History: usbd_cd_cdc_ecm

This page describes all changes made to the usbd_cd_cdc_ecm package, USBD CDC-ECM Class Driver, since its release.

Version

2.5 (2017-09-21, 08:38):

usbd_cdcecm_set_mac_addr() did not work properly as it did not change USB string of MAC address.

2.4 (2017-08-15, 13:24):

Packet filtering used wrong MAC address and filtered all outgoing unicast frames when usbd_cdcecm_set_mac_addr() was called.

2.3:

- CDC-ECM lockup could occur as network interface was not initialized before reporting connected status.

- status of interface was not reported to USB host when it changed.

- packet loss could occur when no OS is used.

2.2:

Driver could not work with Linux hosts as Set Interface command was handled improperly.

2.1:

Class driver separated into two parts, depending on the new configuration option USBD_CDCECM_ACT_AS_NWDRIVER.
If USBD_CDCECM_ACT_AS_NWDRIVER != 0, then the class driver acts as a network driver: it can be interfaced to a network interface, typically required if the class driver is used with HCC's TCP/IP stack.
If USBD_CDCECM_ACT_AS_NWDRIVER == 0, then the class driver acts as a network interface: a network driver can be interfaced to it, typically required if the class driver needs to be used standalone or with a non HCC TCP/IP stack.
