Short: VHI driver for Logitech Quickcam Express Author: Andreas Barth Uploader: anonymous aminet net Type: driver/video Version: 0.2 Architecture: m68k-amigaos >= 3.0.0 Distribution: Aminet Important! ---------- This software is free to use but comes with absolutely no warranties. Use it at your own risk! It works for me, and if you find it useful at all, hopefully also for you. What is it? ----------- A VHI driver for older Logitech Quickcam Express USB cameras. Currently the models supported are (USB vendor ID/USB device ID): - 0x046d/0x0870 (the one I have) If you have a currently not supported model, then support for it could maybe added. Let me know the IDs and we can see ... What is required to use it? --------------------------- You need: - an AMIGA with a Deneb card, because isochronous transfer is used - the Poseidon USB stack, because the driver relies on it - one of the supported camera models How to install it? ------------------ Copy the file "quickcamexpress.vhi" to the LIBS:vhi folder. How to use it? -------------- Choose the driver in the video software that can use VHI drivers and follow the instruction of that software. What does work? --------------- For the supported camera models your video software should be able to get images from the camera. Known problems! --------------- During testing I had random crashes while capturing was active and other programs did access drives connected the CyberSCSI of my Cyberstorm MK2. It turned out, that this relates to the SCSI Handshake setting set with the UnitControl program. It was set to 15. But with 8 the chances for this problem to occur seem significantly reduced. Using the Deneb DMA or PIO driver does not seem to matter. Why does it exist? ------------------ Sometime ago I thought of writing a driver for this old camera I had. But I could not get any documentation on the bridge chip used in it. So it took very long until I finally started. With the help of USB analyser, the Linux sources and the Poseidon author (thanks Chris) I have now a working driver for my camera written basically from scratch. And I am happy, that I got this working.
