Before you get too much in love with the idea of VueScan: I too thought this might be a quick and easy solution to a problem I had with scanners. To make a long story short, I tried VueScan, and it failed miserably with my Microtek X12USL scanner. I was finally able to get this scanner working to a fairly good degree with SANE. During my attempts to make this work I contacted the author, (and apparently the owner of the VueScan company), as his literature claimed that this scanner was supported. I quickly found out that he had, in fact, never tried this scanner, and he was less than helpful, and, quite frankly, very rude. As for the Open Source side, I think he needs to learn a bit about software and Open Source, as he seemed quite hostile about that, even though he takes liberally from SANE for his product. In looking at what he provides I believe that he is likely breaking the GPL already.. We tried a number of things he requested to gather information for him. At one point we had SANE and this scanner working together quite well, and I was trying to provide him with feedback to debug his product. He asked us to gather a number of logs, try various things, and report these back to him. After w while it was obvious that he was only paying lip service, and actually had no real intention of attempting to provide any support.. Here are a few of his more choice comments excerpted from our exchanges by email: "Unfortunately, I just can't spend time on this. I know that most scsi scanners work fine on Linux. I also know that the X12USL works fine on Windows (this is what I test on). There are a lot of different scsi drivers and scsi cards on Linux, and there are just too many different combinations of versions of things for me to be able to help with this. I'm quite sure that there's some combination of scsi card, scsi driver and Linux version that will work fine with VueScan 7.2.9 and the X12USL. Regards, Ed Hamrick" And: "> Whatever - 'xsane' works even if I had to hack it up a bit. The "even if I had to hack it up a bit" comment probably will give a clue as to what the problem is. I use the same sanei_scsi_open routine that SANE uses, and if the default version that comes with SANE didn't work on your system, that's the problem. Regards, Ed Hamrick" And: "> Perhaps you could tell me of a case where you saw it working, and with what > interface hardware? I don't know what scanners work with Linux, since very few people use the Linux version of VueScan (only about 50 people a day download it). However, I haven't gotten a bug report about a scanner not working on Linux in at least a month. Regards, Ed Hamrick" Take it how you will, but I can not recommend this product, or it's so-called support to anyone.. And his blatant admission that he is using SANE code in his product really seals it for me, at least: "I use the same sanei_scsi_open routine that SANE uses" Happy GNU Year!
