https://bugzilla.kernel.org/show_bug.cgi?id=72761 This enclosure (with Hitachi 1Tb HDD inside in my case) have troubles with Gigabyte GA-H81M-HD3 USB3.0 ports. This MB has additional USB3.0 controller: --------- Chipset: 2 USB 3.0/2.0 ports (available through the internal USB header) 6 USB 2.0/1.1 ports (2 ports on the back panel, 4 ports available through the internal USB headers) VIA® VL805 chip: 4 USB 3.0/2.0 ports on the back panel -------- With kernel 3.11: 1.When I'm connecting Vantec to USB (chipset) it works but very unstable. It hangs and then disconnects while copying files. 2.When I'm connecting it to VIA chip ports it seems to work fine. With kernel 3.13.6 and 3.14-rc7 1.Same unstable behavior as in kernel 3.11 (with chipset USBs) 2.Do not works at all with VIA chip USBs. Enclosure and HDD is healthy (SMART is ok and it works flawlessly on another PC). Other USB3.0 flash disk (Silicon Power 32GB) works flawlessly on all ports. -- 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
