I have never used the chip with edge-triggered interrupts, while it is working in two different designs here as level triggered. If your processor supports level-triggered interrupts, you should perhaps try using them. I don't remember exactly, what you have done already to get irq stuff working. Ignore the following, if you have done this. Dump all the processor's interrupt/gpio registers related to the pin which must get interrupts from isp to make sure the pin is indeed correctly configured. Assert/deassert the interrupt pin manually to see, whether it really changes the relevant status bit in the raw interrupt register. Achtung!!! Doing this may require disconnecting the interrupt pin from ISP to avoid damage to the latter; consult with your hardware guys. Then modprobe the isp116x-hcd and see whether a manual assertion of the pin will increase the interrupt count in /proc/interrupts. Dump again the contents of interrupt/gpio registers to see, whether they are still in the right state. Then reconnect isp's interrupt pin if previously disconnected and redebug the isp settings. Sorry, this went far from USB. Olav ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
