Hi,
is this really needed ?
case USBDEVFS_DISCONNECT:
driver = ifp->driver;
if (driver) {
down (&driver->serialize);
dbg ("disconnect '%s' from dev %d interface %d",
driver->name, ps
Hi,
is this just me or this call disconnect() on an already disconnected device ?
IMHO we need to recheck after taking the semaphore. Comments?

Hmm, what about the interval? What's the endpoint's bInterval? Try
setting the URB's interval to that. I think you have to use an
interrupt URB to use the interval.
If you could get to a bus tracer, it'd make it much easier ;)

In Linux 2.4.18 with usb-uhci (v1.275), the following code will create
a TD with wrong toggle bit:
urb->pipe = rcvbulkpipe( ... );
urb->dev = dev;
usb_submit_urb(urb);
/* optionally: receive some data and resubmit the urb */
usb_unlink_urb(urb);

Hello,
I have developed a driver for an ADSL USB adapter, which is using Interrupt
OUT pipes. With the uhci and usb-uhci drivers this works fine, but with ohci
I am not able to kill the urb. With the uhci driver, in order to submit the
urb only once, you set the urb->interval to 0. This is not te

what's the format of the URB you send? The size should be exactly the
ep's bMaxPacketSize...

Hello,
I'd like to send a signal out from a kernel module to a user application.
But the declaration of fasync_helper is misunderstanding. So I get kernel

I use Kernel 2.4.18. Rubini's example says:

thank you, indeed I needed this confirmation.
