O.K., you now have extended logs..fine... comparing success/fail we see: -fail--- port 1 returns 0 pgood_delay=3D2000ms devnum=3D1 poweron: query_delay=3D2000 connect_timeout=3D3000 usb_control_msg: request: 0x0, requesttype: 0xA3, value 0x0 index 0x1 = length 0x4 Port 1 Status 311 Change 1 devnum=3D1 port=3D1: USB dev found usb_control_msg: request: 0x0, requesttype: 0xA3, value 0x0 index 0x1 = length 0x4 portstatus 311, change 1, 1.5 Mb/s ... STAT_C_CONNECTION =3D 0 STAT_CONNECTION =3D 1 USB_PORT_STAT_ENABLE 0 Cannot enable port 1 after 5 retries, disabling port. Maybe the USB cable is bad? cannot reset port 1!? -success---- port 1 returns 0 pgood_delay=3D2000ms devnum=3D1 poweron: query_delay=3D2000 connect_timeout=3D3000 usb_control_msg: request: 0x0, requesttype: 0xA3, value 0x0 index 0x1 = length 0x4 Port 1 Status 511 Change 1 devnum=3D1 port=3D1: USB dev found usb_control_msg: request: 0x0, requesttype: 0xA3, value 0x0 index 0x1 = length 0x4 portstatus 511, change 1, 480 Mb/s -- So we now know that when it fails, the issue consists of an underpowered = port1 of the USB-Hub ( what doesn't necessarily mean that the hub itself is the root cause) We see the values of query_delay / connect_timeout / pgood_delay=20 and some informative (device specific)problem descriptions ( as = comments) in the file :=20 common/usb_hub.c ...many possibilities to manipulate delays / max retries / force resets = or whatever, even the log message: "Maybe the USB cable is bad?" is = interesting ;-)... I would consider to "force" the King of USB to read this file contents = (usb_hub.c + usb.c): So consequently I quietly step out of the discussion again=20 and put HPS to CC :-) lol Regards Klaus
