i-485 RFE, PLEASE CHECK FOR ME

I received one request for evidence.
"The documentation submitted is not sufficient to warrant favorable cosideration of your petition/application".

Attachment:

You appear to have neglected to submit any photo identity with your adjustment application.
YOu adjustment application much be accompanied by documentation establishing your identity. Therefore, submit a clear photocopy of a current photo identity document showing your picture, name and date of birth. Acceptable documents include passports, driver's licenses, state of national identification cards, or other identification issued by a government agency.

請問我隻要送一份copy of driver's license or passport or both. 他們沒有要別的. 請問我需不需要HR給我寫一封信. NIW,我自己申請的. 謝謝!!!
