USB 3.0デバイスのEPリングに空きがありません

昨日mythbuntu 12.04をまったく新しいマシンにクリーンインストールしました。 ASRock Z77 Extreme4とIntelビデオチップセット、8 GB RAM。

私はこのドライバーのUSB 3の問題としてこれへのGoogle参照を見ていますが、私は在庫12.04を使用しているので、少なくともubuntuのバグ参照を取得したかったです。

Dmesg全体には次のものが含まれます。

[22822.772021] xhci_hcd 0000:00:14.0: ERROR no room on ep ring
[22822.772024] xhci_hcd 0000:00:14.0: ERROR no room on ep ring

私は、USBデバイスのセットアップに何も変更せずに2日連続でこの問題を抱えていました。 SBの再起動 は、私の場合、デバイスがカーネルによって検出されるように戻すのに役立ちます。

コントローラーのアドレスを決定します。

lspci | grep USB
00:14.0 USB controller: Intel Corporation 8 Series/C220 Series Chipset Family USB xHCI (rev 05)
00:1a.0 USB controller: Intel Corporation 8 Series/C220 Series Chipset Family USB EHCI #2 (rev 05)
00:1d.0 USB controller: Intel Corporation 8 Series/C220 Series Chipset Family USB EHCI #1 (rev 05)

この場合、それらは00:14.0、00:1a.0、および00:1d.0です。あなたとは違うかもしれません。

アドレスを使用して各コントローラーをバインド解除および再バインドします。

echo -n "0000:00:14.0" | Sudo tee /sys/bus/pci/drivers/xhci_hcd/unbind
echo -n "0000:00:14.0" | Sudo tee /sys/bus/pci/drivers/xhci_hcd/bind

私の場合、xHCIコントローラーだけでそれを行うだけで十分で、すべてのデバイスがlsusbに再び表示されました。分析中に、ほとんどすべてのUSBデバイスを取り外し、外部電源を使用して電源を入れ直しました。このような場合に推奨します。

明らかに、USBは機能しておらず、入力デバイスはすべてUSBである可能性が高いため、SSHなどの何らかのリモートアクセスが必要です。

あなたが書いているように、xhci_hcdはUSB 3.0のカーネルモジュール（ドライバー）であり、他のシステムでも同様の問題を引き起こすようです。あなたがここに投稿したものに質問がないので、おそらくあなたはバグレポートを提出するべきです。
