I'm new to USB programming and I'm trying to get the usbvision driver to work with my Haugepauge USB WinTV-FM card.
The trouble I'm running into is in usbvision_probe() function. I also notice that many other USB drivers don't handle multiple config i.e.
if(dev->descriptor.bNumConfiguration != 1) return NULL
Sure enough, my card shows that dev->descriptor.bNumConfigurations = 4. So, what does it mean if it has more than 1 config? How does mine have 4?
I tried to bypass the check config statement but it resulted in undesirable effects, of course.
Any help to get me on the right track would be much appreciated.
