemed to work and adb saw the device but then when it boots up that Sync Manager wants to install so I decline. Then my phone was seen but listed as offline.
So I tried uninstalling all HTC things on my computer and reattach phone. Didn't help anything. I tried installing the HTC Sync then uninstalling it thinking I would get the drivers, no go.
I grabbed these Universal ADB drivers http://www.koushikdutta.com/post/universal-adb-driver linked to from a twrp page here https://twrp.me/devices/htconem9.html
Nothing lists as a device in ADB at all now.
My windows Device Manager shows "Unkown Device" under "Other Devices" with no driver listed.
Tried this:
[TOOL] [WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer v1.4.3
http://forum.xda-developers.com/showthread.php?t=2588979
Still not working.
ACK! Can anyone help me out?
Is there still an issue with using usb 3.0 ports? I feel like I heard something about that way back when.
That's pretty much how it's always been. Best way to get the appropriate drivers is to install HTC sync, let it do its thing, reboot the PC, then uninstall HTC sync without removing the drivers. To the best of my knowledge, been that way since at least the days of the Incredible, if not before. At least it's how I've always gotten the drivers to use adb.
Yeah I remember that from the Rezound, which is why I did that, but it seems that the drivers didn't actually get installed this time until I let HTC Sync Manager start running and scanning my computer. That's when I saw the message that it was looking for drivers and twice it told me it installed them.
I would think it would have them installed during the 'actual' installation process. So I guess I just uninstalled prematurely. Seems weird. But it's working now so all good.
Hey guys,
I'm facing a problem: my W10 PC won't install the phone's usb drivers at all. It stay with the yellow sign and can't find the drivers anywhere - not even through Win Update.
I searched for them everywhere I could and without any positive results.
Do you know or have the USB drivers for this phone so I can install them manually?
On my laptop, there are no problems and I tried exporting all the drivers installed on the laptop and load them onto the PC but didn't find any driver so the PC could extract them. I can't access my internals on my PC cause of this.
Anyone?
Thanks in advance.
Solved: Apparently, Windows 10 Home Ed. is not capable of installing any kind of USB drivers (MPT, file transfer, fastboot, USB-debugging - nothing worked) for the device but re-installing with the Windows 10 Pro version, the phone got detected instantly and fully without any problems. Razer CC wasn't helpful at all, this time.
