Any thoughts? In my opinion the cause is this instruction in ufm_start() function (see /usr/src/sys/dev/usb/ufm.c) if (ret & 0x1) return (EIO); Stangely and only for FM_START ioctl, the driver checks if the radio is in stereo mode so sometimes it returns EIO, but the radio plays all the same (at least mine :).
