[javax-usb-devel] Using isochronous tranfers ?

[Aurélien GODIN]

Hello,   I have some trouble using the javax.usb package. I succeed in lauching the Usb services, finding the devices and opening the corresponding pipes. If these devices use interrupt transfer mode, everything's ok. But I don't succeed in retrieving data when the device uses isochronous transfers. Can somebody help and explain me what is the differences with the other modes and how to collect the data ? (a few lines of code would be much appreciated...). The device which is connected is a Labtec Webcam (352x288 images) : I have noticed that two pipes are open, one functioning in interrupt mode (what is its use ?) and the second one using isochronous mode but I have absolutely no idea how to handle them !   Thank you for your help and your comments,   Aurelien   PS : Maybe this mailing list doesn't aim to answer such questions but I didn't find any FAQ section. So, sorry if that was not the appropriate way to submit my issues...
