Hi Paul,
I tried to use these patches , but I see that all isoc OUT test does
pass, but it
fails with iosc IN.
I do use device as synopsys dwc3(in HS mode) and host as synopsys ehci
controller.
May be I will investigate it. But if you see something at a glance
then please let me know.
Regards
Pratyush

Hi Pratyush,
Please don't top-post.
Sry.. Will take care.
I did not test these patches with the dwc3 driver yet, nor with the
EHCI host, only xHCI. With xHCI, you need the ring expansion patchset
in order for testusb to work.
Also, I think there may be some issue with dwc3 and testusb, maybe
Felipe can comment on that.
Yes it seems that there might be issues with dwc3 driver while working
with isoc in. I also tried to use Audio gadget (recent uac2 patches
submitted by Jassi Brar).It is also net working. While same audio gadget
works with designware_udc.
I will debug it in detail and will get back.
Regards
Pratyush
