there is very few topic for this on the internet and some customer ask me this so i decide to write it down.
the only useful information i can find for running HDSDR with usrp b210 is http://spench.net/r/USRP_Interfaces
but it is still complicated and all it do is generate the usrp related files for HDSDR. so here i compact the files in HDSDR usrp file.rar (4 MB)
download HDSDR from http://hdsdr.de/index.html
install HDSDR then uncompact the usrp related files and copy them to HDSDR install path which normally is C:\Program Files (x86)\HDSDR
then run HDSDR with usrp connected, when the HDSDR window show up it will detect usrp then download firmware.
