I am using NetBSD/i386 1.6.x with libexif-gtk-0.3.3nb7, gtkam-0.1.10nb7,
gphoto2-2.1.4, libgphoto2-2.1.4, and libusb-0.1.7 built from pkgsrc (with
the only change was getting rid of -DGTK_DISABLE_DEPRECATED from the gtkam
and libexif-gtk makefiles because I am using gtk2+-2.4.0).

dmesg tells me:

 uhub0: port error, restarting port 2
 uhub0: device problem, disabling port 2

The camera's case says "hp 435".

Running "gphoto2 --debug --camera "HP PhotoSmart 43x (PTP mode)" --port "u
sb:" --list-files" results in:

 *** Error ***
 An error occurred in the io-library ('Bad parameters'): Could not find USB
 device (vendor 0x3f0, product 0x7202). Make sure this device is connected to
 the computer.
 *** Error (-2: 'Bad parameters') ***

gtkam (which I tried first) also fails and pops up some windows saying:
"No cameras detected" when I click "Detect" (under "Select Camera").

When I select "HP PhotoSmart 43x (PTP mode)" and "Universal Serial Bus
(usb:)" (the only choice) it says "Could not initialize camera." and
"Could not list folders in '/'." in two windows titled "Bad parameters".

Does anyone use gphoto2 with HP 435 under NetBSD?

Or any ideas on how I can get this to work?

Thank you,

Jeremy C. Reed

p.s. I also sent same email to gphoto-user list.
