Hi,
I installed libusb-win32-filter-bin-0.1.12.0.exe to c:\LibUSB-Win32.
I compiled the sys and dll (cd /cygdrive/c/LibUSB-Win32/src; make all).
I installed the USRP windows driver following the description at
http://gnuradio.org/trac/wiki/USRPWindowsDriverInstall
When i look at the driver property in the device manager
i see that 'the device is working properly'. The libusb test program
detects the device as well.
When i run ./test_usrp_standard_rx.exe i get:
usb_control_msg failed: usb_control_msg: sending control message failed,
win error: A device attached to the system is not functioning.
rx_overun
xfered 1.34e+08 bytes in 4.25 seconds. 3.158e+07 bytes/sec. cpu time =
0.297
noverungs = 1
I get the first error message with any tool i try to access the USRP
(usrp_rx_cfile.py for example).
usrp_oscope.py displays the same error message but i see the signal
graph (but almost no amplitude).
