Hi!
[email protected] пишет:
Sorry for not clear about the kernel version, let me try again:
I have an ARM hardware board works fine with USB and MMC on kernel
2.6.11. Now, I've just upgraded it to kernel 2.6.22. The modules seem
loaded fine, please see following list, but neither USB nor MMC could
detect devices when a USB stick or SD card was plugged in (I enabled
module debug, but nothing printed out, no device node created in /dev).
It seems some processes were not running, but I can see usbd and mmcd
were running at following list, or what is missing?
K22 $ ps

746 root SW< [kmmcd]
775 root 644 S /bin/inetd -f
776 root 404 S /bin/sh
790 root 324 R ps
But does anything show up in syslog?
I understand that the devfs is no longer supported by the kernel 2.6.22,
but should the modules still be able to detect the devices? I manually
created nodes on /dev tree such as /dev/mmc /dev/scsi before building
and downloading to the target. Any clues please?
Please also make sure you've got decent udev running and properly
configured.

Thank you.

In the hope it helps.
