Greetings, The way that bcmxcp_usb reacts to and recovers from a USB cable unplug-plug appears to have changed significantly between 2.4.1 and 2.6.0. While I can see some improvements, bcmxcp_usb 2.6.0 does not appear to handle a USB cable unplug-plug correctly. Does anyone know if this has been fixed in subsequent releases?
Here are the details. When the USB cable between my server and my PW5115 UPS is removed, bcmxcp_usb reports DATASTALE (as it should) and continues to respond to PING (as it should). When the USB cable is reattached, bcmxcp_usb continues to report DATASTALE in response to DUMPALL even though lsusb indicates that the PW5115 is indeed connected and DATAOK is never reported in response to DUMPALL. If I restart the bcmxcp_usb driver with upsdrvctl then it recovers the connection to the UPS. The bcmxcp_usb 2.4.1 would not respond to even a PING while the USB cable to the UPS was disconnected, but when the USB cable was reconnected then it would begin responding again without the need to restart bcmxcp_usb. I am not suggesting that the driver be rolled back to this behavior, but I do need the ability to recover from a USB cable pull without restarting the driver. Thanks, Rich
