[pvrusb2] WinTV PVR USB2 with Beagleboard driver

Tue Dec 15 09:58:32 CST 2009

   Dear Mike,

   Thanks for the reply.  Sorry to disturb you again.  I was wondering if
   you can make a quick comment on my progress.  I think I sucessfully
   compiled the pvrusb driver.  When I plug in your device I see the
   following errors:

   [ 2288.158325] usb 1-2.2: new high speed USB device using ehci-omap and
   address 6
   [ 2288.307006] usb 1-2.2: configuration #1 chosen from 1 choice
   [ 2288.502258] tveeprom: disagrees about version of symbol
   struct_module
   [ 2288.509490] v4l1_compat: disagrees about version of symbol
   struct_module
   [ 2288.518280] videodev: disagrees about version of symbol
   struct_module
   [ 2288.525970] v4l2_common: disagrees about version of symbol
   struct_module
   [ 2288.533966] cx2341x: disagrees about version of symbol struct_module
   [ 2288.542022] dvb_core: disagrees about version of symbol
   struct_module
   [ 2288.570526] pvrusb2: version magic '2.6.32 mod_unload ARMv7 ' should
   be '2.6.29-omap1 preempt mod_unload modversions A
   RMv7 '

   So it appears the pvrusb2 driver is fine now.  I don't know if the rest
   matter.  I still don't have /dev/video0 so the issue is either the
   above dependencies or you mention in your usage.html file about running
   udev.  I believe I have udev installed.  Do you think the /dev/video0
   isn't being created because of dependency issues or something else?

   Thanks for helping out.

   Marco

   Macro:
   The errors you are seeing are most likely because the modules weren't
   compiled against the kernel you are running. Either that or there are
   other modules that you need to install as well. With Linux it's
   critically important that you use modules matched to the kernel you are
   running.
   Are you sure you grabbed the right set of modules?
   Not being familiar with the beagleboard I don't know how software is
   being distributed for it. But if you have the ability to install a
   kernel source tree and compile your own modules against that, then you
   should certainly be able to simply compile the driver yourself.
   The FAQ entry you referred to is a good guess, but this problem is more
   basic - you're having problems with more than just that one symbol. The
   underlying issue here has to be due to simply using the wrong modules
   with the kernel you are running.
