[PATCH 5/5] TTUSB DVB driver update
From: Michael Hunold
Date: Sun Jan 18 2004 - 13:46:31 EST
- [DVB] TTUSB-DEC update by Alex Woods:
- fix USB timeout bug under 2.6
- change some variable names to make it clearer what we are dealing with (PVA).
- support DEC2540-t and add info on it to the ttusb-dec docs.
- add model number returned from DEC2540-t firmware.
- add a module option to get the raw AVPES packets from the dvr device.
- send audio packets to their filter rather than the videos.
- handle the new empty packets that appear with the 2.16 firmware.
- extra error checks.
- handle the new firmwares that change the devices' USB IDs.
- tidy up the STB initialisation process a little.
- apply Hans-Frieder Vogt's patch for calculating firmware CRCs.
- [DVB] make TTUSB budget card depend on USB subsystem
