Have you looked at all at the Siren board? It's part of the HPSDR and
Suitsat II projects: a low-power, low-cost SDR engine using the dsPIC33F
embedded controller from Microchip. The current design uses 10 MHz RF in and
out, and the QSD and QSE for complex sampling and excitation. There i

Hallo,
at least how I decipher usrp-hw/usrp/interface.pdf, the USRP doesn't monitor
VBUS. As the Cypress application note AN15813 states, this may be an endless
source of problems when booting the PC host, hotplugging the USB cables etc.
