The issue is severe enough that the xHCI controller refuses= to re-enumerate the device until a full reboot (or cold plug with hub reset). = My laptop is a Lenovo Slim 7,=20 In some cases, the AKLOT interface locks up internally, requiring power-cyc= le or connection to another host to recover. --=20 You may reply to this email to add a comment.
