[sane-devel] BenQ Scanner 5150C

[Andrew Walrond]

Hello list,

I have a Benq 5150C USB scanner, which I have managed to get almost working.

Using the december 2nd snapshot of sane-backends, sane-find-scanner reports

	found USB scanner (vendor=0x04a5, product=0x2137) at libusb:002:007

scanimage -L reports

	device `snapscan:libusb:002:007' is a Acer FlatbedScanner40 flatbed scanner

(I am using this firmware from the latest windoze driver: u55v009.bin)

But if I try to scan with scanimage, it just hangs until I unplug the scanner.

A little googling turned up this thread from last December:
http://lists.alioth.debian.org/pipermail/sane-devel/2004-December/012758.html

Consequently, I found that if I apply this patch:

then scanimage seems to work:
	$ sudo scanimage > image.pnm
	[snapscan] Scanner warming up - waiting 3 seconds.
	[snapscan] Scanner warming up - waiting 3 seconds.

The image is recognisable, but has vertical colour bars all the way across it. 
(*For reference, a test scan is attached, so you can see what I mean)

I would dearly love to get this working; Can anyone suggest a way forward? 
I'll gladly help/test etc etc.

Thanks!
