I'm trying to access a USB digital camera under RedHat null Beta2 The Camera information is as follows: USB Epsilon 1.3 (Digital Dreams) Resolution 1600 x 1280 pixels Image sensor CMOS LCD Screen 1.5" colour TFT Internal memory 8MB NAND Gate Flash External Memory Build in Smart Media card slot Viewfinder Optical Digital zoom X 4 Image capacity (with build in memory) 1600x1200 - 20 1280x1024 - 29 640x480 - 121 White balance Auto/Day/Shade/Bulb/Fl Exposure Auto/Manual Image format JPG, AVI (through software) Computer interface USB Power control Auto off (10 seconds) I'm running a standard kernel 2.4.19-ac2 with USB Mass Storage degugging Information.and also RedHat's 2.4.18-12.5 (the below messages was taken for the 2.4.19-ac2) When I plug it in its detected as: [root@stimpy mark]# usb.c: USB device 2 (vend/prod 0x733/0x1310) is not claimed by any active driver. Vendor: Model: 1.3M DigitalCAM Rev: 1.00 Type: Direct-Access ANSI SCSI revision: 02 Attached scsi removable disk sda at scsi1, channel 0, id 0, lun 0 SCSI device sda: 16384 512-byte hdwr sectors (8 MB) sda: test WP failed, assume Write Enabled sda1 Which means that the kernel has seen it and its being treated as a mass Storage device, thus treated as a SCSI device. So I also ran cdrecord -scanbus and that listed the device as well. scsibus1: 1,0,0 100) ' ' '1.3M DigitalCAM ' '1.00' Removable Disk After reading several pages on USB and Mass storage, I have found out how I should be able to access it The following Kernel modules that are relevant to this device are loaded as below: vfat 11356 0 (autoclean) fat 36888 0 (autoclean) [vfat] sr_mod 16248 0 (autoclean) usb-storage 102352 0 usb-ohci 19528 0 (unused) usbcore 69888 1 [usb-storage hid usb-ohci] aic7xxx 123444 0 sd_mod 13104 0 scsi_mod 99716 4 [sr_mod usb-storage aic7xxx sd_mod] The file system on the camera is FAT (this can be accessed by VMware running on this Box, as a removable device (which is running a Virtual WinXp O/S) through the USB port using the drivers for windows supplied by the manufacturer) mount /dev/sda /mnt/camera and /sbin/modprobe fat && mount -t fat /dev/sda /mnt/camera I've also tried vat, auto, autofs and /dev/sda[0-10] as well. Also running the following, it cannot access the device either: [root@stimpy dev]# dd if=/dev/sda of=/dev/null bs=1k count=1 dd: reading `/dev/sda': Input/output error 0+0 records in 0+0 records out It seems it cannot find a partition table on the device, in WinXp I can happily right click and create folders on the camera, It can also Identify the amount of space on the device 8MB, when first plugged it. And I have also tried the following as well: [root@stimpy mark]# cat /dev/sda | file - cat: /dev/sda: Input/output error standard input: empty Please see below the output of dmesg -n 9, with USB Mass storage debugging turned on (sorry for the large amount) ---------------------- cut ----------------------------- hub.c: USB new device connect on bus1/1, assigned device number 2 usb.c: USB device 2 (vend/prod 0x733/0x1310) is not claimed by any active driver.
