<br>
I have got a Plustek U24 flatbet scanner I have been using since more or less the stone age, between 2007 and 2019 I regularely used it with Linux desktops and a 2007 MBP. Recently, I had to replace the MBP.<br>
<br>
scanimage on a devuan linux box works:<br>
<br>
scanimage -L<br>
device `plustek:libusb:001:009' is a Plustek OpticPro U24 flatbed scanner<br>
<br>
<br>
scanimage --version<br>
scanimage (sane-backends) 1.0.31-debian; backend version 1.0.31<br>
<br>
scanimage -d 'plustek:libusb:001:009' -T -v<br>
Output format is not set, using pnm as a default.<br>
scanimage: scanning image of size 202x150 pixels at 24 bits/pixel<br>

<br>
<br>
<br>
Trying the same, with the same device connected with a USB-C adaptor to the MBP M2 Max with macOS 13.5 (22G74), installed<br>
with macports:<br>
<br>
scanimage --version<br>
scanimage (sane-backends) 1.0.31; backend version 1.0.31<br>
<br>
scanimage -L <br>
device `plustek:libusb:001:001' is a Plustek OpticPro U24 flatbed<br>
scanner<br>
<br>
scanimage -T -d 'plustek:libusb:001:001' -v<br>
Output format is not set, using pnm as a default.<br>
scanimage: scanning image of size 202x150 pixels at 24 bits/pixel<br>
scanimage: acquiring RGB frame, 8 bits/sample<br>
scanimage: reading one scanline, 606 bytes... FAIL Error: Operation<br>
was canceled<br>
<br>
<br>
<br>
So the scanner is recognized, but somehow read fails while or after<br>
warmup - it takes a while before the error shows up.<br>
<br>
Any ideas? I wanted to do a bug report, but gitlab says my account is<br>
blocked and I have no clue what "contacting your gitlab administrator"<br>
means since there is no sensible contact information.<br>
