usb: Assimilate usb_get_descriptor() to linux
Before this commit, usb_get_descriptor() failed for some flakey USB
devices. We hereby adopt the more robust linux implementation [1].
For instance, for the "Alcor Micro Corp. Flash Drive" (VID 0x058f, PID
0x6387), the following behavior occurs from time to time:
=> usb start
starting USB...
Bus xhci_pci: Register 10000840 NbrPorts 16
Starting the controller
USB XHCI 1.20
scanning bus xhci_pci for devices... usb_new_device: Cannot read configuration, skipping device 058f:6387
