Looks like a current issue. From WP: A unit load is defined as 100 mA in USB 2.0, and 150 mA in USB 3.0. A device may draw a maximum of 5 unit loads (500 mA) from a port in USB 2.0; 6 (900 mA) in USB 3.0. If the disk needs more than 500 mA to spin up and start properly, it won't work on a USB 2.0 port unless you use the external power supply. > Also about usbus written that they are 2-port hub (probably > built into the motherboard). In the first four usbus is intel > UHCI root HUB, at the last - intel EHCI root HUB That kind of combination can often be found. My older home PC also had this kind of configuration (Intel EHCI, VIA UHCI). > "ls / dev / da *" finds nothing > "camcontrol devlist" outputs only DVD RW This shows that the disk isn't recognized by the OS, therefore not usable in any disk-related operation. > My hdd has an input for an external power supply, and it is > already connected to a second usb port. Also check the USB cable. Sometimes a "partially defective" cable causes this kind of trouble. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
