If you check usbd you will see that the first thing it does is to enumerate the tree and that stalls at not getting interrupts after sending the requests to the hub. The timeout is 5 seconds I think and it does several requests, so 30 seconds to a minute sounds plausible. You need to dig around in the interrupt routing.
