Hi,all Merry Christmas! Everybody. This issue has puzzled me some time. Can you guys give me a guide. There is an issue using the AMD CS5536 and an MIPS CPU. When transferring files via USB HD , the USB mouse will hang sometimes and lose connection to OHCI Host and this device can not be connected again from then on. I am debugging on this and add some printk() function in ohci_irq() to see OHCI host registers. Very surprising, the USB mouse connection lost issue can not be found. I don't know why. From the debug info, I see the ohci_irq() will be triggered always when I insert the USB HD at the same time, so can you tell me some hints about this? How can I debug that?
