    My desktop computer can no longer mount my Pixel after 8.0 Oreo through the USB 3.0 connection with Windows or Linux. USB 2.0 works with both Windows and Linux.

    I have the Pixel with Android 8.0. I have a desktop with Windows 10. Using the cable that came with my Pixel with USB C and USB A, my Pixel connects fine with my desktop. My desktop immediately beeped and asked me what I wanted the new device to do.

    You do realize that, after physically connecting, you need to

    1. Make sure the Pixel is powered on and not locked and
    2. Drag down the notification bar; look for something that says (okay, I forget what it says exactly but something like connected to USB for charging...) - tap that and select File Transfer Mode.

    Yes of course I know the obvious of the pull down and selecting file transfer mode. I used this computer and this phone everyday to transfer music back and forward on USB 3.0 prior to Android 8.0 update.

    My power supply is a 630W, and the board is an FM2 Gigabyte using a quadcore 3.6Ghz. Homebuilt and stable as a rock for a solid 5 years.

    Thank you for the responses. I can only assume this is a bug that will be fixed with an update.

    Sorry for stating the obvious, but many people do not know these things.

    I can tell that my Pixel still connects to my Windows 10 PC without any issues; just transferred some music yesterday, as a matter of fact.

    One thing that has worked in the past, go into Windows Device Manager and delete *all* entries in any way related to your phone or any other Android device. Reconnect your phone and see what happens.

    I have done the device manager route in Windows, and rescanned for new devices. I end up in the same situation where Windows or Linux does not even seem to recognize the device through the USB 3.0 port that was used everyday with Android 7.

    If others with USB 3.0 can test this out, that would be great! Thanks!

    I had this same problem on nexus 6p. when i plugged in id didnt ask what i wanted to do with the usb connection so it just charged. in developers options under the networking header there is "select usb configuration" where you can select mtp or whatever you want to do. worked for me. HTH

    edit: i did confirm the device was recognized by adb first.
    edit2: annoyingly, I also have to do this everytime as it does not remember the setting.

    Have you checked for updated USB drivers for the PC?

    I'm having the exact same issue since upgrading to Oreo. Device mgr showed 'pixel' under Portable devices, with an exclamation. I Removed it and now it comes back showing 'MTP USB Device' with an exclamation. Still Not working. I have tried it on 2 other Win 10 PCs and it works normally as it always did. I'll have to try copying the drivers off the working PCs.

    Mine's still working on Windows 10 as well. Definitely not an issue with the phone hardware or with Oreo, but with your Windows drivers.

    Similar issue here too. Pixel XL didn't ask me what to do with the usb connection. I have tried with USB 2.0, USB 3.0, WIN 7, WIN 10, all failed....it cannot be recongized by adb either, and no response even I selected MTP in the developers options....

    OTG usb works well so at least the hardware itself should be fine....

    I have the same problem with Mac OS 10.11.6 and Pixel XL (Android 8.0.0 with latest updates) using Android File Transfer program (latest version). Send feedback to google.

    But it runs fine with Mac OS 10.12.6 inside Parallels 13 VM using Android File Transfer program (latest version).

    The problem seems clear to me and it's OREO. Since I have owned by pixel I have been able to connect it and transfer files to my WIN 10 computers USB 3.0 port until Android 8.0. Now I have to use one of my computer's USB 2.0 ports to transfer file, the USB 3.0 port no longer works.
    Google owns Android, Google owns Pixel and Google owns this problem THEY need to fix it!

    Dell laptop. Windows 10. All 4 USB 3.0 ports connect to my Pixel XL. As do the USB 2.0 ports (I have two of those).

    The problem seems clear to me and it's OREO
    Problem is not so clear now.

    There fixed it. Works fine on my Lenovo PC on Windows 10 as well. Seems I have the correct drivers installed.

    Make sure you are plugging directly into the computers USB port and not a USB hub. I had the same issue until i connected direct to the computer.

    I have a Nexus 5X running 8.0.0 build 170623.023 and I cannot connect to my HP Windows 10 Zbook 15. I tried both USB 2.0 and 3.0 (directly on laptop) and through a hub and no recognition by Nexus 5X. It worked fine prior to upgrading to 8.0.0 and I tried three different cables from different manufacturers. Google needs to work with Microsoft to figure this out as Google did something to change things.

    Weird, I was just dumping a bunch of stuff on my wife's 6P yesterday, using 3.0 (2 hubs deep, the PC hub/faceplate and a secondary), and it worked flawlessly.
    I did have to choose PTP or File Transfer though, manually, whereas I'm pretty sure before it "trusted" my PC, after the first connection.
    Edit: this could be a USB 3.0 driver issue, in particular if your chipset vendor or OEM did a poor job of adding feature or something, and are failing to properly forward metadata, or similar.

    The "trust" thing is weird though, but I could see Google implementing that, it (mostly) makes sense, from a security perspective.
    It's like like when you enable 3.5mm jack use while locked, it throws up a big "security warning", since it's a big, gaping security hole, at that point (not that most users even read the verbiage ;-] ).

    The issue appears to be related to Android 8.0/8.1 always wanting to transfer in USB 3.1 mode using 128b/132b signalling. Therefore if your motherboard only has USB 3.0 ports that only support 8b/10b signalling, you will likely have issues, unless you use a USB 2.0 cable, which will downgrade the connection to USB 2.0 (even on a 3.0 port) and then you will be able to transfer files.

    See this Google product forums thread for more information : https://productforums.google.com/for...w/md48EI_RAgAJ

    I've posted a YouTube video in that thread that demonstrates the different failure modes and combinations of USB 2.0/3.0 ports and USB 2.0/3.x cables in that thread to help others troubleshoot the issue also.
