But if we do so, we should at the same time get rid of all the queue management. If you compare the Linux part of sanei_scsi with that for other operation systems, you will note that the code is much simpler, mostly due to the fact that these OSes all use Ohhh yes... that would greatly simplify sanei_scsi. It's been fun to workaround the async code to get the ioctl in sanei_scsi :] ;) a simple ioctl instead of the write/read logic. OK, this would also mean to change a bit more in sanei_scsi, especially it would mean that the check for the availability of the SG_IO ioctl would be moved from run time to compile time. I think we can even get rid of the old SG interface entirely. SG_IO exists in Linux 2.4 too, so it should be safe. I must admit that I am one of these persons who cannot throw away anything... But you are right: Doug Gilbert wrote the SG3 interface in the late 90ies (IIRC, the first versions were available even for 2.2.x kernels), so keeping the old interface would be useful for very few people, if any. But I am quite surprised that your Microtek scanner is so much faster with the ioctl is than the current implementation. When Doug Gilbert had It can be due to changes in the microtek2 backend too. Honestly, I haven't bothered to check :) implemented command queuing for the SG driver, I noticed a considerable performance gain for the Sharp JX250 scanner. The latency between the end of a SCSI command and the start of the next command (from the viewpoint of the scanner) is lower, if the command has already been issued by the application, so the kernel can start the next command immediately, without a context switch to the application. On the other hand, this was at a time, when processors had clock speeds of 200 or 300 MHz. With modern processors, the latency is small enough even if kernel level queueing is not used. The latency here seems low enough, and this machine is an SGI Indigo2 R4400SC 200 MHz w/256 MB RAM and an asthmatic SCSI controller (under Linux, at least, because we don't have the specs ...) The effects of longer latency times seem to depend heavily on the scanner models. The Sharp JX250, a moderately fast model, probably with only a tiny internal buffer, seems to suffer more than many other devices... Abel

[sane-devel] Firmware for Epson Stylus CX-1500?
Hi everybody, I'm using an Epson Stylus CX-1500. I can scan image from it with snapscan backend. However, the image is green, no red, no blue.

Finally, he also read some info found on the sane archive, but it still doesn't work. Suggestions are welcome, and I will translate and send it fwd to him.
