usb驱动与网络故障

2007-06-19 15:23

自从我上周五开始调试usb,我的网络开始变得很糟糕,今天才发现网络故障与usb的关系: 我的系统里面开启了usb的功能,然后插上U盘之后,我的PC机就不能ping通局域网络上面任何一台机器了. 为了查清楚到底是因为我一插上U盘,网络就会坏掉,还是因为我插上U盘,运行的程序引起的网络变坏,我就将Linux中的usb功能禁止掉,编译,运行,这个时候插上U盘,观察网络良好,( 刚刚写良好,网络就变坏,:<),现在只能说网络变坏的时间需要很长; 后来干脆就不插usb盘,程序运行一定时间网络一样变坏 然后我就只上电,只有bootloader在跑,看看情况如何?(待观察),结果是网络一直很好,是不是现在麻烦了,估计是系统其他地方引起的网络问题, 如果Linux中开启usb功能,一插入U盘,网络会马上变坏,所以我认为应该马上查查看插上U盘之后,程序做了什么动作? 此时插入U盘，出现： # usb 1-1: new full speed USB device using adm5120-hcd and address 2 usb 1-1: string descriptor 0 read error: -22 usb 1-1: string descriptor 0 read error: -22 usb 1-1: configuration #1 chosen from 1 choice ub(1.2): Error at GetMaxLUN (-2) 然后拔出U盘，出现 # usb 1-1: USB disconnect, address 2 再次插入U盘，提示： usb 1-1: new full speed USB device using adm5120-hcd and address 3 usb 1-1: string descriptor 0 read error: -22 usb 1-1: string descriptor 0 read error: -22 usb 1-1: configuration #1 chosen from 1 choice ub(1.3): Error at GetMaxLUN (-2) 这个错误出在drivers/usb/core/message.c 在修改FAT文件系统的字符集之后(由 (437) Default codepage for FAT   437－>936)，提示是： usb 1-1: new full speed USB device using adm5120-hcd and address 2 adm5120-hcd adm5120-hcd: Unlink after no-IRQ?
