Some USB devices break the spec and require longer warm-up times. Allow the usb_pgood_delay env variable to override the calculated time.
I have encountered this specficically with several different sized/branded USB sticks with VID:PID 058f:6387 (Alcor Micro Corp. Transcend JetFlash) where I need to set usb_pgood_delay to 2000ms to make them detectable.

Hi!
this looks like a good idea. I have a hint for improvement -- in case you get a timeout waiting for the device to be detected, maybe the error message should mention that you can try setting this env variable and try again ?
