Cache important USB string descriptors all at once.
On platforms without udev support we must open a libusb device handle
in order to read string descriptors from the device. Rapidly opening
and closing the handle could cause problems with the platform's USB
stack so this patch caches the manufacturer, product and serial number
strings all at once. It also prevents a leak of the device handle by
explicitly closing it.
