Dear Sir,
This is shailesh malaviya from Ahmedabad.

I have one laser machine board having Cypress CY7c68013A-100AXC USB controller IC, used to transfer file from computer through USB.
When I connect the USB cable to Computer, The computer shows message ' USB device does not recognized'.
I tried other computer, but the problem remain same.
I have other same board, which works fine.
So, Please let me know, by replacing the CY7C68013A-100AXC will solve the problem?

Waiting for your reply.

Shailesh Malaviya,

Kindly check whether you have any ESD protection IC like IP4234CZ6.., This IP4234CZ6 is designed to protect Input/Output (I/O) USB 2.0 ports, that are sensitive to capacitive loads, from being damaged by ElectroStatic Discharge (ESD).

Usually this IC is placed between USB connector and CY7C68013A-100AXC. if yes check about it.
