OK, I've reverted to standard unusual_devs.h, but I still have the patched

Actually it did apply OK (with some warnings about mismatched line numbers),
and it does make some difference, but not quite the desirable
one... /var/log/messages on stick insertion:Jan 30 18:12:28 quanxi kernel:

I notice that write protect on sda is off, but I can't mount sda1:
# mount -t vfat /dev/sda1 /mnt/stick
mount: special device /dev/sda1 does not exist
sdb1 can be mounted, read-only. Do you want the usbmon log?
