changes in 10.211:
USBD:
1) increase power-on delay on hub attach
USBPRT:
1) attempt to fix the problem of non-connecting printers
(USB port driver shows the printer as not connected even though it is and USBD.SYS correctly reports it as attached)
USBUHCD,USBOHCD,USBEHCD:
1) protect all write to PCI config space registers by disabling interrupts
USBMSD:
1) add additional tracing
2) change the command sequence for device attach to what Windows does when new device is attached. That will hopefully increase the likeliness that a MSD device will attach successfully
3) add additional delays to commands issued on device attach, there are devices that need some delay in between commands
4) change geometry computation to match what DFSee expects, in particular, compute a (preferred) device geometry (base for formatting) and a possibly different current media geometry (read from the current media)
