So > FREQ5 clock source doesn't affect to USB host controller. After looking into it, both the comment and code are correct. From include/asm-mips/au1000.h: #define FQ_CNTRL_1 0xB1900020 #define FQ_CNTRL_2 0xB1900024 So FQ_CNTRL_1 corresponds to what is now sys_freqctrl0. In other words, the update to the databook has not been incorporated into the Au1000 files. The names of the registers were updated after I had done all the core work. I need to update the code so the names of the registers correspond to the latest Au1000 manual. Since the boards we have do work with USB and there were some usb hardware glitches, please check with Alchemy on what the problem might be with your board. Pete
