我在類似於Boundary devices氮氣6x板的定製freescale i.mx6板上運行Linux 3.0.35_4.1.0。USB無線桌面組合不斷重置「重置全速USB設備」
我遇到的問題是，當我連接「Microsoft Wireless Desktop 2000」的無線收發器加密狗時，鼠標間歇性工作，鍵盤根本無法工作。
收發器的HID ID是045E：0745
在終端的錯誤是：

我在以下帖子中找到了此問題的解決方案：http://forums.gentoo.org/viewtopic-t-902516-start-0.html和https://bbs.archlinux.org/viewtopic.php ？id = 91496 該問題涉及USB調度。內核配置選項「Improved Transaction Translator scheduling」（CONFIG_USB_EHCI_TT_NEWSCHED）是必要的。 – JBD1986
