[PATCHv2 1/2] usb: hub: Per-port setting to use old enumeration scheme

The "old" enumeration scheme is considerably faster (it takes ~244ms instead of ~356ms to get the descriptor). It is currently only possible to use the old scheme globally (/sys/module/usbcore/parameters/old_scheme_first), which is not desirable as the new scheme was introduced to increase

[PATCH] usb: hub: Per-port setting to reduce TRSTRCY to 10 ms
