The program gets this FF14 error when it tries to allocate resources for isochronous transfers.
Like Lars already said: isochronous transfers are not yet supported by the ArcaOS 12.x USB drivers.
Try and use the ArcaOS 11.17 drivers instead. Or use the latest Lars Erdmann USB driver set.
Ok, thanks i'll give it a try
Did you try and use your webcam with the ArcaOS 11.17 drivers? Did it work with these?
Did you try and use your webcam with the Lars Erdmann 10.234 drivers? Did it work with these?
Hi Wim,
According Andy's update, isochronous is supported.
How to make it work please using AN latest build ?
Thanks
Regards

As I wrote at the top, I did a try with your usbecd driver and it didn't work too. You told me to remove it, So I did.
No, I can not go backward to ArcaOS 11.17 (it requires to backward on all usb drivers and this is not possible to maintain my production (and only system) system fully operational)
This system is with AN supported drivers according support contract, those from Lars aren't supported.
There are no elements telling a failure into AN drivers ! So, no ticket can be opened now for a problems outside AN products
what else please ?
Some information about the webcam seen by the driver.
