Android phone that use usb connect to a PC, open the rndis, then do iperf test between the phone and the PC. After a few of hour's test, the endpoint of rndis, ep1out, didnot receive a xfercomplete event that the gadget driver should receve after sent transfer command.
I try to enlarge event buffer size from 256 to 4096, also enlage the grxfifosize from delault value , but the issue remains.
The code is open souce from the synopsys that you can find at kernel/drivers/usb/dwc3/gadget.c
Thanks in advance.
