Hi everyone,
I'm experiencing some problems getting my digital camera (Sony Cybershot
DSC-T1) to
interface with the USB system under FreeBSD RELENG_5.
I've tried setting my camera into normal mode and tried to use it as a umass
device, but no /dev/da* device is created so there's nothing for me to
mount. umass0 entry is created though.
Setting my camera to PTP mode, I tried using gphoto2 to get pictures, or
even just simply listing the files on the camera, fails with operation timed
out. The offending portion being
0.109944 gphoto2-port(2): Setting timeout to 8000 millisecond(s)...
0.110027 ptp(2): PTP: Opening session

I've read on google and other places where this has been resolved for some
cameras, but it doesn't seem to work with mine. I'm willing to help debug
the code. I've tried looking into the file bsd.c that comes with libusb and
found that gphoto2 stalls around the place where the read takes place
(obvious). I'm not really sure what else to check since it's writing and
it's being accepted by the camera, but the read is just failing. I'm
inclined to think it's a USB issue since gphoto2 sends the exact same bytes
to the camera on my linux machine and it works perfectly there.
I have
gphoto2-2.1.4_1
libusb-0.1.7_1
Thanks all,
Frank
