usb: Don't reset the USB hub a 2nd time Debugging has shown, that all USB hubs are being reset twice while USB scanning. This introduces additional delays and makes USB scanning even more slow. Testing has shown that this 2nd USB hub reset doesn't seem to be necessary. This patch now removes this 2nd USB hub reset. Resulting in faster USB scan time. Here the current numbers: Without this patch: => time usb start starting USB... USB0: USB EHCI 1.00 scanning bus 0 for devices... 9 USB Device(s) found time: 24.003 seconds With this patch: => time usb start starting USB... USB0: USB EHCI 1.00 scanning bus 0 for devices... 9 USB Device(s) found time: 20.392 seconds So ~3.6 seconds of USB scanning time reduction.
