Dear Maintainer,

=============================================================================================================

After changing to a Pixel 8 phone running Android 15, I tried to mount
it using jmtpfs but this failed every time.

However, I did notice this works **only** the first time I try it after a reboot.
Every subsequent time fails after it fails to reset the interface.

There seems to be some missing cleanup/initialization after the first time this is mounted.

=> mtp-detect

I neglected to mention that this works fine with a Pixel 4 phone running Android 12.
