I'm on a fresh install of Windows 8.1
Here's what I did.
1. Installed HTC Sync Manager
2. Installed Minimal ADB and Fastboot
3. ADB works fine, boot into bootloader.
4. Windows shows Unknown USB Device (Device Failed Enumeration) in Device Manager
Running fastboot devices returns nothing
I can connect my phone to view files, I can ADB on my phone, the only thing I cannot do is fastboot. Why is this happening and how can I fix it?

I just experienced the exact same issue following the same steps on my laptop also running 8.1
Fastboot doesn't work w 8.1. No workaround. You need another OS.

Uh no. I have it working perfectly fine on my Surface Pro. It has both USB 3.0 and Windows 8.1. I'm not sure exactly how I got it to work but its possible.

From all of my research, you're the first person I've heard of having it working. Any specific drivers used? I'm very curious (currently, I have to use a backup machine to push TWRP updates to my VZW One)
Same thing here. 8.1 broke fastboot. Is this a Microsoft problem specifically because if it is I seriously doubt they will be in a hurry to patch it.

I have found out something based on the VMware experience. Can somebody try it out and report back???
I feel that the fastboot problem in windows 8.1 is related to the USB port.
For those people that having problem, are you guys using USB 2.0??? If yes do you have USB 3.0 port in your computer??? The real problem maybe is that fastboot only works with USB 3.0 but not USB 2.0 in windows 8.1...
I tried both USB types, and half a dozen drivers and workarounds, and nothing.
I don't believe the dude above got it working. He is probably thinking Win 8, not 8.1. I have it working on 8.
Flash Image GUI will probably do everything you need to do in fastboot without the need for a computer. I just threw 8.1 on one of my extra PC's, I'll see if I can get the drivers going. I feel like this was answered in another thread though, I think it is in the rumrunner thread...
Just another reason why 8 is bad

i just used http://www.droid-now.com/2013/10/fix-working-fastboot-drivers-windows-8-1-x64/ and fastboot works on a 3.0 port on 8.1
I've just had this problem last week, and now got a solution...
Hi guys,
For anyone interested, due to something DreamerTKM said - I tried both USB 2 & USB 3 sockets on my Dell L701X laptop and both failed:
ERROR: Unknown USB Device (Device Failed Enumeration)
I did a clean install of Win 8.1 Pro and it still failed...
Anyway, I was using Windows 8.1 Pro default drivers for my system when this issue came up last week - default as in Microsoft's own out of the box drivers (drivers on the install DVD and Windows Updates) for my CPU chipset, USB chipset, etc... - my entire system (except for my nVidia graphic card!)
My laptop is now a few years old and my official "Dell" CPU chipset drivers are not compatible with Win 8.1, so I need to rely on Microsoft for these, but my USB 3 originally had Dell supplied "Renesas USB 3" drivers which I hadn't installed or even thought about installing as my USB 3 socket worked - and worked well...
...anyway, after installing the original Renesas USB 3 drivers the fastboot commands work once plugged into a USB 3 socket! USB 2 still wouldn't work though, but now my Win 8.1 laptop can do fastboot commands through a USB 3 socket.
I understand not everyone will have a Dell L701X laptop but the moral here is before blaming Microsoft and their Windows 8.1 O/S (which is truly awesome), try installing the correct drivers first!
DreamerTKM - thank you for putting me on the correct path with this!
Hopefully this post may help some of you!

guyz if u r working on win8.1 just plug it in ur usb 3.0 then it will wrk...if u put in usb 2.0 it wont!
No changes. I have read a few topics that it barely works with Win 8.1, so I will have to try it somewhere esle with Windows 7, then I'll be coming back to tell what's up.

I have been using fastboot and adb with no problems on Windows 8.1 since January. But the issue is much more than simply using a different USB port. Here is the tutorial I used. http://www.droid-now.com/2013/10/fix-working-fastboot-drivers-windows-8-1-x64/ Certain security features of 8.1 need to be bypassed to install the modified drivers. Also see this guide: http://forums.team-nocturnal.com/index.php/topic/1362-how-to-adb-fastboot-in-windows-xp-7-81/ I used this just for ADB, but it looks like he's updated his guide for fastboot as well.

You need to install Win7's USB drivers on Win8 in order to get ADB/Fastboot working on Win 8. I drove myself mad until some kind soul here (can't remember who) provided the following link. Hope this helps some of you exasperated with getting RumRunner working.

be warned, I have tried this 3 times already, and at some point throughout, on EVERY try, my computer would just STOP recognizing my USB devices, and I would have to use a recovery image on my computer because i couldnt log in to my desktop.
YMMV, but it didnt work at all for me
I made this guide. What I had to do was edit some Windows8 settings and install the drivers manually to get them to work.
This worked beautifully for me on Windows 8.1 RTM x64, thanks much.
I tried all this and still couldn't use Fastboot. My fix was in BIOS. I disabled xHCI mode in USB under advanced tab and everything is fine.
Worked great for me! Thanks!

Guys the problems with windows 8 and windows 8.1 are normally the usb 3.0 drivers. Intel have not posted windows 8 drivers for series 7 and series 8. You need to modify the windows 7 drivers with other inf files. I have done the job for you so you can manually install the drivers.

