Hi,

I have recently accquired a Reflecta RubyScan slide scanner. Works fine "on the 
other OS". Does 1800 dpi, 2556x1704 pixels.

Under Linux the results are not so good. "sane" does not like it at
all. "uvccapture-0.5" only works partially. It gives a lot of ioctl
errors and it works only with 1984x1328 pixels, which is 1400 dpi.

[r...@l6g0223j uvccapture-0.5]# ./uvccapture -v -v -x2556 -y1704
Using videodevice: /dev/video0

Any
advice to get this to work "correctly"? I am running CentOs-5.3 (Linux
2.6.18-164.el5) with current uvcvideo drivers. Please CC me, as I am
only reading the digest version of the mailing list.

On hotplug, dmesg shows:

usb 1-4: new high speed USB device using ehci_hcd and address 19
usb 1-4: configuration #1 chosen from 1 choice
uvcvideo: Found UVC 1.00 device USB Scanner. (115b:3100)

This is the output from lsusb:
