I have a new laptop from 2025 (Lenovo Legion Pro 5 16IAX10 Ultra 7 255HX) a= nd the system I have (fedora 42 xfce) with kernel 6.16.5-200.fc42.x86_64 detec= ts something as MTP Wireless Device. There is an icon on the desktop. I think = that this is because of wrong detected Bluetooth device in the Bluetooth driver.= The laptop don't have any MTP device. gio mount -l shows: Volume(0): Wireless Device Type: GProxyVolume (GProxyVolumeMonitorMTP) mtp-detect returns: libmtp version: 1.1.19 Listing raw device(s) Device 0 (VID=3D0489 and PID=3De111) is a Vizio (for Lenovo) LIFETAB S9714.

I think that it started to happen after I'= ve upgraded to testing kernel in Fedora. This is a related bug in Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=3D2392938 I hope that the provided info is enough, I used Grok (LLM) to help with debugging. --=20 You may reply to this email to add a comment.
