The problem is as follows: if my device is connected via USB to the disconnected from mains PC, it hangs. With USB disconnected, or p...

I don't know how clean is this workaround, but at least it works for me. I just run this every 10s: USB_INTR_ENABLE &= ~(1 << USB_INTR_ENABLE_BIT); usbDeviceDisconnect(); _delay_ms(500); // or some other sort of delay usbDeviceConnect(); USB_INTR_ENABLE |= (1 << USB_INTR_ENABLE_BIT);

You can reconnect automatically if you connect the D- pull up resistor to an I/O pin instead of Vcc. Do we really need extra IO pin to enforce re-enumeration like we do it just after usb initialization? Like this: usbDeviceDisconnect(); _delay_ms(500); usbDeviceConnect(); Unfortunately I have no sp...

If after some event PC loses USB-connection with device (with v-usb driver, of course) while physically it is still there, the connection can only be restored by either resetting the device or by unplugging it and then connecting to PC again. Somewhat similar problem is described in this thre...
