Re: [PATCH] USB: add Sensoray 2255 v4l driver

Hi Oliver,

Just to be clear. You mean fixing the loading issues(ugly msleep, etc...) that Mauro mentioned, not the YUV formats(which seem unrelated)?

Would it be ok to have just 422P and greyscale in the driver for now if we can't get a firmware update in a reasonable timeframe? It's certainly not ideal, but we could direct our customers to the libraries, at least until we get a proper HW fix.

Best regards,

Hmmm... what happens if the user plugs two or more of such devices?

Concurrent calls to open() will be delayed. Not a problem, if the
firmware issue is fixed as it needs to be.
