usbnet in loox720

Hi guys,

  i need your help...

I have rewritten methods for udc controlling (udc_detect, udc_command),
so they use valid GPIO and CPLD for pullup now.

The problem is.. i can't get it working on my computer :)
To be more, the same works for Jan Rinze.

I have no idea what to do with it.

Here is what I get in dmesg (on desktop):

First, when I reboot to wm2003, I get this:
usb 3-1.1: new full speed USB device using uhci_hcd and address 48
usb 3-1.1: configuration #1 chosen from 1 choice
ipaq 3-1.1:1.0: PocketPC PDA converter detected
usb 3-1.1: PocketPC PDA converter now attached to ttyUSB0

Looks good, but working USB under WM is not what I want ;)

Then I boot linux. When loading udc driver, it sends "disconnect"
command (and via CPLD disables USB PullUp):
usb 3-1.1: USB disconnect, address 48
ipaq ttyUSB0: PocketPC PDA converter now disconnected from ttyUSB0
ipaq 3-1.1:1.0: device disconnected

That's ok, you don't have to unplug USB cable from loox anymore.
But when udc does "connect", i get this:

usb 3-1.1: new full speed USB device using uhci_hcd and address 49
usb 3-1.1: device not accepting address 49, error -71
usb 3-1.1: new full speed USB device using uhci_hcd and address 50
usb 3-1.1: device not accepting address 50, error -71
usb 3-1.1: new full speed USB device using uhci_hcd and address 51
usb 3-1.1: device descriptor read/64, error -71
usb 3-1.1: device descriptor read/64, error -71
usb 3-1.1: new full speed USB device using uhci_hcd and address 52
usb 3-1.1: device descriptor read/64, error -71
usb 3-1.1: device descriptor read/64, error -71

... and that's all. Maybe you know this messages already and can help
me. I also invite you to test fresh kernel from my SVN repository and
tell me if it's working for you.

Thanks,
Piotr Czechowicz.
