Hi, I have a USB3 hard drive dock(Asmedia chip inside), it works fine by hotplug. But it can not be detected by coldplug (reboot with this device connected). The port status in dmesg during reboot are: [ 442.534809] xhci_hcd 0000:04:00.0: get port status, actual port 0 status = 0x2a0 [ 442.534819] xhci_hcd 0000:04:00.0: get port status, actual port 1 status = 0x2a0 [ 442.534903] hub 3-0:1.0: state 7 ports 2 chg 0000 evt 0000 [ 442.550736] xhci_hcd 0000:04:00.0: get port status, actual port 0 status = 0x340 [ 442.550747] xhci_hcd 0000:04:00.0: get port status, actual port 1 status = 0x2a0 [ 442.550823] hub 4-0:1.0: state 7 ports 2 chg 0000 evt 0000 It seems that the port which device connected is 0x340, but no "CCS(Current Connect Status)" bit. do you think this device is buggy? Btw, this device works fine under windows7 under same circumstance. BR, Jerome
