I have two questions about this hunk:
- is this a safe code path?
....
/* Remove it from uhci->urb_list */
list_del_init(&urb->urb_list);
out_complete:
uhci_add_complete(urb);
out:
spin_unlock_irqrestore(&urb->lock, flags);
}
The last two lines appear in this patch.
- I get errors when I make this a #if 0:
if (urb->status != -EINPROGRESS) {
info("uhci_transfer_result: called for URB %p not in flight?", urb);
#if 1
spin_unlock_irqrestore(&urb->lock, flags);
return;
#endif
goto out;
}
pre6 gives me this dmesg output and a halfworking bluetooth
kbd/trackpad. (trackpad does not work, some garbage in /dev/input/mice)

with pre7 I get stall/crc errors:
Same happens with the usb-uhci-2-2.4.19-pre6-patch applied, I tracked it
down to the hunk mentioned above.

It is a Siemens Celsius mobile H notebook, is the usb controller really
supported? The bluetooth kbd/trackpad is on hub3 and it does only work
with uhci, usb-uhci gives me error -84. I wonder if something is really
wrong because the trackpad does not work. This is the hexdump output
from an external usb mouse, pressing the mouse button:
siemens:~ # hexdump /dev/input/mice
0000000 0009 0800 0000 0009 0800 0000 0009 0800

0000040 0000 0009 0800 0000 0009 0800 0000 0009
And this from the trackpad:
siemens:~ # hexdump /dev/input/mice
0000000 0008 0809 0800 0008 0809 0800 0008 0809

As you can see, it has some more bits set...
