#195 Problem with usb/parallel port adapter

[Anonymous]

I have no parallel port on my computer thus I bought a usb/parallel port adapter to be able to use my propic II programmer.

The adapter is well recognized, /dev/usblp0 is well created, but I cannot open it with pikdev (it saids Connexion : erreur).
With strace I found the problem : the port is correctly open but some ioctl fails :

open("/dev/usblp0", O_RDWR) = 9
ioctl(9, PPCLAIM, 0xb210738) = -1 ENOTTY (Inappropriate ioctl for device)
ioctl(9, PPRELEASE, 0xbfc06ee8) = -1 ENOTTY (Inappropriate ioctl for device)

It is not possible to use piklab on a usb/parallel adapter ?

Normall usb/parallel adapter is only for printer which does not emulate a real parallel port. This will not work under any OS, including Windows and Linux.
