[DVB patch 43/48] dibusb: support dtt200u (Yakumo/Typhoon/Hama) USB2.0 device

From: Johannes Stezenbach
Date: Mon Mar 21 2005 - 20:58:31 EST

o added native support for the dtt200u (Yakumo/Typhoon/Hama) USB2.0 device
o URBs are now submitted, when the actual transfer began, not right from the
device plugin (solves a lot of problems)
o minor fixes in the dib3000-frontends
(Patrick Boettcher)
