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. | |
