Hi,

I've fixed the remote control key codes as they have been in the original
Cinergy T2 driver with the attached patch. I set the OK to work as enter
and blue to be ESC for test purposes.

This is only a debug message. I'd be interested to know from what button
they were generated from. In the long run I'll just disable this message.

It doesn't work because the driver has lost the connection to the USB-device.
Please be sure to try the attached latest version of the driver because
not all
of the oldest one's support sleep modes!

The problem with removing and reattaching the CinergyT2 usb-device from
the computer without unloading the driver first is a bug of the dvb
framework and of Cinergy's new driver. To my understanding it happens
because the framework calls  symbol_put_addr(ptr) for a drivers
fe->ops.release pointer twice. First because the usb system reports the
device as removed and the second time when the frontend-release callback
is being called. This is for sure messes up the module usage counter as
well (ie. you won't be able to unload the Cinergy driver without a
reboot).

Please try this hack (it's easy to fix it by hand):
