> +static DEVICE_ATTR_RO(usb3_hardware_lpm); Is my understanding correct that this sysfs entry is going to be read-only and there is currently no way to disable hardware LPM manually? I'm currently experiencing random disconnects of a ASMedia1051-based HDD enclosure. The issue is most probably the USB3 hardware LPM as pointed out by WD here: https://wdc.custhelp.com/app/answers/detail/a_id/9588/~/a-usb-3.0-drive-randomly-disconnects-and-reconnects-from-a-pc So far I haven't found a way to verify this hypothesis by disabling hardware LPM. -- 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
