Hello, =20 First off, I am new to this list (I just subscribed today), but have done a few searches without finding anything related to my problem. I have a Fujitsu 3091 scanner attached via SCSI to a RedHat 9 Compaq Laptop. I'm running version 1.0.12 of sane-backends. We're creating a custom application in Java using the japi wrapper code provided with Sane. The problem is that I was getting "5/38/0: Invalid field in parm list" because of garbage in the fujitsu structure. I tracked it down to a problem in backend/fujitsu.c where the structure wasn't being initialized after being allocated. In the attachScanner function, I added the 2 memset lines after these two sections of code. This seemed to fix the problem. Let me know if you need more information. =20 if (NULL =3D=3D (dev =3D malloc (sizeof (*dev)))) return SANE_STATUS_NO_MEM; memset(dev,'\0',sizeof(*dev)); =20 ** if ((dev->buffer =3D malloc (dev->scsi_buf_size)) =3D=3D NULL) return SANE_STATUS_NO_MEM; memset(dev->buffer,'\0',sizeof(dev->scsi_buf_size)); =20 =20 As a side note, I've modified the japi wrapper code to be part of a package so it can be used by other java packages and would be willing to contribute that as well if you are interested. =20 Best regards, =20 Chris =20 ------_=_NextPart_001_01C3935E.2FDC604B Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable <html> <head> <meta http-equiv=3DContent-Type content=3D"text/html; = charset=3Dus-ascii"> <meta name=3DGenerator content=3D"Microsoft Word 10 (filtered)"> <style> <!-- /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {margin:0in; margin-bottom:.0001pt; font-size:12.0pt; font-family:"Times New Roman";} a:link, span.MsoHyperlink {color:blue; text-decoration:underline;} a:visited, span.MsoHyperlinkFollowed {color:purple; text-decoration:underline;} p.MsoPlainText, li.MsoPlainText, div.MsoPlainText {margin:0in; margin-bottom:.0001pt; font-size:10.0pt; font-family:"Courier New";} span.EmailStyle17 {font-family:Arial; color:windowtext;} @page Section1 {size:8.5in 11.0in; margin:1.0in 1.25in 1.0in 1.25in;} div.Section1 {page:Section1;} --> </style> </head> <body lang=3DEN-US link=3Dblue vlink=3Dpurple> <div class=3DSection1> <p class=3DMsoNormal><font size=3D2 face=3DArial><span = style=3D'font-size:10.0pt; font-family:Arial'>Hello,</span></font></p> <p class=3DMsoNormal><font size=3D2 face=3DArial><span = style=3D'font-size:10.0pt; font-family:Arial'> </span></font></p> <p class=3DMsoNormal><font size=3D2 face=3DArial><span = style=3D'font-size:10.0pt; font-family:Arial'>First off, I am new to this list (I just subscribed = today), but have done a few searches without finding anything related to my = problem.</span></font></p> <p class=3DMsoNormal><font size=3D2 face=3DArial><span = style=3D'font-size:10.0pt; font-family:Arial'>I have a Fujitsu 3091 scanner attached via SCSI to a = RedHat 9 Compaq Laptop.
