Using in MQX-220.127.116.11 on a twrk70f120m with a TWR_SER2 we're trying to send a bunch of data over USB CDC and we see that USB transmit/receive are working fine for a while (i.e. multiple minutes) and then things stop after a successful call to USB_CLass_CDC_Send_Data with no following USB_APP_SEND_COMPLETE notify event.
1) Have people seen the MQX EHCI device stack/driver exhibit this behavior?
2) What possible recovery methods could I try?
Thanks in advance!
