Hi,

My camera is recognized (Nikon Coolpix S9100). If I try to list files (gphoto2 -l) I get the error: "Could not detach kernel driver of camera device". I don't know if it is gphot2 problem but I don't know where to find the solution. There is atachement of debug log. And below is the otuput on the console.

gphoto2 --debug --debug-logfile=/tmp/log.txt -l

libusb:error [submit_bulk_transfer] submiturb failed error -1 errno=2
libusb:error [submit_bulk_transfer] submiturb failed error -1 errno=2
libusb:error [submit_bulk_transfer] submiturb failed error -1 errno=2

*** Error ***
PTP I/O error

*** Error ***
An error occurred in the io-library ('Unspecified error'): Could not detach kernel driver of camera device.
*** Error (-1: 'Unspecified error') ***

thank you in advance

Sergiusz

  • 2.492746 libusb1(1): Detected defaults: config 1, interface 0, altsetting 0, inep 82, outep 00, intep 83, class 06, subclass 01

    outep should not be 00 (but 0x01)

    this was due to our libusb 1.0 support having a bug before libgphoto2 2.4.13, please upgrade to this versiuon.
