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.
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.
I don't own any USB-C devices or cables at this time.
I am planning to buy Pixel 3a soon and would like to understand whether it comes with everything I need to connect it to my PC that is 6 years old and equipped with USB-3 Standard A connectors on motherboard. The objective is to transfer files in both directions.
From what I understand 3a comes with USB-C to USB-A adapter in the box. Does it mean I don't need anything extra to connect to PC to transfer files? That is it seems I would plug this adapter to motherboard, then USB-C cable to the adapter, then another end of USB-C cable to the phone. Is this correct?
And if I wanted one-cable solution then this is what I would want: https://www.amazon.com/dp/B01E9W8KY...colid=DAYIUPLW7ZM8&psc=1&ref_=lv_ov_lig_dp_it, right?

You would need to get a cable like the one in your link to connect to PC.
The adapter it comes with allows you to connect a USB thumb drive to the phone.

I'm pretty sure you could also use it to connect a male to male USB A cable to connect a phone to a computer.
But yea, a USB-A to USB-C cable is the easier option.

If you need to plug it in to your computer yes, you need an additional cable. But for data transfer only just use ftp, no cable need and probably faster

I find adb is far faster for data transfer when it wants to work tbh.

I just got a 3a and can't get the phone to connect to my PC properly for file transfer or adb use despite the phone showing properly on device manager and having had it work fine with an S9, G7 power and even a previous 3a. I'm lost.

I don't have the 3a but I saw in one of the videos there is a setting in the phone that defines what to do when phone is connected to a computer. One is "Charge Only", another something like "File Transfer" (and I think there are others). Could it be that you have it set it to "Charge Only"?

It's likely one of three things.....
1) You haven't installed the latest ADB drivers (although this is unlikely if you had it working with this computer and another Pixel 3a).
2) As already noted, by default you have to manually change the connection type to "Data Transfer" anytime you plug your phone into a computer. When you plug the phone into the computer, you should see a new "Android System" notification on your phone. Open that notification and change the connection type from "Charge Only" to "Data Transfer".
3) To use ADB, you need to make sure you have turned on Developer Settings and turned on "USB Debugging" in the developer settings.
If all of these things are correct, then I would "Revoke USB debugging authorizations" in the developer settings and then plug the phone back into the computer. You will see a new authorization popup on the phone which you need to accept.

Not really. There's no such thing as a Type-A to Type-A USB cable in USB 2.0. You can probably find a cable with USB 2.0 connectors on both ends, but they violate the spec, and can't properly be called "USB." (there's lots of crap like that around) In USB 3.1, there's a very specialized one "defined for operating system debugging and other host-to-host connection applications."
The adapter included with Pixels is a USB "On-The-Go" one, it tells the phone act as a USB host (so it can connect to a thumb drive, keyboard, USB headset, etc.). Per the spec "This cable assembly is defined for direct connect to a USB device (e.g., a thumb drive). System functionality of using this adaptor assembly together with another USB cable assembly is not guaranteed." Having said that, Google does provide the adapter to allow the Pixel to connect to another Android phone using its A to micro-B "charging" cable in order to copy data when changing phones.
To have the phone appear as a drive on a PC, the PC is the host. You need a USB Type-A to Type-C cable to connect to the Pixel.

Turns out there was a heavy Windows update pending upon restart. The thing bugs me about them constantly so I usually ignore them. I restarted and let it do it's thing for 4 hours (damn Windows lol) and after it restarted the phone for file transfer, as well as adb started working correctly.
Hi,
So the screen and touch on my OP6 are broken, and i want to get the data from the phone, but since i haven't got USB debugging turned on and i didn't authorize ADB, i can't do anything with it. I want to connect it to my PC and mirror the screen, and for that i need USB debugging or ADB.
So is there a way to enable USB debugging or to authorize ADB without touching the screen?
I've bought an OTG cable, but the phone won't recognize my mouse or keyboard.
Thanks!
I think there's no way to enable USB debug without go to developer options, only thing to do is to change the display, even temporally to get your data back... Do you have google backup disabled?
You can probably try connecting a USB mouse.
I have a device but the screen is broken, I don't see any pictures but the device is alive, there is a little light on the black screen, I tried to connect to the PC, it worked but I had to unlock the phone first.
and the essence of my question is how do I access my pc via usb debugging? Before usb debugging, there was a request for permission from the cellphone but my screen was broken, how do I do that or is there software that automatically allows usb debugging to be allowed
help please
you could try MHL HDMI multiport adapter and connect TV
