USB 3ポートに接続すると、外部USB 3.0ハードドライブが認識されない
Iomega Prestige Portable External Hard Drive 1TB USB 3.0があります。
それは、USB 3.0ドライブとしてWindows 7で正常に動作します。
Ubuntu natty 64bit、2.6.38-8-genericでは検出されません。
fdisk -lはそれをまったく見ることができません。

ファームウェアがLinuxなどと互換性がない可能性があると思いましたが、partedmagic（2.6.38.4-pmagic）のライブイメージを起動すると、ドライブが正常に検出され、マウントしてusb 3.0の速度（少なくとも、USB 2ポートに同じドライブを接続することで得られる速度は2倍になります）。
partedmagicのdmesgは、SuperSpeedエンドポイントがないことについて何か言っていましたが、これは以前のubuntuのdmesgで見たエラーでした。

まあ私は何が間違っているのか分かりませんし、これまでのところグーグルやフォーラムからあまり運がありませんでした。同様のエラーメッセージと問題のみを抱える人々との多数の未回答のスレッド。
うまくいけば、ここの誰かが私を助けたり、正しい方向に向けたりすることができますか？
