why use the SA1110-USB-driver a static /dev/usbs... definition ???


Hello

I'm writing a device-driver on basis of the SA1110-USB-driver.
First I made a package without functionality. Then I tryed to get a handel
of my driver. It dosent worked. There was also no entry in the
..._install\lib\\libextras.a.

After houres of searching, I found, that the reason is the static definition
of the ..._devtab_entry. After removing the "static" key-word, my
test-program found his handels and does some pseudo inits...

The question for me is now, what is the reason for a static devtab?

The original source is:

"...\ecos\packages\devs\usb\sa11x0\current\src\usbs_sa11x0_data.cxx"

static CHAR_DEVIO_TABLE(usbs_sa11x0_ep0_devtab_functions,
   &cyg_devio_cwrite,
   &cyg_devio_cread,
   &cyg_devio_select,
   &usbs_devtab_get_config,
   &usbs_devtab_set_config);

static CHAR_DEVTAB_ENTRY(usbs_sa11x0_ep0_devtab_entry,
   CYGDAT_DEVS_USB_SA11X0_DEVTAB_BASENAME "0c",
   0,
   &usbs_sa11x0_ep0_devtab_functions,
   &usbs_sa11x0_devtab_ep0_init,
   0,
   (void*) &usbs_sa11x0_ep0);

Thanks for answers
