Hi everybody,
I am working with the JM32 microcontroller and trying to detect
the USB connectivity between the micro and the host PC.
Can i check the connectivity in the USB_ISR() : Interrupt 7.
This will help me reset the host PC when there is no USB communication.
USB cable is attached correctly, but the source of trouble in USB communication
is the driver in the host PC side that needs a reboot of the host PC.
Regards
Sound like the PC class driver hangs, rather than a problem of USB connection.
1) What is the OS, Windows?
2) What is the USB class?
> but the source of trouble in USB communication is the driver in the host PC side that needs a reboot of the host PC.
Soft-detach / attach on the device will work to release the PC class driver from hang.
