Yes Alan, I can see the messages as 1. usb 1:1 <Controller 1> 2. usb 2:1 <Controller 2> But in the ioctl, I wrote to test for my sake. In the code it is taking Controller 1 only as i can print roothub devnum, which is always one. I am manipualting but getting kernel crash. Can u please guide me to make changes so that my code will handle the two host controllers properly. many thanks, Prabhu On Wed, Jun 24, 2009 at 8:32 PM, Alan Stern<stern@xxxxxxxxxxxxxxxxxxx> wrote: > On Wed, 24 Jun 2009, Prabhu Chawandi wrote: > >> Hi All, >> >> I am my device, there are two host controllers with one prot each. >> >> I want to check which contoller is being used for, So may I know where >> is the piece of code which cam help me to check >> >> cotroller under use ... > > It's easy to find out which controller is connected to which port. > All you have to do is plug a USB device into one of the ports, and then > look at the messages appearing in the system log.
