I still see legousbtower registered in drivers/usb/misc/legousbtower.c.
Are you sure about these changes? Also, do the names in this document
match the names registered with sysfs (new mga_* stuff etc)?
I found a few sysfs entries that differ from devices.txt:
# misc devices
# 183 = /dev/hwrng        Generic random number generator
KERNEL="hw_random",     NAME="hwrng", SYMLINK="%k"
# 219 = /dev/modems/mwave MWave modem firmware upload
KERNEL="mwave",         NAME="modems/%k"
# 169 = /dev/specialix_rioctl Specialix RIO serial control
KERNEL="rioctl",        NAME="specialix_rioctl", SYMLINK="%k"
# 167 = /dev/specialix_sxctl Specialix serial control
KERNEL="sxctl",         NAME="specialix_sxctl", SYMLINK="%k"

Hm, this is just wrong.  As I recall, LANANA is in charge of the major
numbers, but for the USB major, the USB developers have been assigning
the USB minors.  This patch just made the file different from what is
currently present in the kernel.

Should I just submit a patch to LANANA to update the USB minors for
their copy so this doesn't happen again?

I'll also fix this up in mainline in the next round of USB patches...

thanks,

In general the policy has been:  submit to LANANA any changes to 
devices.txt, which they maintain.

So, they are the maintainer of major numbers, but also the maintainer of 
devices.txt.

Yes please!. Since the devices file at lanana.org is the one being merged into
the one in the kernel tree, please send future updates to lanana and it'll go
in that way.
