Can't connect on macOS: LIBUSB_ERROR_NOT_FOUND #121

wesleym · 2016-12-16T20:42:17Z

I built go-mtpfs from source but can't make it connect to my phone.

$ go install
$ $GOPATH/bin/go-mtpfs ~/mtp
2016/12/16 12:22:48 fatal error LIBUSB_ERROR_NOT_FOUND; closing connection.
2016/12/16 12:22:48 mount failed: no FUSE devices found

The debug output seems to show some MTP communication. The DeviceInfo retrieved doesn't seem obviously wrong. It's not clear why LIBUSB_ERROR_NOT_FOUND is printed first though.

$ $GOPATH/bin/go-mtpfs -debug usb,data,mtp,fuse ~/mtp
2016/12/16 12:24:41 fatal error LIBUSB_ERROR_NOT_FOUND; closing connection.

I think this is the message if OSX FUSE is not isntalled. Can you confirm that you have some FUSE FS mounted?

superbeef150 · 2017-08-16T18:02:08Z

Having similar symptoms here.
2010 MacBook OSX 10.11.6

Looks like the same output before/after installing OSX FUSE using osxfuse-3.6.3.dmg from their site, here's what I got after installing and rebooting:

Good news guys (seems to be outdated issue anyway), I had similar issue and found that calling mtp.Device.claim() before any communication solves the LIBUSB_ERROR_NOT_FOUND issue.

I don't know if it's portable between serveral OSes but anyway it's working on my Mac.