Hey.
So i just received my N7, first of all i want to get adb/fastboot working.
Enabled USB debugging, installed SDK (along with USB drivers from SDK).
After plugging USB my device was installed as "Google Nexus ADB Interface" under "Android Device".
Homever when i use "adb devices" or "fastboot devices" it's not detecing my N7.
Did i missed to install something?
Edit:
After connecting it as Camera (PTP) it's detected in ADB, but not in fastboot.
Edit2: Ok i figured everything out, unlocked and rooted already - fastboot / adb is working
And lastly will i be able to download official 4.4 OTA after unlocking my device and with root?

Are you booted into bootloader when you try fastboot?
I guess you figured out as I was replying.
Yes, you can use the ota, but you didn't need to unlock nor root for that. By unlocking you can additionally use the factory images and also can install root.

If you're wifi only (flo), build JSS15R, You can download the official 4.4 OTA right now.

Since you're rooted, you have a custom recovery. Download the 4.4 OTA on your Nexus 7, reboot into recovery, and have TWRP or CWM install the zip from sdcard (the same way you installed the superuser binaries when rooting).
I had the same problem where Nexus 7 2013 was not detected when booted into bootloader using adb in windows 8.1. I found a website called pdanet.com where I was able to get a USB driver that worked on windows 8.1 and detected OK.

Thanks for the info. I managed to get my Nexus 7 Flo Tablet to show up in "This PC" Last week. I don't even know how I did it (some combination of drivers worked), but when I went to add a new ROM today, it went missing again today...
I am running Win 8.1 on a Gigabyte Z68 MoBo.. This board has the Intel series 6 chip-set..,
Anyway, Would you happen to Have "The FIXED" Intel series 6 - 64 bit drivers for windows 8.1?
BTW....
Happy New Year To All! Mrwirez / Jim
As some of you may know, Windows 8 and 8.1 kills ADB and Fastboot. Does anybody have any workarounds?
Right now I can only get "Device Failed Enumeration" in device manager.
We really need HTC to send out some updated drivers.

Windows 8.1 changed unsigned driver policy. Again. Every version since Vista has made it increasingly more difficult to install drivers that are not WHQL verified.

Be Advised, Under win8.1/X64 that if you have(like me) an Intel 8 /c220 (or with a 4th generation like intel I7 4770k) you may encounter a big mess , and perhaps you''l have to do a clean install of win 8.1 : all the usb2 DEVICES were disconnected after the first iusb3xhc.inf driver install !! So no more usb/Bluetooth keyboard+mouse , fortunately i had an old ps2 keyboard and i was able to delete only with "tab/alt Tab/ctrl tab" keys the "intel usb3 extensible " line in device manager, and as soon as i done a refresh (ALT+A) in device manager the previous driver(Microsoft) was reinstalled by win 8.1 andall the usb2 devices connected (mouse/keyb/hub etc)
http://plugable.com/2012/12/01/wind...host-controllers/comment-page-3#comment-19066
see there there's in the last comments at the bottom , Andrew(tks to him!)a link + modified drivers for intel8/c220)
and for me it worked mouse/keyB were functional during all the process
next step check the fastboot adb is working now
Try creating a live ubuntu CD and run that. You will then be able to use the Linux platform to adb without editing your boot partition on your pc.

You'll need to remove drivers reboot, install correct drivers, reboot and then be nice to everyone you ever meet and it'll show up. It's a real pain but you can get there. XDA tutorial all the way there!
I once have kind of youre problem connecting to my laptop (win.10). But, at work, on that laptop, connection was ok (win.7).
I reinstal windows 10 and connection works fine, since.
I allways use latest TWRP & version of rom. I can't tell for sure what it's goin on with youre phone.
If i was in youre situation i format my phone (this will erase ALL in youre phone). And if PC still does not see the phone reinstall windows.
Also: Try a different cable.
A cheap cable could have a charging pin layout but lack data pins connections.
9 out of 10 issues with connecting to PC and getting odd behaviours is due to a bad/wrong cable.

Find the excellent tutorial here on drivers.
For some reason my phone didn't show up but was able to receive commands. It was frustrating because I wanted to use the all in one XDA product but couldn't.
Even if you installed drivers they can be broken!
Do drivers from scratch per xda tutorial. Don't forget reboot!
Try different cables and usb ports! My front ones never seem to work!
Don't just try fastboot commands also try adb. Like I said mine wasn't seen properly yet it took the commands.
Unless your windows is a years old install it shouldn't require reinstall.
Factory phone reset might help.
Best of luck!
Hey, after updating from CB1 to Oxygen OS 9.0.2 i can't access the device (OP3) via fastboot anymore. I have installed all needed drivers and adb is working as it should.
What is strange is, that my device is always shown just as "Android " with a "!" next to it.
Device has been updated via official full update (Downloaded w oxygen downloader - full update)
I have already tried to reinstall the device in the device manager
I have completely reinstalled all ADB/USB drivers
USB debugging is enabled
Has anymone having the same issues? Under CB1, everything was fine...
Have you tried different USB ports? Even other PC's?

Sounds like ADB/Fastboot drivers aren't installing properly. You have looked up the right way to install those drivers on Windows 10 haven't you? by disabling driver signing enforcement:
https://ph.answers.acer.com/app/ans...windows-10:-disable-signed-driver-enforcement
ADB/Fastboot works for me and a lot of other people.
It's not a OP3 problem.
Good luck.

Check my last reply. I know that its not a OnePlus specific problem, but when I faced this problem the first time, it was right after the Update to pie - which was a coincidence.
Thanks for the advice with the driver signing enforcement, I will try that!
