Hi Jens, in my hx stomp with 2.82 firmware the USB id is the same and I'm not experiencing any glitch. Also some people on line6 confirm that the patch is working for hx stomp. If on helix the situation is different you should submit a patch.
Best Regards Nicola Lunghi

Back to the Helix once more .....
I already informed Nicola about latest Line6 firmware 2.8 ff changes.
All Helix devices seem to get a new product id due to the new core changes.
Additionally we have now an endpoint 5 for HID support ( applied dump ). Not sure what we can make out of this
cause a lack of investigation time. The audio endpoint descriptors are unchanged.
The problem with not working implicite feedback stays, so i still use my arbitrary 48005 Hz hack.
Without slight pop would ocure in audio, but still with this hack every 20 minutes i get a slight distortion which
is no surprise.
Can someone shed light here if an implicite feedback device should show the exact momentäry fequency ?
Should i see also the 16.16 feedback format ?
I looked through all code and 'am still stunned where the sync
fails.
Btw: i have also attached ioreg information from macOS if this helps someone to dig deeper. I dumped driverless
"usb compliant" mode here with integer outcome for a quick overlook.
This so far ... Jens
