I'm using STM32F103 in a battery powered device with USB (external power and data transfer over virtual com)
When i run my device without power down and connect USB to PC everything ok.
But after power down and wake up (RTC) my device isn't recognized from PC.

I'm using FirmLib V2.2.0 (i know bit old).
I enable USB clock, init NVIC and USB_Init(),....
nothing works - also i tried is SetCNTR to reset USB - no chance...

i've searched the forum and half internet - no hit
Knew anybody an example for my task - or perhaps an idea?

would be great if one hat a little bit time to answer

thanx otmar
