Cache vendor, product and serial info for each usb device. This allows
ioctl(USB_DEVICEINFO) not to issue any further requests to gather
information. Thus reducing stress on connected usb devices.
This fixes an issue where usbdevs called in a loop causes a USB mass
storage device to halt operation.
Adapted from a similar commit in NetBSD.
