I wonder because the synchronous attempt to transmit URBs is way to slow for this. I more or less also have a userspace wrapper for video4linux2 and linuxdvb which also works with eg. libusb, libpci and works on Apple. On Linux it works with legacy applications by using LD_PRELOAD although I still need a fast data transfer link to the kernel for USB (which is not provided by libusb yet). I also have a driver for this already (DVB-C, DVB-T, analog TV, FM Radio USB Hybrid dongle). regards, Markus
