Hello,

The firmware shared works fine.

I replaced the VID and PID in the firmware your shared with cypress VID and PID as I did not have your driver.

Please let me know if you are finding the issue with cyusb3 driver as well.

Best Regards,

Yatheesh

Hi Yatheesh,

    I am using an older controller(Pentium E5500).But there is no such problem on the i7 CPU. Computers similar to mine also have this problem. Recently, I revised the firmware with reference to the routine to solve this problem. Can you help me see if this is feasible?
