Hi, When I power on radio receiver I got 2 popup window error message showing: There was a problem: USB write failed (length 0x64000), rc=1, lastErrorMessege="Transfer failed". When I launch rtl_fm I can listen to the radio and see the folowing message Found 1 device(s): 0: Realtek, RTL2838UHIDIR, SN: 00000001

Using device 0: Generic RTL2832U OEM Detached kernel driver Found Rafael Micro R820T tuner Tuner gain set to automatic. Tuned to 89855000 Hz. oversampling input by: 6x. Oversampling output by: 1x. Buffer size: 8.03ms Exact sample rate is: 1020000.026345 Hz Create UDP thread Created UDP thread Main socket started! :-) Tuning enabled on UDP/6020 Sampling at 1020000 S/s. Output at 170000 Hz.

Do you have any idea of where this pb could come from?

Thanks for your help

I may be having a similar issue here, except all I get when I press [Power On] is nothing, and the close button doesn't function.

Host: Dell Chromebook 11 Device: NESDR SMArtee (0bda:2838) shows up as RTL2838UHIDIR SN 00000001 on Ubuntu. Does this chrome app directly write to 0bda:2832, and ignore 2838? Because the behaviour is the exact same when there's no SDR plugged in.

Edit: I discovered something in the dev console. Unchecked runtime.lastError: Permission to access device was denied Nothing closely related appears in the chromeos syslog (chrome://system) though.
