[sane-devel] CanoScan FB630P

[Dries Hoet]

Hey
I have a CanoScan FB630P parallel scanner and I finally got my scanner 
responding with the canon_pp backend on kernel 2.6.9 . But the data 
scanned is not received. Scanimage just sits and waits for eternity 
(scanimage > image.pnm), xsane receives no data. The scanner is 
recognized as should by scanimage -L: it says
    "device `canon_pp:parport0' is a CANON FB630P flatbed scanner"

sane-troubleshoot seems to be able to initialize the scanner, and starts 
scanning. The end of the log-file shows this: (I didn't paste the whole 
file because it is veeeeeeeeeeery long)

[canon_pp] -> ieee_transfer(24963)
[canon_pp] IEEE transfer (24963 bytes)
[canon_pp] <- (1024)
[canon_pp] -> ieee_transfer(23939)
[canon_pp] IEEE transfer (23939 bytes)
[canon_pp] <- (1024)
[canon_pp] -> ieee_transfer(22915)
[canon_pp] IEEE transfer (22915 bytes)
[canon_pp] <- (1024)
[canon_pp] -> ieee_transfer(21891)
[canon_pp] IEEE transfer (21891 bytes)
[canon_pp] <- (1024)
[canon_pp] -> ieee_transfer(20867)
[canon_pp] IEEE transfer (20867 bytes)
[canon_pp] <- (1024)
[canon_pp] -> ieee_transfer(19843)
[canon_pp] IEEE transfer (19843 bytes)
[canon_pp] <- (1024)
[canon_pp] -> ieee_transfer(18819)
[canon_pp] IEEE transfer (18819 bytes)
[canon_pp] <-


Setting force_nibble in canon_pp.conf results in scanimage not finding 
the scanner anymore.

Anyone knows how to solve this problem?

Thanks
