compaq pro 6380电脑和hp laserjet 1020plus打印机，电脑使用的win7系统，有一台无法安装，在插上打印机usb连线时提示无法识别的usb，无法自动安装驱动，试了手动安装也不行。其他几套配置一样的都没有问题，把别的打印机拿过来安这台电脑上又能自动识别安装，没任何问题。把这个打印机装别的电脑上还是提示无法识别的设备。我看网上有说限制usb接口速度，改为1.1速率的就行了，但是bios没有找到能修改usb借口速度的地方，网上传的在设备管理器中修改的地方也行不通，要不就禁止了什么也识别不了，要不就发现无法识别的设备。我又把这个打印机放到一台老联想p4电脑上，居然能正确安装没一点问题，那个应该是2.0的usb口，现在请教有什么好的解决办法呢？？？？？</P>

如果你换过USB打印线的话我觉得还是打印机的接口板或者电源板静电造成的 如果是新机器我建议你去金牌维修更换 避免造成以后更麻烦 Wed, 09 Apr 2014 01:22:12 GMT
