Hello! I have a Tevion MD9458 scanner which I would like to get to work with Linux. Apparently it is supported by SANE, and sane-find-scanner detects it correctly. However, when I try to access it with xsane or scanimage, I get the message:
open of device gt68xx:libusb:002:... failed: Invalid argument This happens when I am root or a normal user with appropriate permissions. The right number increases every time I try this, as somehow the file /proc/bus/usb/002/027 disappears and a new file /proc/bus/usb/002/028 appears, and so on. In syslog, there is also the message: usbfs: USBDEVFS_CONTROL failed cmd scanimage rqt 192 rq 1 le n 64 ret -84 And when I do an strace, there are a lot of lines that look like this: ioctl(3, USBDEVFS_CONTROL, 0xbfffc790) = 64 I'm using a 2.6.10 custom-built kernel and the current SANE and libusb drivers from Debian testing (Debian version numbers are 1.0.15-6 for libsane and 0.1.10-2 for libusb-0.1-4, whatever that means). USB works, and I can also access a digital camera with libusb. I hope this is enough information so you can help me with this problem. Thanks in advance. -- Sebastian Reichelt
