Error when power on Radio Receiver

[loloderu]

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):

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.
