USB audio device stops playing audio Hi all, I have an external amplifier for my speakers/headphones ( a NAD D3020 ) and after upgrading my Win 7 system to Win 10 recently, I have started seeing an issue where after a certain amount of time, the audio from the amplifier simply stops working over USB.
USB interfacing with PIC microcontroller with code
https://microcontrollerslab.com/usb-interfacing-pic-microcontroller-code/
CLOCK GENERATION for USB interfacing with pic microcontroller P18F2550/4550 supports low speed (1.5 Mb/s) and Full Speed (12 Mb/s) so for USB we have to select a specific clock. An internal clock of either 6 MHz or 48 MHz is required because of timing requirement imposed by USB.But there is a problem in using the crystal of 48MHz.
