Hi all, We are testing EHCI driver for ARC based controller core on a ARM 926 board. The platform glue has been written. The driver is compiled to the kernel . When the kernel boots up , the driver is loaded.
We have enabled USB_DEBUG and then going through the prints, its is observed that the root hub has been identified and given the address 1. But when we plug a High Speed device , the IRQ function is not even invoked, the STS register and PCD bit in PORTSCx is not showing any change. Those who have worked with ARC USB HS-OTG controllers, have u come across these problems, if yes, please help us. I am attaching the log of trace i did.
