That's what I thought. To answer the question: repeatedly calling
uhd_find_devices gives the same result. Even calling it after
successfully running my GRC test script doesn't change anything. For
the record, all I'm setting in the GRC test script is the IP address
to talk to (addr=192.168.10.2), the center frequency, and changing the
sample rate to something more appropriate for the USRP2 (2Msps right
now), and gain is left at 0 dB.

Hmmm - to try something else: if I call uhd_find_devices with the IP
address, it works

$ uhd_find_devices --args addr=192.168.10.2
--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
name: USRP2
addr: 192.168.10.2


Current rx socket buffer size: 131071
Using: Flex 2400 Rx MIMO B (0x0027)
Using: Flex 2400 Tx MIMO B (0x002b)

Not sure why it's behaving differently though. Calling just plain
uhd_find_devices again afterwards still gives 'No UHD Devices Found'.
