Ubuntu 13.04 無法辨識 USB 驅動器

使用 Ubuntu 13.04（使用 Gnome 3），我的新 USB 記憶棒（詳情請參閱 dmesg/lsusb）不會自動顯示。情況：

• 驅動器未顯示在fdisk -l
• 驅動器在執行時確實出現lsusb
• 驅動器被 Windows 8 機器正確辨識

等了幾分鐘，看了reset high-speed USB device number 4 using ehci-pci我 dmesg 裡的消息，我決定拔掉我的棒，導致磁碟讀取失敗。

賣家首頁上也有人說他不能在 Linux、Android、他的電視和他的藍光播放器上使用這個棒。有人可以給我一個提示可能是什麼問題嗎？

我正在執行 Linux mint（基於 Ubuntu 12.04）並且遇到了類似的問題。這與我的 USB 記憶棒的插入位置有關。對於某些埠，電腦認為設備功率不足，因此它不會對其進行任何操作。在我的情況下，USB 棒已插入我的 USB 鍵盤。這是我所做的：

當我將它插入鍵盤上的 USB 埠時，它不會fdisk -l在鍵入時顯示： tail /var/log/syslog我得到：

Sep 19 09:11:55 taMereIV mtp-probe: bus: 6, device: 8 was not an MTP device

我提請您注意這一行：

Sep 19 09:11:55 taMereIV kernel: [ 1789.229213] usb 6-1.3: >rejected 1 configuration due to insufficient available bus power

因此，我將我的 USB 記憶棒直接插入我的筆記型電腦，現在， tail /var/log/syslog

特別是我的 USB 記憶棒現在出現在fdsik-l. 我猜想與 Win 8 相比，Linux 系統在確定為 USB 記憶棒供電需要多少電量時更加保守。

您可能只需要重新格式化整個分區。
