This patch improves the strategy uhci-hcd uses for performing controller resets and checking whether they are needed. The HCRESET command doesn't affect the Suspend, Resume, or Reset bits in the port status & control registers, so the driver must clear them by itself. This means the code to figure out how many ports there are has to be moved to an earlier spot in the driver. The R/WC bits in the USBLEGSUP register can be set by the hardware even in the absence of BIOS meddling with legacy support features. Hence it's not a good idea to check them while trying to determine whether the BIOS has altered the controller's state.
