Problem with usb in my embeded system
running on linux2.6.23. After I compiled the kernel and tried to do the
>> insmod ehci-hcd.ko
I got the following message:
ehci_hcd 0000:01:0d.0: EHCI Host Controller
ehci_hcd 0000:01:0d.0: new USB bus registered, assigned bus number 1
ehci_hcd 0000:01:0d.0: can't setup

ehci_hcd: probe of 0000:01:0d.1 failed with error -110
I also inserted the following modules
And they gave no errors.
However, no matter what usb devices I plugged in (usb camera, storage etc),
the board just gave no response (through the command dmesg).
Does anybody know what is wrong? Also does anybody know how to find out the meaning of error code -110?
Thanks in advance.
