I tried Cy3684 EZ-USB Development Board installed hid_kb example which was form CY3684_EZ-USB_FX2LP_DVK (1.0),
And it worked fine on Windows System;
However, if I plug in it before PC turns on, while PC is booting process, the PC booting process is stuck.
I tested that PC entered BIOS then plugged in Cy3684 HID_KB USB, PC screen was frozen after then removed Cy3684 HID_KB USB, it recovered.
Does anyone know what happens? and How to salve the issue.
I tried to boot my Windows PC (Windows 7 Professional, Host Controller: C200 Series Chipset family USB Enhanced Host Controller)
I couldn't reproduce the issue. The booting process was not interrupted.
Could you check if this issue is specific to that PC?
