Usually it’s a last TRB in TD. In case of ISOC transfer for bInterval > 1 each ISOC transfer contains more than one TD associated with usb request (one TD per ITP). In such case the TRB_SMM flag will be set in every TD and driver will recognize the end of transfer after processing the first TD with TRB_SMM. In result driver stops updating request->actual and returns incorrect actual length. To fix this issue driver additionally must check TRB_CHAIN which is not used for isochronous transfers.

Incase of cdrom, the fsg_lun_open call sets the sector size to 2048 bytes. When MAC OS sends a read_toc request with MSF set to '1', the store_cdrom_address assumes that the address being provided is the LUN size represented in 512 byte sized blocks instead of 2048. It tries to modify the address further to convert it to 2048 byte sized blocks and store it in MSF format. This results in data transfer failures as the cdrom address being provided in the read_toc response is incorrect.
