Hello,

Any plans of releasing a new driver for the FX3_Driver? We are currently using v1.2.3.14.

With the recent windows updates we are seeing an issue that most of the times after the event OnDeviceAttached we need to wait a bit more in order to access the CyUSBDevice.

We clearly see that the device takes a bit longer to appear on device manager. What we are expecting is an inspection and possible improvement on the timing in which the event is raised.

Hi,

You can find cyusb3.sys driver version 1.2.3.20 after installing Fx3 Sdk from below link:

https://www.cypress.com/documentation/software-and-drivers/ez-usb-fx3-software-development-kit

Please find the driver in the below path after installation:

C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\driver\bin\Win10

I tried that version, the issue remains.

The updates that seem to me messing with the timings are the latest months.

Miguel

Hi Miguel,

Can you please let me know the windows version you are using. You can use 'winver' in Windows+R to get it.
