Hi,
Does anyone know why some USB mass storage devices work and some don't on the same board with the same u-boot 1.1.3? I was able to track the msg down to hc_interrupt() used by submit_common_msg() in ./cpu/mpc5xxx/usb_ohci.c file. The hc_interrupt() always return 0xff (SF) and the submit_common_msg() in its for-loop times out on SF eventually.
Regards,
Winston
