Is there a free tool that can take USB logs from windows and replay them at a
slower rate on linux so that you can find out which commands to a device do
what? Thanks,

I'm maintaining a driver which uses usbvideo.h. The problem I'm having with
distributing it is that if users don't have the kernel source installed,
there is no copy of usbvideo.h on their system, so I'm having to distribute a
copy of it with the dr

Is there anywhere where I could find a guide to decoding the usb sniffs from
USB Sniff or Snoopy Pro? This is the basic format of the logs I have:
[11610 ms] >>> URB 15 going down >>>

TransferFlags = 000

Well it doesn't really matter to my device as far as I know, so I might just
do that instead. *looks up docs* Thanks,

Okay here's another round of useless stupid questions:
When I register a driver with usbvideo, what happens? I've got printk's in my
probe function and it never seems to get called. What do

I'm writing my device driver for a webcam here, using usbvideo.h. I'm using
ibmcam.c as an example of how to build a usb video driver.
This is my id_table:
static struct usb_device_id id_table[] = {
{ USB_DEVICE_VER(VOLCANO_DG640E_VENDOR_ID

Is there a way to get direct access to a device on usb via usermode? I'm just
thinking it might be easier to try and figure out how to use my device from
that mode. Thanks,

Is there some documentation for using usbvideo to create a usb camera driver?
I'm sorta copying another driver, but it would be nice if I understood what
some of this stuff means.
For instance, what is usbvideo_cb_t? Thanks,
