[Bug 155788] Re: KDE blocks digital camera detection as usb-scsi disk

[GrahamGRA]

I had a similar issue. Except I was bogged down with this from dmesg

graham at salbutamol:~$ dmesg | tail
[ 7675.049783] usb 5-1: usbfs: USBDEVFS_CONTROL failed cmd kio_kamera rqt 33 rq 102 len 0 ret -110

It would hang on 'waiting for device to settle before scanning' and then
print the error about kio_kamera. That said... for me I don't think the
kio_kamera command exists.

$ kio_[TAB]
kio_http_cache_cleaner     kio_system_documenthelper
kio_media_mounthelper      kio_uiserver
kio_media_realfolder       kio_umountwrapper

Anyway... from what I can tell it was trying to mount my camera (Nikon
Coolpix 5600) with PTP because PTP worked with my camera. I removed this
from '/usr/share/hal/fdi/preprobe/10osvendor/20-libgphoto2.fdi'

   <match key="usb.vendor_id" int="1200">
    <match key="usb.product_id" int="302">
     <merge key="info.category" type="string">camera</merge>
     <append key="info.capabilities" type="strlist">camera</append>
     <merge key="camera.access_method" type="string">ptp</merge>
     <merge key="camera.libgphoto2.name" type="string">Nikon Coolpix 5600 (PTP mode)</merge>
     <merge key="camera.libgphoto2.support" type="bool">true</merge>
    </match>
   </match>

And it mounted correctly as a mass media device. I think it may be
possible to have it mount correctly by changing camera.access_method to
mass media but I don't know what to put in place of ptp.
