But it's ok. I have hacked it by: 1. Detect more than a hour with the same voltage 2. When voltage is stable; stop the UPS monitor daemon 3. Run a usb reset program that I found in http://www.roman10.net/2011/05/04/how-to-reset-usb-device-in-linux/ 4. Start the UPS monitor daemon again Thanks for your help and attention man! o/ My best regards, - RF. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
