Hi Troels

no, it is USB2

No,I don't have access to another computer. But I have also Windows 7
installed. With Windows 7 and the Canon-software it works OK.
> *Does unit have ethernet connection / can you try that way?
Yes. With the ethernet connection the printer works. Thus the IP-address below
is correct.
But I cannot access the scanner.
xsane pixma:MG7500_192.168.0.3
results in the error message "illegal argument". Same thing with
scanimage --help -d bnjp://192.168.0.3:8612
Could you please tell me how to specify the device? Or do I have to enable IP-
support during compilation?
> *Excactly what is the last log line, before it hangs?
The log shows:
> [pixma] Sending time: '14/12/07 23:12'
> [pixma] OUT T=1.257 len=36
> [pixma] 00000000:eb 80 00 00 00 00 00 00 00 00 00 00 00 00 00 14
> [pixma] 00000010:31 34 2f 31 32 2f 30 37 20 32 33 3a 31 32 00 00
> [pixma] 00000020:00 00 00 51
> [pixma]
> [pixma] IN T=21.258 len=-9
> [pixma] ERROR: ETIMEDOUT
Therefore I assume the last line is "00 00 00 51"
The initialization sequence of the Canon software on Windows shows:
out:
55 53 42 43 F0 36 04 0B 00 00 00 00 00 00 06 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00
in:
55 53 42 53 F0 36 04 0B 00 00 00 00 01
55 53 42 43 F0 36 04 0B 12 00 00 00 80 00 0C 03 00 00 00 12 00 00 00 00 00 00
00 00 00 00 00
Sometimes the initialization with scanimage -T does not work either. I didn't
find out, when it works and when not.
