Hi, Johan, thank you for looking into this. I tested your patch, and it works! (5.4.11 and 5.5.0). I haven't performed extensive tests, but the card is again recognized as both playback and capture device. Thank you! Is this and acceptable solution and will this patch be integrated into the kernel? OTOH, you said: > Ok, so the device has a broken altsetting 3 for interface 1, where > endpoint 0x85 is declared as an isochronous endpoint, despite being used > by interface 2 as an audio endpoint: [...] > Note that the broken altsetting probably should be using endpoint 0x81 > just like the other altsettings for that interface,=20 I can't say I understand exactly what you're saying, but do you think it could be worth contacting the company and see if they are willing to fix this with a new firmware? Anyway, it's working now, thank you again. --
