50 * Known Issues :
51 * LME2510: Non Intel USB chipsets fail to maintain High Speed on
52 * Boot or Hot Plug.
53 *
54 * DiSEqC functions are not fully supported in this driver. The main
55 * reason is the frontend is cut off during streaming. Allowing frontend
56 * access will stall the driver. Applications that attempt to this, the
57 * commands are ignored.
58 *
59 * PID functions have been removed from this driver version due to
60 * problems with different firmware and application versions.
