Hello! I`m

use

STM32_USB-Host-Device_Lib_V2.1.0

and

try to run the

USB

audio device

on

STM32F407VE + USB3300,

the device

is properly detected

and

any

audio player

starts

playing

, but the data

did not

come

as soon as

passed

initialization

EP1 (OUT)

are beginning to

be called

one after another

interrupt

Incomplete isochronous

OUT data transfers interrupt (IISOOXFRM in OTG_HS_GINTSTS),

data on the

EP1

as a consequence

do not come. 

Tried

a lot of things

to do

but nothing helps

:(

may

have any

or

especially when working

with

isochronous

points

in

HS mode with external PHY?

Hardware problems

virtually

rule

,

since

successfully

launched

VCP

in

HS mode,

the data is transmitted

normally

, the example

works fine.

I would be very

grateful for any

hint

, thanks in advance!

I got same problem with STM32F746ZGT6 with USB3320. And I notice that the offical USB AUDIO_Standalone example havn't implement it with ulpi phys, it only have USE_USB_HS_IN_FS, but in this mode, seems don't use externel phy at all。
