毎度お世話になります。たけ(tk)ともうします。 Linuxの3.2のマシンと4.1のマシンとがあるのですが、 これにimationというメーカの外づけハードディスク（品番：IM80-UHD、 http://www.askul.co.jp/p/587725/）を繋げてみたところ、 （１）4.1のマシンでは、「kernel: usb 1-1: new full speed USB device using ohci_hcd and address 21」というのが２０秒ごとに/var/log/messagesに 書き込まれる。 （２）3.2のマシンでは、最終的に「kernel: usb.c: unable to get device descriptor」が書き込まれて、mountすべきポインタが分からない。 （３）どちらも fdisk -l しても、それらしいものは増えていない。 という状況です。何か手はありますでしょうか？ ＊ 前に付けていたlogitecのものがすんなり入ったので、甘く見ていた・・。 ---- （１）4.1のマシンでは、「kernel: usb 1-1: new full speed USB device using ohci_hcd and address 21」というのが２０秒ごとに/var/log/messagesに 書き込まれる。 [tk@EDiCube-03 tk]$ cat /etc/vine-release Vine Linux 4.1 (Cos d'Estournel) [tk@EDiCube-03 tk]$ [tk@EDiCube-03 tk]$ sudo cat /var/log/messages ・・・ Oct 16 12:42:26 EDiCube-03 ntpd[1994]: synchronized to 133.15.64.8, stratum=1 Oct 16 13:02:22 EDiCube-03 kernel: usb 1-1: new full speed USB device using ohci_hcd and address 21 Oct 16 13:02:43 EDiCube-03 kernel: usb 1-1: new full speed USB device using ohci_hcd and address 22 Oct 16 13:03:04 EDiCube-03 kernel: usb 1-1: new full speed USB device using ohci_hcd and address 23 ←２０秒おきに出ている。 Oct 16 13:03:25 EDiCube-03 kernel: usb 1-1: new full speed USB device using ohci_hcd and address 24 Oct 16 13:03:46 EDiCube-03 kernel: usb 1-1: new full speed USB device using ohci_hcd and address 25 Oct 16 13:04:08 EDiCube-03 kernel: usb 1-1: new full speed USB device using ohci_hcd and address 26 ←外したらでなくなったので、これに反応している。 [tk@EDiCube-03 tk]$ （２）3.2のマシンでは、最終的に「kernel: usb.c: unable to get device descriptor」が書き込まれて、mountすべきポインタが分からない。 [tk@EDiCube-01 tk]$ cat /etc/vine-release Vine Linux 3.2 (Ducru Beaucaillou) [tk@EDiCube-01 tk]$ [tk@EDiCube-01 tk]$ cat /var/log/messages ・・・・ Oct 16 11:39:17 EDiCube-01 kernel: hub.c: new USB device 00:01.3-1, assigned address 39 Oct 16 11:39:17 EDiCube-01 kernel: usb.c: USB device 39 (vend/prod 0x718/0x7288) is not claimed by any active driver.
