[cups] Epson R200 Ink Levels

[Ian Prideaux]

Hi All,

I still can't get this to work.

lsusb shows that the printer is:
Bus 001 Device 009: ID 04b8:0005 Seiko Epson Corp. Printer

/dev/lp doesn't exist, however, this does:
crw-rw-r-- 1 root lp 189, 8 Jun 29 18:17 /dev/bus/usb/001/009

If I stop cups, /dev/bus/usb/001/009 vanishes, so this is definately the 
correct usb path.


$ sudo strace -o ~/ink.out  ink -p usb -d /dev/bus/usb/001/009
produces the out file, which shows:

open("/dev/bus/usb/001/009", O_RDONLY)  = 3
ioctl(3, SNDCTL_DSP_SYNC, 0x7fff8329ee90) = -1 EPERM (Operation not 
permitted)
close(3)                                = 0


sudo strace -o ~/escputil.out escputil -r /dev/bus/usb/001/009 -i
produces an out file, which shows:

open("/dev/bus/usb/001/009", O_RDWR)    = 3
rt_sigaction(SIGALRM, {0x413d20, [ALRM], SA_RESTORER|SA_RESTART, 
0x7fe6f5617ff0}, {SIG_DFL, [], 0}, 8) = 0
alarm(5)                                = 0
write(3, "\33\1 at EJL ID\r\n", 11)        = -1 EINVAL (Invalid argument)
nanosleep({0, 10000000}, NULL)          = 0
write(3, "\33\1 at EJL ID\r\n", 11)        = -1 EINVAL (Invalid argument)
nanosleep({0, 10000000}, NULL)          = 0
<repeated lots of times>


For some reason, it looks like the programs don't have access to the 
character special device file, or the character special device isn't 
working properly.

Help?
