The ux_host_class_cdc_ecm not support process zero-length packet #26

Closed zxslzx closed 3 years ago

zxslzx commented 3 years ago

On linux we can use URB_ZERO_PACKET flag, but usbx doesn't seem to support similar operations.

xiaocq2001 commented 3 years ago

Is there any special reason to use URB_ZERO_PACKET ? USBX binds NetX and all network operations are handled by NetX or triggered by NetX operations, so I don't thing the API can be exactly same as linux API.

In USBX 6.1.4 the segmentation (ZLP) is already handled.
