Hi,
I am using ISP 1561 PCI - USB controller in my project (with MVL
3.1). I am able to configure the root hub with ehci-hcd.o. But it is
not enumerating when a device is attached (tried with mouse). When
no devices are connected, the /proc/usb/devices lists the root hub's
configuration. After a device is connected, it does not display
anything more than what it used to display (still just the root hub
configuration) . I have attached the kernel messages with this mail
for the reference. I have also attached the contents of
/proc/usb/devices (log2.txt) and lsmod results (log1.txt) We have
added some printks inside the usb_control_msg function for debugging
purpose.
Thanks,
Jayaprakash.
