### Qubes OS version:
R4.0 up to date current, Android 11 (Pixel phone up to date 5 dec 20 - reference platform)
f32 target Qube, f32-min sys-usb
### Affected component(s) or functionality:
USB handling - dom0
---
### Steps to reproduce the behavior:
Attach Android 11 device with file transfer enabled to a Qube running Nautilus.
### Expected or desired behavior:
Entry for device appears in menu in Nautilus and I can select that item to browse the filesystem on the Android device.
### Actual behavior:
Menu item appears as expected, however selection goes away for 5-10 sec then gives a popup "Unable to connect to MTP device 00n,00n" and deletes the Nautilus menu item.
### General notes:
Please see forum thread for more details:
https://qubes-os.discourse.group/t/how-can-i-connect-to-android-via-usb/2101
An older v8 Android does partially work: same error popup in Nautilus, dismiss that, detach and reattach, then works as expected.
If looking into this I did notice another bug in the device widget communication - if Android file transfer is enabled or disabled while attached to a Qube the attachment is dropped in dom0, however the widget is not notified. Attempting detach in the widget gives a not attached error popup.
