Hello Pierre, I tried the testprog under root. I think in root I must have the permission for the device. I controlled the the line 86 for the device and vendor ID. The vendor ID and the device ID are correct.
Every time the same error: Device not found I have an other question. For thus I programmed in the past only under ATARI ST 520 and Windows on programming environments and under Linux only some shell-scripts or ebuilds is there under Linux the possibility to do a line by line debugging like in Turbo Pascal or Visual Basic for applications? Can you give me some hint? I had in past errors that my E-Mail didn't reach you directly. Please let me know whether you read my mails from pierre at pirsoft.dnsalias.org or sane- devel at lists.alioth.debian.org? Last but not least I have a final question. Are you reachable maybe under IRC or VoIP? In special cases we may contact us directly, if you agree.
