Comment 22 for bug 306410

It's probably not a fault of your device that it doesn't work right away. The error code is the decimal version of error code 0x2013, which stands for the error PTP_RC_StoreNotAvailable. This is probably because of problems with the latest version of libmtp, you could try the command a few times directly after each other to see if it does pick it up after you've tried a few times. Sometimes it doesn't work right away.

Libmtp 1.0.x isn't as good as I've hoped; bug #424760 shows it still has some problems.
