Hi Cypress

Our customer asked us to tune the performance of the USB-to-I2C application

with CY7C65211 on Linux OS (x86_64).


  • And they passed  the following URL link to us.

Reduce Delay Observed During I2C Read Operations In USB-Serial – KBA227320



  • In the URL link, it said:

This will reduce the observed delay between the APIs to the order of thousands of microseconds,

which is significantly less than that produced with the cyusbserial.dll file present in the USB-Serial SDK.


  • But the solution is for Windows OS (*.dll) and there are not the source codes in the attachment.


  • We wish to port the solution to the Linux driver for the enhancement of the performance.

1-2-1) Could you send us the source codes of the solution (USB-Serial Library.zip) in the attachment?
