Thread: USB changes name automatically

-

hi all. im working gps receivers, , receive data , send data them work in ubuntu (progamming in c), , use serial port communication via usb.
open port, , after read data in infinite cycle.
if run 1hour, or 2 hours, device (in case usb0) disappear , communication receiver ends.
summarizing, when turn on pc, , if go filesystem, device usb0 there. start program (communicate gps receiver) , 1 hour, 2 hours or less, program automatically finish , output errno = 19, means "no such device". if go filesystem device appears there not usb0 usb1. dont understand why usb0 disappears , turn on usb1.

important, if me solve this..

thank
