android-file-transfer error
 
If I connect my Android phone to the desktop (Slackware Linux) over USB cable, android-file-transfer works. If the phone stays connected for a while, android-file-transfer starts displaying an error at startup:

Code:
Device is busy, maybe another process is using it.

Close other MTP applications and restart Android File Transfer.

Press Abort to kill them or Ignore to try next device.
The fix is to unplug and plug back the USB cable.

Is there a purely software fix that does not involve touching the cable?

You may find out which process is using usb with 'lsof +D /dev/bus/usb'

I've had android do that using mtpfs or simple-mtpfs if:

You have a file manager open on your pc, showing an android directory. Android considers that to be busy. Or if you have a shell open, where you are in a mounted android directory.

The solution is to close whatever is viewing that directory on the android. Android is weird.

How about if you un-mount the android and then re-mount it, with whatever mtpfs software that you are using.

I do not understand this part. I am not typing any explicit mounting commands. This is my workflow:

- i have the desktop
- i have the android phone
- i have an usb-microusb cable
- i plug it into desktop and phone
- i start android-file-transfer

it works for a while then starts displaying the error above next times i start it

Look up the software that you are using and see what it does, what it's dependencies are.
