A good datasheet is one step (on www.authentic.com datasheets seems to be provided). A second step is a software flowchart of how to put the usb commands in the right order. Also the choice must be made which type of driver will be made: 1. Kernel module 2. Userspace program (libusb, no isochronous mode support yet) For the userspace program a SANE backend is a possibility (scanner/webcam). For a example of a SANE vidcam backend (alpa status, uses libusb bulkmode) see http://gkall.hobby.nl/stv680-aiptek.html in SANE CVS /experimental/sanei_usb/ patched files for sanei_usb.c and sanei_usb.h are placed so the configuration, interface and altsetting nr. can be changed so all endpoints can be reached. -- -------- m.vr.gr.
