Port 4: 0000.0503 highspeed power enable connectĭevice Qualifier (for other device speed): ![]() Port 1: 0000.0503 highspeed power enable connect ![]() So after a full week I decided to go and seek professional helpĬode: Select all can't get debug descriptor: Invalid argument Putting dwc_otg.fiq_fsm_enable=0 leads to horrible distortion on both systems, and dwc_otg.fiq_fsm_enable=1 fixes that entirely on the LFS system and helps quite a bit on the busybox system, but doesn't really cure it. Besides from that there is no system-load or heavy IO on neither of the systems. This is really strange, since (to my understanding) the only elements involved are the same on both systems: The kernel drivers - snd_usb_audio - and the alsa-subsystem, which loads automatically upon usage. What is weird is that on my LFS system the USB interfaces work fine while on my embedded system, I get crackling noise. The kernels are self-compiled, using bcm2709_defconfig and only changing the preemption model to CONFIG_PREEMPT. I tried different kernel versions and they all have the same behaviour. For tests I only use arecord | aplay or jackd and have the rest turned off. The latter can even use brutefir with 4 channels. System load and IO are no issue: I can run jackd, netjack, brutefir and an audio-player when using a HAT or the USB 1 interface. USB 2 interfaces give me trouble, though. The system is working flawlessly with any HAT audio card as well as with my M-Audio Fast Track Pro (USB 1). This is working very fine for over a year now. I compile everything on the LFS and copy over only what I need. The embedded system is derived from a Linux From Scratch system. I am developing an embedded audio-streamer built around a busybox, which I set up myself. I am experiencing massive problems with USB DACs for a week now and I can't seem to wrap my mind around the problem. ![]()
