2.6.7-bk21没有/dev/sda1设备

加载usb设备的时候说/dev/sda1不是有效的块设备

应该修改内核配置的哪部分？

thx

U盘被识别为scsi设备。你的内核配置文件里没有搜到scsi相关的选项～
经测试，插入U盘后以下5个模块被加载，其中floppy应该不是必须的，插入U盘的时候也检测软驱了(为什么？) 至于每个模块对应内核哪个选项我还不清楚……
等编译2.6.8的时候查一下

[code:1]floppy                 55568   0  (autoclean)
sg                     35468   0  (autoclean)
sd_mod                 13424   0  (autoclean)
usb-storage            72800   0
scsi_mod              103144   3  [sg sd_mod usb-storage]
[/code:1]

应该还有个usb-core，可能你编译进内核了
