#1843 Regression for Cat S30 phone
After the last system upgrade my Android phone is no longer accesible with MTP. It used to work fine; libmtp seems to be unchanged since october 2018 so the problem could be elsewhere? Either way, the device is unlisted.
The phone is a Cat S30, running Android 5.1
$ mtp-detect
libmtp version: 1.1.16

Device 0 (VID=04b7 and PID=88b8) is UNKNOWN in libmtp v1.1.16.

NB: the message from Dolphin (the file manager) is: "No storage medium found. Make sure your device is iunlocked and has MTP enabled." (it has...)
we track the S30 as 88b9 ...
can you see if the device has some mode to switch between "charging only" and "file access"?
Modern Android phones pop up a dialog for this.
