[ts-7000] /dev/i2c-0 and udev problem, TS-7530

["sanjuan34" <>]

Hi.I'm having trouble getting i2c setup on a TS-7350

Currently i2c_dev and i2c_core are loading at bootup, but udev isn't creating 
/dev/i2c-0. If I create it manually (mknod /dev/i2c-0 c 89 0), it still doesn't 
work. When I try to open it

fd = open( "/dev/i2c-0", O_RDWR );
 I get 

fd = -1 
Error opening /dev/i2c-0 : No such device

/dev/i2c-0 is definitely there

ls -l /dev/i2c-0 
crw-r--r-- 1 root root 89, 0 Feb 11 22:45 /dev/i2c-0


Now, I'm not sure if I'm doing this correctly:
to /etc/modules (at the top) I've added

i2c_core
i2c_dev
lincan hw=tscan io=0x150 irq=33 baudrate=1000

udev is creating /dev/can0 for the lincan driver, so I assume this is the right 
way to add modules you want loaded at boot time?

/etc/modprobe.d/aliases has an entry 
alias char-major-89-* i2c_dev

in /etc/udev:
% grep i2c *
compat-full.rules:KERNEL=="i2c-[0-9]*", SYMLINK+="%k"
compat.rules:#KERNEL=="i2c-[0-9]*",     SYMLINK+="%k"
devfs.rules:KERNEL=="i2c-[0-9]*",               NAME="i2c/%n"


Have I set something up incorrectly?

Thanks
-Jesse
