| ) | [read] |
locate Nth (zero based) USRP device in system. Return pointer or 0 if not found.
The following kinds of devices are considered USRPs:
unconfigured USRP (no firwmare loaded) configured USRP (firmware loaded) unconfigured Cypress FX2 (only if fx2_ok_p is true)

| void usrp_one_time_init | ( | libusb_context ** | ctx = NULL | ) |
initialize libusb; Behavior differs depending on libusb version
libusb-0.12
Probe busses and devices. The argument is ignored and defaults to NULL. Safe to call more than once.
libusb-1.0
If an location to a libusb_context is passed in, create and write in the new context. If no argument is provided, initialize libusb with the default (NULL) context.
Generally _not_ safe to call more than once with non-NULL argument since a new context will be created each time.
