Dear all, I am facing a problem getting a USB digital camera to work with Linux.
It's a Nikon Coolpix 3500. It connects using USB and responds to the USB Mass Storage protocol, and appears as a VFAT file system. It connects to my laptop if I boot it in Windows 2000 (yes, I have a dual booting system :)), and I can just see it as an external device (F:), browse the file system, pick up images, and so on. Works beautifully. Which proves that the raw hardware at least is working fine. When I boot in Linux (kernel 2.4.20), I can see the kernel responding whenever I plug in the camera to the USB port. The usb_storage.o kernel module loads, recognizes the camera correctly. Here are lines from the kernel log: Jul 26 14:05:28 sm kernel: hub.c: new USB device 00:07.2-1, assigned address 6 Jul 26 14:05:28 sm kernel: usb-storage: act_altsettting is 0 Jul 26 14:05:28 sm kernel: usb-storage: id_index calculated to be: 89 Jul 26 14:05:28 sm kernel: usb-storage: Array length appears to be: 91 Jul 26 14:05:28 sm kernel: usb-storage: USB Mass Storage device detected Jul 26 14:05:28 sm kernel: usb-storage: Endpoints: In: 0xc4c48134 Out: 0xc4c48120 Int: 0x00000000 (Period 0) Jul 26 14:05:28 sm kernel: usb-storage: Found existing GUID 04b001100000000007515391 Jul 26 14:05:28 sm kernel: WARNING: USB Mass Storage data integrity not assured Jul 26 14:05:28 sm kernel: USB Mass Storage device found at 6 I also have SCSI support in the kernel, and I can see lines in /proc/scsi/scsi, telling me that the device exists and is /dev/sda. It tells me that the device is a Nikon with the correct model number and so on. So, definitely the SCSI subsystem of the kernel too is being fed correct information. So far so good. But I cannot mount /dev/sda1. Whenever I try, the mount command returns an error saying /dev/sda1 is not a block device. And yes, I'm trying this mount command as root, and yes, the mount point exists. What gives? What else should I try? I don't think my problem is specific to the Nikon 3500, so anyone using any camera with the USB Mass Storage protocol, please tell me if you've faced similar problems?
