Re: [sane-devel] sane-backend 1.0.27 USB broken on Mac with Homebrew

2017-07-28 Thread schmo-fu

Yuri,

that's only part of the solution.

I tried
» brew reinstall
https://raw.githubusercontent.com/yurikoles/homebrew-core/sane-backends-1.0.27-1/Formula/sane-backends.rb
«

but it leads to error:
  curl: (22) The requested URL returned error: 401 Unauthorized
  Error: Failed to download resource "sane-backends"
  Download failed:
https://homebrew.bintray.com/bottles/sane-backends-1.0.27_1.sierra.bottle.tar.gz

»brew reinstall --build-from-source https://raw.github... « went fine.

I then also edited fxcouderts changes into my own Formula, but:
while »depends_on "pkg-config"« helps (as i wrote before)
but the added »=> :run« or »=> :build« don't make it any better.

The build-log shows »checking for USB... yes« now in any of the three
cases, but the scanner is still not detected.

This is a big step into the right direction, but not the whole way.


Greetings and Gruß,

 Hey Olaf and Yurii,

 thank you for your support, there is some progress:
 First i replaced usb-compat- with libusb-dependency in the formula.
 sane-backends compiled, but still no usb-support.
 Then i put »depends_on "pkg-config"« into the formula.

 And here we go:
 [sanei_usb] sanei_usb_init: initializing libusb-1.0
 [sanei_usb] sanei_usb_scan_devices: marking existing devices
 [sanei_usb] libusb_scan_devices: Looking for libusb-1.0 devices
 [sanei_usb] libusb_scan_devices: device 0x04a9/0x221c at 038:002 is not
 configured
 [sanei_usb] libusb_scan_devices: found libusb-1.0 device (0x05ac/0x8215)
 interface 0 at libusb:006:003
 [sanei_usb] store_device: add dn 0 with libusb:006:003

 Wow! This looked so good, until i realized that the device 0x04a9 "is
 not configured" (and the other one is just the
>> Bluetooth-USB-Controller).
 So »scanimage -L« tells me, that there is still no scanner.
 But this may be an unrelated issue, or isn't it?
 (The scanner btw. is a CanoScan LiDE 60. Switching back to sane-backends
 1.0.25 shows this:
 found USB scanner (vendor=0x04a9 [Canon], product=0x221c [CanoScan],
 chip=GL842) at libusb:038:002).

 Ah, here is the log:

[sane-devel] gscan2pdf v1.8.4 released

2017-07-28 Thread Jeff

gscan2pdf - A GUI to produce a multipage PDF or DjVu from a scan.

http://gscan2pdf.sourceforge.net/

Five clicks are required to scan several pages and then save all or
a selection as a PDF or DjVu file, including metadata if required.

gscan2pdf can control regular or sheet-fed (ADF) scanners with SANE via
libsane-perl, scanimage or scanadf, and can scan multiple pages at
once. It presents a thumbnail view of scanned pages, and permits simple
operations such as cropping, rotating and deleting pages.

OCR can be used to recognise text in the scans, and the output
embedded in the PDF or DjVu.

PDF conversion is done by PDF::API2.

The resulting document may be saved as a PDF, DjVu, multipage TIFF file,
or single page image file.

Changelog for 1.8.4:
* Cope with Tesseract 3.0.5 writing Page 1 instead of Page 0
  Thanks to Chris Mayo for the patch. Closes merge request #14
* Assume pixels/inch if the image doesn't know better. Closes bug #258
  (Tesseract 3.05.01: Warning. Invalid resolution 0 dpi. Using 70
  instead)
* Fix paragraph formatting in save as text output.
  Thanks to Chris Mayo for the patch. Closes merge request #16
* In preparation for future removal of libsane-perl frontend, change
  default frontend libsane-perl -> libimage-sane-perl, and similarly
  switch selected frontend on upgrade from older version. Assuming no
  major problems occur, support for libsane-perl will be removed in the
  next release.
* Fixed bug writing postscript file.
* + support for ghostscript backend due to apparent bug in tiff2ps.
* Round scan options with ranges to valid values before applying.
* Fixed bug updating list of option-dependent values. Closes bug #264
  (Effective resolution is 75 DPI despite selecting 600 or 1200).

Re: [sane-devel] Scanning With Nikon Coolscan LS40 / IVED

2017-07-28 Thread m. allan noah

You might try sane-backends 1.0.27, which includes the following
statement in its release notes:

Note 3: The Linux USB3 workaround which was added in version 1.0.25 is
now disabled by default. If you have difficulty using a scanner which
previously worked, or intermittent scanner availability, try setting
the new environment variable SANE_USB_WORKAROUND=1 before starting
your frontend.
