gphoto2 doesn't detect Nikon D100

NaN

As per the subject the problem I have is that gphoto2 does not detect my Nikon D100 camera. The problem appears to be that the product ID in the database of cameras does not match. gphoto2 thinks that it should be Vendor ID 04b0, product ID 0402, but using usbview the product ID is reported as 0401.

I changed this in /etc/hotplug/usb.usermap so now when I plug the camera in an entry is created for it in /proc/bus/usb/001. However gphoto2 --auto-detect does not find it. If I specify the bus and camera model gphoto2 reports:
"Could not find USB device (vendor 0x4b0, product 0x402)"

Where else do I need to change something to define the D100 product id as 0401, not 0402 ???

Also I notice that hotplug is not finding a driver for it, and, therefore is trying to load the usb_storage module. This doesn't work with the D100 which has to be used in the PTP protocol mode. Perhaps this is caused by the same problem? (i.e. not being able to match the vendor and product IDs with the PTP driver?)

I believe USB is working fine and hotplug is installed with the right permissions. I have searched these forums, hotplug and the usb howtos for any clues, now I'm running out of ideas.

Any help appreciated. TIA

I would encourage you to get a CF reader. They are really cheap and the convenience is fantastic. Pop for the 30 bucks and save the wear and tear on that beautiful camera.

I have always planned to get an external CF reader too, though not necessarily to save on wear and tear, since it will mean swapping the CF card in and out of the camera as opposed to plugging in the USB cable.

Having researched this further, I notice that my camera has come with firmware version 1.01, whereas the box listed it as being shipped with version 2.00. :evil:

Perhaps this is the difference. I'll arrange and upgrade and see if that makes a difference.

I don't know the D100, but other Nikons I've seen can simply be mounted like:
mount -t vfat /dev/sda1 /mnt/camera

I tried. The usb-storage driver was unable to retrieve any directory information. I can access the card (IBM microdrive) using the IBM microdrive PC card carrier plugged into my work laptop running win2k

In all fairness, the gphoto2 documentation for supported cameras listed the D100 as supported only in PTP mode.

Here's an update for anyone else who might be interested.

I've had my camera firmware updated to V2.00 and now it works - that was the final problem all along.

David.

PS. I've also got a compact flash reader that reads the IBM microdrive now. That is a better solution for transferring lots of images, but it's useful to have either method working.
