Hi Josh,
I can't find width, height and so on in the .grc file.

Hi,
I'm having some trouble getting my N210 running using GRC. The problem seems to
be with the block 'UHD: USRP Source', as I get the following error when
building a simple project (USRP and FFT sink block):

Isn't LibUSB-Win32 the old libusb 0.1 driver? What happens if you uninstall
the driver in the device manager and reinstall with the libusb 1.0 driver?

hi all:
I want to use the gr-howto-write-a-block-3.3.0 (my version of the Gnuradio
