Not sure why, but the drx-k doesn't let the firmware to be reloaded at resume. Once the firmware is loaded, any trial to reload it makes the device to misfunction. Also, re-sending the init sequence that it is there at em28xx also makes it unstable. I suspect that a certain specific shutdown sequence would be needed for it to work, but I was unable to reproduce it. Perhaps the issue is related to either some I2C gateway at the analog demod (we don't have a driver for it) or some GPIO sequence is needed to reset it. So, I'm giving up for it for today. I may give a second trial if I won't be side-tracked by some other issue.
