Hi,
While burning CD's on 2.6.9 with cdrdao, I noticed it complaining repeatedly: ERROR: Read buffer capacity failed.
It tries to read the buffer capacity (MMC command 0x5c) in order to produce a percentage reading of how full the buffer is.
This patch permits the READ_BUFFER_CAPACITY command again. Please apply.
