thanks for your great efforts to get external devices with genesys chipset working with ehci!
Since Kernel 2.6.4 the device hangs when burning CDs with cdrecord or cdrdao during sending the cue-sheet. The only case where this does not happen is when using tao mode for data CDs.
Might this be a side-effect of the new routines checking for the "00 00 00 ..." packets that the genesys chip produces? When using verbose mode in cdrdao the cue-sheet is printed to the console, and it contains a lot of "00 00 00 ...".
Sorry for this unprofessional description, maybe someone can check this with her/his device or give me instructions what debugging information would be needed to resolve this. See output of "cdrdao scanbus" and "lsusb -v" below.
Please CC replys to my PM, because I am not subscribed to the list.
Thank you! Andreas.
