Hi Marek,
Here I thought I good get away from always spending my time working on USB
by hobbying a bit with ARM devices, only to end up doing USB work :)
I'm happy to report though that I've gotten USB keyboards to work reliable
with u-boot on Allwinner/sunxi devices. This is a first set of
ENODEV menas no usb keyboard was registered, threat this as a successful
usb_kbd_deregister.

Hi Marek,
Here is the second set of USB patches / fixes I've been working on, currently
u-boot does really bad things (tm) when doing usb reset while using an
usb keyboard. This set fixes this.
Given that these fix really bad things (tm) I not only believe that these are
suitable to go into
We need to call usb_kbd_deregister() before calling usb_stop().
usbkbd's stdio_dev-priv points to the usb_device, and usb_kbd_testc
dereferences usb_device-privptr.
usb_stop zeros usb_device, leaving usb_device-privptr NULL, causing
bad things (tm) to happen once control returns to the main loop
We now always properly deregister the keyboard before calling
drv_usb_kbd_init(), so we can drop the check for already being registered.

Use the new force parameter to make the stdio_deregister succeed, replacing

the reset.

In some cases we really want to move forward with a deregister, add a force

Hi Marek,
This time a patch-set for next :)
Currently one can choose between 2 poll methods for usb keyboards, both of
which are suboptimal. One option is to use control messages to get reports,
which some devices (e.g. my kvm) do not like. The other option is to use
interrupt urbs, but

Hi Marek,
And last 2 misc. fixes for USB for next. The first patch is self explanatory,
the second patch is a result of me looking into why u-boot's usb scanning
is so slww, not that it really helps there, but it is a tiny start.
I've several other ideas how to speed things up, but those
Do as the Linux kernel does and power on any ports which are not yet one,

If the device has a parent, it is instantiated from usb_hub_port_connect_change
and the portnr is right there in dev-portnr, so there is no need for this
