我在kvm转发和打印方面遇到了问题(当我尝试打印一些东西时,WindowsXP来宾会使用BSOD )。我被建议将usb改为1.1版本。只有kvm适用于1.1版而不是2.0版的usb。我怎样才能在ubuntu os中的某些端口做到这一点呢?
USB ->佳能LBP 2900 (需要网络打印机)通过USB直接连接到Ubuntu服务器。这台打印机在printer里工作得很糟糕。所以我用winxp创建了客户vm,并将其转发到usb端口。Winxp识别此打印机并安装驱动程序。当尝试打印测试页面时-- BSOD。在VirtualBox中,所有的功能都很好。
它看起来像系统检测打印机作为usb2.0设备,但kvn只转发usb1.1max。所以我需要将USB2.0改为1.1

libvirt支持USB2已经有一段时间了:我建议升级http://www.linux-kvm.com/content/virt-manager-adds-support-usb2。
