Subject: common: Add USB_DeviceSetVendorId() and USB_DeviceSetProductId().
X-Git-Url: http://git.code-monkey.de/?p=gps-watch.git;a=commitdiff_plain;h=d6527916c38428842248f558fa6716d8d6ba4871

common: Add USB_DeviceSetVendorId() and USB_DeviceSetProductId().

These configure the VID/PID pair to use.
