computer does not recognize shield

i'm trying to connect my shield to my computer to do some basic android development (i have an app, it works on other devices, want to test it on the shield).
my problem is, when i plug it into the computer, nothing happens. to clarify, i don't mean that the drivers don't install correctly and then i can't do anything. what is happening is actually nothing. the computer (windows 8) does not recognize anything is happening, the device manager does not see any new devices even after scanning for hardware changes.
the shield is in development mode, and has usb debugging turned on, but i don't get any response anywhere. the shield does at least appear to charge over the usb cable, but that's it. listing adb devices also provides no output.
do you guys have any idea what might be going on that the device isn't recognized on any level that i can tell?

It sounds like either the USB port or the cable you're using is faulty.
Have you tried switching USB ports, to see if it's recognized then? And have you tried using a different cable?

If youre just trying to connect thru adb you need the universal naked driver. If the shield isnt being mounted try a different usb port and make sure youre using the shield cable as well. My samsung cable will charge it but i cant transfer data with it.

Did this get solved?
Did this ever get solved? I have the same issue. I have tried everything everywhere has said to do with no luck.

[Q] Nexus 5 not connecting to computer (usb), does not show in device manager

Hi,
I would like to see if I can get anyones assistance with solving my problem. I have lost the ability to connect my Nexus 5 to my computer via USB. I had previously been able to connect the phone without any problems.
Connecting my phone to PC charges the phone but no drivers are loaded, nothing changes in device manager and I cannot see a change in windows explorer to view the memory card.
So far I have tried the following:
searches on various sites
rebooting phone, starting in safe mode, wiping all data, performing a hard reset
connecting other phones to usb cable to check that it is not a charge only cable, also trying several other USB cables
connecting phone to other computers
connecting other phones (HTC) to load drivers (then uninstalling drivers)
displaying all hidden devices in device manager and removing all drivers that resemble something to do with mobile phones
uninstalling programs I no longer require on the PC
using "wugs nexus root toolkit" to uninstall and re-install drivers
checking & unchecking MTP, PTP, developer options, USB debugging in various combinations to elicit a response from the computer.
I have also tried to visually check the connections of the USB port on the phone wondering is there is a break but I cannot see very well.
does anyone have any further suggestions to get this phone connected to a PC?
my only last thought is to attempt to open the phone and check the resistance of the plug connections.

Have you tried enabling and disabling usb debugging while plugged in?

Are you sure you're using a data usb cable and the usb port is good?

Same Issue
same thing happened to me today when i connected the device to PC.
Mine says unknown device on PC under other devices. so i hope my USB port is ok.but im not using the original SUB cable. i wonder that's is the issue. but it didn't bother me until today. my original cable is at my friend's house.
Tried updating drivers manually. But following error message occurs once i select the drivers folder and hit ok.
Windows was unable to install your unknown device
Please help.

so, not really a solution but while at work my phone fell on to a nice rock cracking the screen. I have replaced the phone and the new phone connects to the pc fine, drivers come up without a problem (I will put this down to a fault with the phone)
Thank you for your assistance

OPO no USB functionality

I've had my OPO for a little over 7 months now. My issue began when I had my desktop at a friend's house and plugged my phone into a USB 3.0 port to grab some videos off the phone when the phone suddenly shut off and would not turn back on. I thought it was bricked somehow but after leaving it plugged into a USB 2.0 port for some time, the charging screen came on and I was able to turn the phone on, but since then both OTG and MTP/PTP transfer doesn't work. If/when the phone is plugged into a computer, it gives an error and Device Manager shows
"Port_#0001.Hub_#0004 Unknown USB Device (Port Reset Failed)" and I'm not only able to charge the phone with one out the dozens of micro usb cables I have. I've tried several cables and a handful of different computers and OSs (Windows 7,8,8.1,10, Ubuntu 15.04, Kali Linux) all to the same result.
I'm running COS 12.1-YOG4PAS3JL, rooted, and have TWRP installed. The phone doesn't show up when in Fastboot mode or the bootloader either. Nothing changes when I disable or enable USB Debugging as well. With DriveDroid if I set the USB system to "Standard Android" the phone reboots and that seems like the closest I've been able to get to any kind of progress. I've gone through unbricking threads as well as Googled until my fingers bled but I'm yet to find anyone with a similar situation where the phone isn't bricked, the micro usb port isn't broken, I can't pick between MTP or PTP mode (USB Connection just says USB is now disconnected), and I'm not running a custom ROM. I tried replacing the micro usb on the phone so I now know that it wasn't that that's been messed up but I'm not sure where to go from here. Any suggestions or help is greatly appreciated.

PC does not recognize the iwork10

When i connect the iwork the PC with the cable Type C it only charges
When I connect with USB 2.0 nothing happens ...

Greetings!
I had this issue as well, keeping track of it via Device Manager on the PC. Sometimes, it says it's the Model #, other times (depending on if you're recovering, adb debugging) it will say is "ADB Interface". I'm in need of recovery and refresh for mine, which is how I figured this part out. It's not much, but open your Device Manager on your PC before plugging it in via the 2nd USB2.0 down on the tablet. Watch it. If on the Windows side, it should pick it up as a media device or the device model number. On the Android side, if USB Debugging is on (which mine already is, thanks to the last person who had it -- I bought it from Amazon.), the charging should show up on-screen, and the Device Manager (USB Device, last one down) should see it.
I hope this little bit helped.

Data Issues (e.g. viewing Phone contents in Windows) - Please help/advise

I think I'm doing something wrong, the Pixel 2 only works with certain cables, or something else (port defect, OS defect, special drivers needed, etc.). I wanted to transfer some files from my PC (Windows 10) to my phone. I have a USB 2.0 to type-C cable that I plugged in. The phone came up in Windows but the contents of the window were blank. I could not access any contents or view anything on the phone. In Settings under USB I saw it said "charging" so I selected "transfer files" and it disconnected from Windows and reconnected only to go right back to charging. I have locked/unlocked, restarted the phone, tried different USB ports, and nothing works. The only function that works is "charging." When I use the supplied type-C to type-C that came with the phone I can get it to work only if I plug into the computer, then the phone, lock the phone, and then unlock it using my PIN (not fingerprint). I ordered a USB 3.0 to type-C cable to see if that works. Is there something I'm missing on why the phone won't connect with a USB-A to USB type-C cable...except to charge? Drivers or something else?
Also...I've reset the phone once (that didn't work either)...and even tried enabling USB debugging.
Please help. Thanks in advance.

Well...I think I figured it out with more troubleshooting. Apparently, you can't connect this phone to a computer via a USB hub. I was able to get it to work by plugging directly into my computer. I tried it on two different powered USB 3.0 hubs and it didn't work. Not sure why or if there is a way around it for convenience.
