common DVB USB issues we has currently
Hello,
Here we are, that's the first part I am going to fix as a GSoC project. Work is planned to start after two weeks but better to discuss beforehand.
And wish-list is now open!
I see two big DVB USB issues including multiple small issues;
1)
Current static structure is too limited as devices are more dynamics nowadays. Driver should be able to probe/read from eeprom device configuration.
Fixing all of those means rather much work - I think new version of DVB USB is needed.

2)
Suspend/resume is not supported and crashes Kernel. I have no idea what is wrong here and what is needed. But as it has been long term known problem I suspect it is not trivial.

What does this link above have to do with problem #1? Did you perhaps cut/paste the wrong link?

I doubt this is a dvb-usb problem, but rather something specific to the realtek parts (suspend/resume does work with other devices that rely on dvb-usb).

Dunno if it's at all relevant but I used to be able (circa 2.6.32 perhaps? it's a bit foggy now) to suspend/resume with my HVR-950q installed and modules loaded. Now suspending with them loaded hangs the suspend and they can't even reliably be rmmod/modprobed pre and post suspend/resume.
I just wonder if that change in behavior is pointing at something.
Cheers,

That means HVR-950q is not "DVB-USB" device OR it does not have DVB-USB-firmware to load by the DVB-USB-driver.

I have the resume problem with the terratec H7.

It crashes Kernel for every DVB USB device having DVB USB firmware.
