Device shows up as unknown for linux/unix logs. What are some steps to troubleshoot/fix this issue? i got a response from RSA to delete the device and see if the device gets discovered correctly. if that doesn't work modify the configs manually. What about the injector? by the way, rsa also said that if we upgraded to 4.0 it should fix this issue as well. we upgraded to 4.0 about a month ago.
