USB3.0介面卡是Uptech UTB246

連接3.0讀卡機運作正常

這張轉接卡在Windows上是運作正常的
請問各位這是否是相容性的問題？

我的os是14.04

update
剛剛google了一下
這問題是不是一個還沒解的bug?
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/994248

今天再去試試這顆轉接器...發現如果是開機前先連接好那這顆硬碟就可以使用...
可是也不能熱插拔了, 我還刻意的只換硬碟不拔轉接器
系統也只能辨識換上去的硬碟, 接著還是 timing out command, waited 30s
除非我重開機了...

而且去做一下速度測試, 不管新舊硬碟速度居然都一樣不到40M, usb3.0下不該這麼差

請問有人知道原因是什麼, 有辦法自行解決嗎？ 謝謝 Q_Q

我很久以前就有發現這個問題了，我這幾個月以來Google只能確認Linux是最早支援USB 3.0這樣的相關描述，但我實際上遇到的是Linux對USB 3.0支援相當的有問題，其實不管用什麼裝置都會有問題，光碟機、鍵盤都一樣，只是你連接的裝置傳輸量越少問題越不明顯，我用的是Debian，如果Ubuntu最新的發行版還有這個問題，看來也許跟Debian系列略有關聯，但這個問題在Scientific Linux也同樣遇到，神奇的是CentOS就沒有問題，可見這兩者核心並沒有完全相同，我目前唯一的解法是改用CentOS，我認為這是核心技術問題，我在想可能跟USB 3.0的專利技術授權有關，但我不知道如何修好它，與你一起期待正解。
