| |
Since I own a USB Pen Drive, which is perfectly working under Linux, I wanted to put a linux rescue system on it. But for some reason it wont work.
I linked in everything neccesary to boot from it: CONFIG_USB, CONFIG_USB_DEVICEFS, CONFIG_USB_UHCI, CONFIG_USB_STORAGE, CONFIG_SCSI, CONFIG_BLK_DEV_SD, CONFIG_EXT2_FS. I'm using kernel 2.4.15-pre4.
The problem is that the pendrive gets detected AFTER the kernel tries to mount the root fs. Checking init/main.c and entering some debug lines learns that the USB device gets detected when, in function init(), the console gets opened: 'open("/dev/console", O_RDWR, 0)'. Immediately after that, the 'init' program will be exec-ed. At the time of the 'open()' call, the kernel printk()'s "hub.c: USB new device connect on bus1/1, assigned device number 2", which is obviously the pendrive. It is correctly registered, and a SCSI disk is emulated. But too late..
Does anybody have a clue as to what the USB bus has to do with /dev/console?
Thanks for any help, Jos Nouwen.
