Please share the screen shot of the device manager and also check the VID PID of the device. What is happening if you reset the device without providing power cycle?
Thanks & Regards
Please refer Question 1. in this KBA - The custom board designed using FX3 is not enumerated as “Cypress FX3 Bootloader Device”. Why?
Note that this KBA applies to FX3/CX3/FX3S.
Can you please load any example firmware to RAM and check the enumeration?
Also try to check with another Windows Machine - different OS/ different model Laptop
You can even connect to USB 2.0 port and test. Note that the USB bootloader works only in USB 2.0 mode.
