Hello again,<br><br>I have an update: scanner works perfectly with Brother drivers only with USB2.0 (haven't checked 1.0) ports, and doesn't want to start using my 3.0 or eSATA ones. It's a serious problem for me, as I don't have any other data ports in my notebook.<br>
<br>Do you think it's a sane-, or a Brother- problem?<br><br>Thanks,<br><br>Pawel Chojnacki<br><br><div class="gmail_quote">2013/1/15 Pawel Chojnacki <span dir="ltr"><<a href="mailto:chojnacki.pawel@gmail.com" target="_blank">chojnacki.pawel@gmail.com</a>></span><br>

<br>
I am using 64-bit Debian Sid with 3.2.0-4-amd64 kernel. I had no
problems installing Brother DCP7030 printer with official drivers from
Brother's page, but I can't find any way to get scanner working. I've
installed sane 1.0.14-9 and libsane-1.0.22-7.4, brscan3-0.2.11-5.amd64 and
brscan-skey-0.2.4-0.amd64 packages, copied the lib64 libraries mentioned
in the Brother's FAQ.<br><br>
I've modified /lib/udev/rules.d/60-libsane.rules adding<br># Brother DCP-7030<br>ATTRS{idVendor}=="04f9", ATTRS{idProduct}=="01ea", MODE="666", GROUP="scanner", ENV{libsane_matched}="yes"<br>
# The following rule will disable USB autosuspend for the device<br>ENV{libsane_matched}=="yes", RUN+="/bin/sh -c 'if test -e /sys/$env{DEVPATH}/power/control; then echo on > /sys/$env{DEVPATH}/power/control; elif test -e /sys/$env{DEVPATH}/power/level; then echo on > /sys/$env{DEVPATH}/power/level; fi'"<br>
LABEL="libsane_usb_rules_end"<br><br>Default user pawel is in groups ld and scanner.<br>At the very end of /etc/sane.d/dll.conf, there's "brother3" line.<br><br>Now when I plug in my printer I can see dmesg:<br>

<br>The same happens with xsane and simple-scan, and when giving commands from root account. Switching to kernel 2.6.32-5-amd64, 3.5.0 or 3.7.1 doesn't help, either. Installing cups-driver-gutenprint and printer-driver-gutenprint changes nothing.<br>
<br>I know there are a few similar problems out there on the forums, but for me simply changing the access rights and groups does not work. Last time I got this scanner working was two months ago under freshly-updated Ubuntu 12.10. Now it doesn't want to start under the same Ubuntu LiveUSB, even though Sane and Sane-Utils versions are up-to-date. <br>
<br>Thanks in advance,<br><br>Pawel Chojnacki<br>
