移動寬頻連接後立即斷開連接 - Crunchbang
幾個月來，我的移動寬頻 (GSM) 棒一直與 Crunchbang 合作。昨天就停了。當我插入它時，它會出現在網路管理器中，我可以連接到它，但是一旦連接它就會斷開連接。
大約 1.5 週前，我切換到 Liquorix 核心，並且棒也可以使用它，直到現在。切換回原始核心並不能修復它。
電腦：聯想U410
GSM 棒：Sierra Wireless USB 308
有沒有人遇到過這個並且知道如何解決它？
編輯：添加 dmesg 輸出

usb_modeswitch命令中的錯字sudo usb_modeswitch -v 1199 -p 68a3 -S該命令當時執行正常，但沒有任何效果。
在多台電腦和多個作業系統上測試設備後，寬頻棒似乎存在硬體問題。
