Well I got the solution Its some python version problem. With 2.7.2 its working fine. I have 2.6 in the problematic systems. So told by Josh I removed the " errors=‘ignore’ " from usrp2\_card\_burner.py from line 53 and it worked finally. 😃 sumitstop wrote: > > > ``` > > > self._raw_dev_entry = DeviceEntryWidget(self, text=dev) > > > > > > ``` > > > > > > TypeError: decode() takes no keyword arguments * * * ## Sumit Kr.

Its a UHD bug that was introduced from a language fix for the card burner. So I can fix it, please tell me: What version of python are you running? Does the app work if you remove “errors=‘ignore’”? -josh
