I'm not a C programmer or kernel expert, but after boot devfs only knows, that there is a drive (without partitioning info). The problem is, that mount does not trigger a new lookup for the drive partitioning. > Are you using cooker kernel? If not what is the point of posting it > here? > > -andrej

Any such changes would not have been overwritten by the upgrade. Such changes, while allowing the drive to function in 8.1 would prevent the now properly functioning devfs from operating unless the same hack is used or unless all configs are returned to their default. As I said my USB Zip is functioning without problem and no changes were necessary. FWIW here is the fstab listings for my zip: /dev/sda /mnt/zip auto user,iocharset=iso8859-1,umask=0,sync,exec,codepage=850,noauto 0 0 /dev/sda4 /mnt/zip2 auto user,iocharset=iso8859-1,umask=0,sync,exec,codepage=850,noauto 0 0 Charles

And I can atest that I have to touch disc node first when disc is inserted, then part4 is generated. I.e. 'mount -t vfat /dev/host0.../part4 /mnt/zip' is otherwise not working. Or maybe it's a upgrade problem.

It must be working in current cooker kernel (old ide-floppy bug) and is being corrected in public driver in slightly different way (Chmouel, it probably will obsolete my patch). Are you using cooker kernel? If not what is the point of posting it here? -andrej
