One has to avoid U3 enhanced memory sticks here. On my

by the OS at plug time.)
This pseudo drive returns no write capabilities and a page
length of 28. MMC-3 describes page length 32. Regrettably
MMC-2 prescribes a page length of 26. Here i have to trust
m->cdrw_write to reliably indicate any MMC-2 burner.
