hi all,
I working on E100 with official image  UHD 003.004.
After booting,When executing uhd_find_devices and uhd_usrp_probe they fail
i think uhd_find_devices should have serial number.isn't it?
Any idea what is wrong.

root at usrp-e1xx:~# uhd_find_devices
linux; GNU C++ version 4.5.3 20110311 (prerelease); Boost_104500;
UHD_003.004.000-7dc76db
