USB resume not waking device from Standby

[hbucknell]

Has anyone experienced this problem? We want to place the device into a low power mode while the PC is Sleeping, but when the PC powers up the device does not wake correctly.

Confirmed. Same here. To solve the issue i run watchdog interrupts, they wake device, i service them, and if usb is not awake i'm entering to low power mode. 300mS of high power, every 3 seconds is best it can do. It seems that usb interrupts cannot wake device. Unless we both are doing something wrong.
