Our product based on cy7c68013a.

Most of them are Normally operating well. But some product did not be recognized about 2~3 times out of 10.

Power source, reset timing, i2c clk, data lines were good. However,there was someting very strange about i2c data voltage abnormal.

There was no pull up, or data transaction, but voltage level about 1.4v with pull down sometimes.(our voltage level 3.3v)

I haven't seen this symptom. Would you tell me how to debug this symptom? Wold you tell me how to solve this problem?

Can you please confirm if you are using the latest version of cyusb3.sys driver present in the FX3 SDK?
