Making your Minolta Dimage 7Hi work...

I just got myself a new Minolta Dimage 7Hi. Making it work under Linux was not too difficult:

The following works fine for gentoo-sources-2.4.20-r6 but should also work fine with any other kernel of the 2.4.x series.

First add to /usr/src/linux/drivers/usb/storage/unusual_devs.h the following lines:

UNUSUAL_DEV( 0x0686, 0x400f, 0x001, 0x0001,
"Minolta",
"Dimage 7Hi",
US_SC_SCSI, US_PR_BULK, NULL,
US_FL_START_STOP ),

Since this Camera is recognized as a USB-Mass-Storage-Device it is necessary to compile the following into your kernel:

Loadable Module Support: CONFIG_MODULES=y
CONFIG_KMOD=y

General Setup: CONFIG_HOTPLUG=y

SCSI support: CONFIG_SCSI=m
CONFIG_BLK_DEV_SD=m
CONFIG_SD_EXTRA_DEVS=40
CONFIG_SR_EXTRA_DEVS=4
CONFIG_CHR_DEV_SG=m
CONFIG_SCSI_CONSTANTS=y
CONFIG_SCSI_LOGGING=y

File systems: CONFIG_FAT_FS=m
CONFIG_VFAT_FS=m

USB support: CONFIG_USB=m
CONFIG_USB_DEVICEFS=y
CONFIG_USB_UHCI=m
(or CONFIG_USB_UHCI_ALT or
CONFIG_USB_OHCI, depending on your chipset)
CONFIG_USB_STORAGE=m

After you did this simply do a make dep clean bzImage and a make modules make modules_install and install the kernel as usual.
Then edit your /etc/fstab and add the following line:

/dev/sda1 /mnt/Dimage7Hi auto rw,noauto,user 0 0

In case you have other USB-mass storage devices or SCSI-disks installed you have to change the /etc/fstab to /dev/sdb1, /dev/sdc1 or the corresponding value.

Then create the mountpoint: mkdir /mnt/Dimage7Hi

If you want to have it very luxurious do an emerge sys-apps/hotplug. Then edit the /etc/hotplug/blacklist file to fit your configuration.

After you have done so simply establish th USB connection between camera and computer.
If you do a mount /mnt/Dimage7Hi you should be able to access your Dimage7Hi easily.

!!! You must not forget to unmount the camera before disconnecting the USB connection!!!

I can also recommend to install the GIMP Dimage COLOR plugin for all users of Dimage 5/7/i/Hi cameras you can find it under: http://dimage-color.sourceforge.net/ to help you to "downgrade" the color range from Adobe-RGB to normal RGB values and Mrwtoppm which can be found under http://home.swbell.net/dobroom/mintoppm/. This tool enables you either to convert Minolta DImage 5/7/i/Hi RAW format pictures (.mrw) into GIMP (.ppm) format on command line or as GIMP-plugin.

Greetings and enjoy your cam, Penulci

With Kernel 2.6.0-test4 compiling unusual_devs.h gives an error: 'US_FL_START_STOP'

I dumbass, I could simply mount the device without modify the kernel :oops:

The Problem was, that no usb device has been recognized due APIC Problems. I disabled APIC in the BIOS and now it works perfectly.
