Hi all, I just purchased an HX stomp and when I connect to linux I get the following error message:

[ 322.404503] usb 1-6: new high-speed USB device number 13 using xhci_hcd [ 322.531804] usb 1-6: New USB device found, idVendor=0e41, idProduct=4246, bcdDevice= 2.00 [ 322.531806] usb 1-6: New USB device strings: Mfr=1, Product=3, SerialNumber=2 [ 322.531806] usb 1-6: Product: HX Stomp [ 322.531807] usb 1-6: Manufacturer: LINE 6 [ 322.531808] usb 1-6: SerialNumber: 3021888 [ 322.535789] usb 1-6: parse_audio_format_rates_v2v3(): unable to retrieve number of sample rates (clock 16) [ 322.535907] usb 1-6: parse_audio_format_rates_v2v3(): unable to retrieve number of sample rates (clock 16)

I have some kernel development experience but not a lot with usb so can someone point me where to start looking?

there was a previous discussion on the mailing list related to this by Jens Verwiebe (and other request for help). Here are the relevant patches/discussion

https://www.spinics.net/lists/alsa-devel/msg71459.html https://patchwork.kernel.org/patch/10113121/

If someone can help me I have an HX stomp here and time to do some debugging.

Also if someone from Line6 is listening would be helpful to have some hints.
