DP83TD510E-EVM: SPE+ line accidentally connected to EARTH_CDN completely destroys the board?

Part Number: DP83TD510E-EVM

Dear TI Expert,

During evaluation of the DP83TD510E-EVM the SPE+ and EARTH_CDN lines were accidentally connected with approx. 1kOhm resistance. Since that time I'm unable to establish link and also unable to communicate with USB.

Could you please give me some hints what to check/measure on the board? Because of the fact that it does not appear as an USB device, I unfortunately cannot use USB2MDIO.

Thank you for your response in advance,

 Peter
