Which host OS are you testing ? I believe Windows's UAC2 driver doesn't support implicit feedback. |

Hi,
I'm using MIMXRT1170-EVK. I'm trying to use an implicit feedback endpoint.
I have a breakpoint here https://github.com/hathach/tinyusb/blob/master/src/portable/chipidea/ci_hs/dcd_ci_hs.c#L666
I have an Isochronous Asynchronous IN EP. When EP is declared TUSB_ISO_EP_ATT_DATA the breakpoint is regularly triggered, whereas if I declare it TUSB_ISO_EP_ATT_IMPLICIT_FB the breakpoint is never triggered.
where am i going wrong? Is this perhaps a bug?
Attached are the descriptor declaration files, of the two .h consider only usb_descriptors_implFb.h.
