That's not an ALSA problem, but most probably a firmware bug. A device with bNumConfigurations == 0 is invalid. Copied the linux-usb list.
I use ubuntu 12.04 and 14.04 and nothing, I have tested in windows and works well.
Could you follow the instructions in this document and generate a usbmon trace when connecting the device? I'd like to know whether the entire device descriptor is garbled. https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/usb/usbmon.txt Thanks, Daniel
