Hi Michael, and thanks for your very detailed bugreport, it's greatly
appreciated.
Without much insight into your specific problem, would the (quite invasive)
attached patch solve your problem ? It's the backport of latest upstream
CUPS libusb backend over 1.5.3-2.3 .
Le samedi, 20 octobre 2012 01.03:40, Michael Biebl a écrit :
On a different note: I don't quite understand, by you modprobe the usblp
module on upgrades, but not in the init script
If the module is needed, shouldn't you also load it when you reboot?
If it's not needed, why the modprobe?
Well... As far as I understand it (and I'm a young cups bird), the module
should either be loaded by default or on-demand. It has been blacklisted for a
while so the postinst ensures that a non-rebooted system upgraded through
these versions would get a loaded module. I think (but might be wrong), that
the module would otherwise be loaded.
Looking forward for the results of the attached patch!
Cheers,
OdyX
