I have gone through libusb, but i didn't find
isochronous transfer handling in libusb, because my
device supports isochronous transfer mode. So i
decided to write a kernel driver. Could you please
suggest me, how can it will be implemented in
userspace.

I compiled 2.6.3 on Redhat9.0. But hotplug didn't
detect my device.

What could be the changes in my driver for udev
instead of devfs on 2.6
