Problem about CyU3PUsbSetLinkPowerState
When Fx3 works in U1 state,I use CyU3PUsbSetLinkPowerState(parameter:CyU3PUsbLPM_U0) for the transition "U1->U0",and then check the state through "CyU3PUsbGetLinkPowerState". but sometimes I found the result of "CyU3PUsbGetLinkPowerState" is CyU3PUsbLPM_U1, that is Fx3 exit back to U1, not working in U0 state. why?Is it a bug?
