IO Gear GSR-202 / 202V / 203 cannot read newer CACs (Mac)

macos

Symptoms

Older IO Gear reader fails to read G+D FIPS 201 SCE 7.0 or Gemalto DLGX4 128Kv2 CACs.

Likely cause

Pre-May 2019 IO Gear units have firmware that does not support the newer card chips.

Fix

1. Read the reader serial number. Format OU95USC6201609 or newer = post-May 2019, supported. 2. If older, contact IO Gear about a warranty replacement, otherwise buy a newer compatible reader from militarycac.com/usbreaders.htm.
