Hello @brucecairo. We appreciate you taking the time to post on our Community forum.
We are sorry to hear that you experienced difficulty with our PEX4M2E1. The PEX4M2E1 is a pass-through device in nature. We recommend ensuring the latest BIOS is installed on the computer and ensuring that the PCIe slot itself is not disabled within the BIOS. If the issue continues, we have opened case # 484-1255844 and encourage you to contact us at support@startech.com. Please include the case number and ‘community post support’ in the subject line. Thank you in advance, and we look forward to hearing from you!
