I couldn’t find the operating temperature for the Black Wireless specifically, does anyone know what is the operating temperature?
What I was able to find with a quick search on the BBBW System Reference Manual Wiki.
During normal operation, some circuit components may have case temperatures greater than 60 C as long as the input and output are maintained at a normal ambient operating temperature.
The other notable info I found was:
USB Ports 2 Operating Temperature Range © -40 to 90
Not sure if what I provided is of any help. My guess from what I can find is that the temperature ranges are probably dependent on what the components themselves can handle.
Did you ever get an official reply on this?
