Ketika akan memindahkan data dari HP android ke laptop melalui thunar, menunggu lama dan berujung gagal. Setelah dicek dengan mencoba melalui jmtpfs

$ jmtpfs
Device 0 (VID=0e8d and PID=201d) is a MediaTek Inc Elephone P8000.
error returned by libusb_claim_interface() = -6LIBMTP PANIC: Unable to initialize device
terminate called after throwing an instance of 'MtpErrorCantOpenDevice'
  what():  Can't open device
Aborted

Ada masalah di libusb. Coba reinstall libusb

# slackpkg reinstall libusb

Alhamdulillah sukses.
