Title:
  Device name limited to 39 characters

Status in “digitemp” package in Ubuntu:
  New

Bug description:
  Recent udev in Ubuntu includes nifty permanent mappings for serial
  devices; for example, my 1wire master shows up as /dev/serial/by-id
  /usb-FTDI_FT232R_USB_UART_A800bZvc-if00-port0.  However, when I try to
  use this with digitemp:

  $ sudo digitemp_DS9097U -w -s /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A800bZvc-if00-port0

  Error, serial port '/dev/serial/by-id/usb-FTDI_FT232R_USB_U' does not exists!

  Attached is a patch bumping this limit from 39 (40 minus null) chars
  to 1023 (1024), fixing the problem:

  $ sudo digitemp_DS9097U -w -s /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A800bZvc-if00-port0
