Slide scanner woes - Minolta 5400
I'm in need of a little help.
I'm trying to sort out a friends PC, he is a semi-professional photographer, now caught in the "old hardware no longer supported in Windows 7 but reluctant to replace the hardware" trap.
He has a Minolta Elite Scan 5400 - it shows up in both Sane and VueScan, it swallows the slide tray and makes lots of noises and focuses - but, I cannot get it to do anything other than produce a solid black rectangle as the result of its scanning.
The system doesn't recognise it on firewire (I've never tried to use firewire on Linux) and I've tried 2 USB cables (after reading reports that these can cause issues).
I tried installing Darktable, but it doesn't see the scanner at all.
I tried Ubuntu Studio - it can see the scanner but then fails to connect to it at the vital moment.
The PC is running Mint 14 64bit - dual core 64bit AMD, ASUS mobo plus the usual assortment of peripherals.
