hdpvr and HD PVR 2 Gaming Edition from Haoppauge

[Thomas Seilund]

Hi All,

I just bought the HD PVR 2 Gaming Edition from Hauppauge.

It there any change this device will be supported by the hdpvr kernel 
driver. (Or any other driver for that matter!)

When I insert the device only the usb module reacts. The hdpvr module is 
not loaded.

Then I updated the product id in the hdpvr module and now the hdpvr 
driver is loaded. but I get device init failed

I added this code:

- I patched hdpvr.h and added #define HD_PVR_PRODUCT_ID5      0xe502
- I patched hdpvr-core.c and added { USB_DEVICE(HD_PVR_VENDOR_ID, 
HD_PVR_PRODUCT_ID5) }

Now the driver sees the device but I get this in the dmesg when I attach 
the device:

[  201.311799] usb 2-1.2: new high-speed USB device number 5 using ehci_hcd
[  201.436217] hdpvr 2-1.2:1.0: unexpected answer of status request, len 
-32
[  201.436226] hdpvr 2-1.2:1.0: device init failed
[  201.436308] hdpvr: probe of 2-1.2:1.0 failed with error -12
[  201.436353] usbcore: registered new interface driver hdpvr

I looked closer at the driver code but this is way over my head!

I can make the device work on Windows.

Any help would be greatly appreciated.

Thanks

Thomas S

No.  It is a totally different hardware design and will need an
entirely new driver.

Do you know if anybody plans to make a driver?

I would love to contribute but my skills are not quite there!

I have looked at the code for hdpvr kernel driver and I will try to pick 
up more knowledge from the internet.

Do you have any hints on where to look?

Thanks

I have not heard of any such plans.  It's a brand new device though,
so it's possible that somebody will step up to do such (especially if
the original HD-PVR stops being sold).

The Linuxtv.org wiki has some docs on creating Linux USB drivers
(techniques for reverse engineering Windows drivers, collecting USB
bus traces, etc).  Normally I might suggest that you try to find the
datasheets for all the chips involved, but I can tell you that you
won't find them publicly available.
