OK, I rebuilt Angstrom with libusb-0.12 ans tested on my Gumstix Overo. The Overo has a working EHCI host port. (Well after I removed a speck from the back of the board called R26) Enough about my problems and eyesight.

Running :

# ./test_usrp_standard_rx -D 10
xfered 1.34e+08 bytes in 5.27 seconds. 2.547e+07 bytes/sec. cpu time = 3.969

# ./test_usrp_standard_rx -D 256
xfered 1.34e+08 bytes in 134 seconds.  1e+06 bytes/sec.  cpu time = 0.2422
noverruns = 0

# ./test_usrp_standard_tx -I 512
xfered 1.34e+08 bytes in 134 seconds.  1e+06 bytes/sec.  cpu time = 5.14
0 underruns

# ./test_usrp_standard_tx -I 24
xfered 1.34e+08 bytes in 6.29 seconds. 2.133e+07 bytes/sec. cpu time = 5.38
0 underruns

10 is the smallest decimation without overruns and 24 is the smallest interpolation without underruns. I doubt we can do much at the higher rates, but the basic numbers look good.
