When I connect Quest to PC it just shows up as a portable device "quest" in device manager and Windows Explorer. The folder is empty on windows. Currently what I have to do is go to the Phone APP and toggle developer mode OFF then ON again for the message to appear in the headset about accepting the connection. I have updated the drivers (see support message below) but each time I need to connect it requires this dance with the phone app. This is pretty unfeasible seeing as it's not my phone and I don't always have access to it. Any suggestions please?
If your Oculus Quest headset is not appearing as a drive on your Windows PC:
- Make sure that you use the included USB cable from your Oculus Quest package.
- Make sure that you select Accept in VR from your headset to allow your computer to access files on your headset.
- Update your device driver:
- From your PC desktop, right-click on This PC or My Computer.
- Select Computer.
- Select Manage.
- Select Device Manager.
- If you can't see the Manage option, just select Device Manager directly.
Click the > next to Oculus Devices or Portable Devices to expand your options.Right-click on Quest and select Update Driver.Select the Browse my computer option, then the Let me pick from a list option.Select MTP USB Device and then select Next to complete the update.

I have developer mode activated.
What I had to do was disable developer mode.
Accept the MTP request in the Quest.
Then after re-enabling Developer Mode. MTP worked fine.
The accept MTP dialog did not show up with developer mode enabled for some reason.
Thanks
I have to
1 turn developer mode off on the iphone
2 connect to the PC again
3 accept the permissions notification in the headset
Having to use 3 devices to resolve something that should just work once plugged in is annoying.
Once a device is given permission I shouldn't have to do it every time I connect and go through the above 3 steps.
Please fix
You have to shut off the app on the PC and then disable it in the Quest 2 HMD.
Once disabled you can go and toggle (a couple times maybe?) Enable Usb connection dialog and then connect the headset.
Worked for me.
