[USRP-users] unrecognized WBX daughterboard in B100 under Windows 7

Hi, all,

I am trying to use USRP B100 and WBX under Windows 7. Received signal is
always zero with any carrier freq, sample rate, gain etc. uhd_usrp_probe
can not correctly recognize the daughterboard, full output is listed below.
It always happens at fast machine under 64-bit Windows 7 and it happens
in most cases at slow machine under 32-bit Windows 7. Very rarely at
slow 32-bit machine, uhd_usrp_probe correctly detect WBX frontend, but
received signal is still zero.
UHD and GNU Radio are installed according to wiki guide, latest stable
release. USRP B100 and WBX are just from the box.

C:\Users\iliya>uhd_usrp_probe
Win32; Microsoft Visual C++ version 10.0; Boost_104700;
UHD_003.005.001-release

-- USRP-B100 clock control: 10
--   r_counter: 2
--   a_counter: 0
--   b_counter: 20
--   prescaler: 8
--   vco_divider: 5
--   chan_divider: 5
--   vco_rate: 1600.000000MHz
--   chan_rate: 320.000000MHz
--   out_rate: 64.000000MHz

UHD Error:
     The daughterboard manager encountered a recoverable error in init.
     Loading the "unknown" daughterboard implementations to continue.
     The daughterboard cannot operate until this error is resolved.
