I use STM32F429 USB HS Host library for UVC device.

Some UVC device has ISOC EP wMaxPacketSize=3072 or 5010 

Bytes.

I open endpoint type iso with msp = 5010 or 3072

Then I Set Interface Alternate and start stream with 

wMaxPacketSize = 

5010 or 3072

I use 

USBH_IsocReceiveData to receive data but USBH_LL_GetLastXferSize return max value 1020

and  data image I get is missing.

I think data missing because I can't receive iso package with wMaxPacketSize = 

5010.or 3072

Please me fix to receive it.

Thank you so much !!
