1- I'm using the host USB not the OTG 2- I'm using the 2.6.37 kernel with Angstrom 2010 3- The following is the dmesg output which looks ok ... at least to me :)

I am able to use it to receive IQ data from the USRP but I can't seem to transmit anything from it ... if I take the same flowgraph to a laptop I'm able to transmit IQ using the same USRP/daughterboard and the UHD driver however when I try to run the same transmitter on the Beagleboard and I check my spectrum analyzer I don't see anything > > I already did a signal capture before sending to the USRP and made sure that there is data getting pushed through ... is there a problem with UHD/USRP sinking on the E100 and the Beagleboard ???

What kernel version? Can you run dmesg and see if there are any usb related messages at the end? Philip
