sys-fs/jmtpfs-0.5-r1::gentoo - LIBMTP PANIC: Unable to initialize device terminate called after throwing an instance of `MtpErrorCantOpenDevice`

[mmokrejs]

Hi, this is maybe already reported by others, but I ran jmtpfs for the second time. I actually thought jmtpfs -u $DIR will unmount it. It does not but moreover, jtmpfs crashes.

$ jmtpfs -u /mnt/android/
Device 0 (VID=0b05 and PID=7772) is a Asus MemoPad 7 (ME572CL).
libusb_claim_interface() reports device is busy, likely in use by GVFS or KDE MTP device handling alreadyLIBMTP PANIC: Unable to initialize device

Maybe this helps.
