Why would USB_Class_CDC_Send_Data not cause a USB_APP_SEND_COMPLETE

pbarada — Thu, 26 Jan 2017 22:37:12 GMT

Using in MQX-4.2.0.2 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!

Hi,

Please check the following threads and let me know if this helps!!
USB CDC on TWR-K60F120M and TWR-SER2 Board won't send certain values.
