Hi, If you've got problems getting the new USB stack working on non-x86 processors, try to disable all compiler optimizations when you compile the USB module. I am sorry to say that there is a bug in GCC that prevents some parts of the USB code from functioning correctly. And don't ask how many hours were wasted debugging this. And yes, the code is plain simple C. I've gotten some help debugging this, but if more people want to help, send me a private e-mail, and I will give you the details on the exact problem so far. Is this an indication that we might have to remove -O2 from the kernel compilation flag? --HPS
