geniusmen

各位侠女侠士：
  我刚刚闯荡LINUX江湖，涉世甚浅，很多LINUX的江湖规矩还不是太懂，希望各位出手相助！小弟在此谢过！如果你路过，也请支出个一招半式，小弟以后我也能在LINUX江湖中独挡一面啦！！
  小弟在LINUX下编写一个MODEM驱动，虚拟了一个USB口，能写入AT指令什么的，但是当我联上网下东西的时候，这个虚拟口就挂了！！！血都不流，真是杀人于无形，真是急煞我也！！！不过我侦查了现场，发现留下一字条
上面写道：usb-uhci.c: interrupt ,status 3!
   请问问题出在哪？ 是USB-UHCI他杀？还是我的虚拟端口自杀？网各位帮我支支招！！！！

lz 寫的話，真的是行走江湖人才啊。

多半是自杀，肯定是驱动程序的毛病，可以用printk查查，看看到底死在哪了

geniusmen

呵呵，楼上的果然是侠骨柔肠，谢谢指点，俺一定要追查出死因！！！

  希望大侠走LINUX江湖越来越顺利，打个喷嚏也能威慑论坛四方！！
