Hi, I've been trying to merge an already existing driver for Terratec Cinergy T2 digi-tv into newer DVB-USB "framework" (ie. get the cinergy driver to be compliant with the rest of the usb digi-tuners).
However, I seem to have a problem with this modified driver as the device gets disconnected from the usb-bus sooner or later (after 10-48h of operation). Until the disconnection the driver & device seem to be working just fine. In order to figure out what is the actual problem in communication I retrieved the following usbmon debug log, but I have problems in understanding it. Anybody care to help a little bit ?
