Hello, I am trying to hack together USB Host support for Motorola EZX series of linux based smartphones (like E680i, A780, A1200) and I am stuck with device enumeration. (details see http://www.seili.net/a780usb.php). These phones run a Montavista Linux 2.4.17 with usbfs disabled on Intel PXA271.
I can connect a device and the CCS (Current Connection Status) bit in the Ports Root Hub register is beeing set, so I think I got the physical things ok (resistors, multiplexing of GPIO function, etc...). However, nothing happens afterwards. No messages in dmesg. Steady signal (DC) on the oscilloscope. I am a USB newbie and a bit confused now. The docu I found was mainly related to how to write a new USB device driver. * How exactly did a Linux 2.4.17 learn that a new device was connected to a OHCI controller ? By Interrupt ? * And how does the virtual root hub know how many ports there are and where they are ? * Is there a way I can tell how many ports there are without usbfs ? * Or if a new device was connected again without usbfs ?
