FYI, I'm using a printer daisy-chained to a backpack CDROM drive and pass-through sort of works in 2.2.5-ac6. Sort of because I can access the CDROM or the printer, but not simultaneously. If I access the CDROM while printing, for example, the printer immediately stops.
I'm just relating this as anecdotal evidence that the pass-through code is not entirely broken. Heck, maybe even simultaneous access works and I'm only doing something wrong (e.g. the lp driver uses irq 7 while the paride/bpck/pcd modules appear to be polling in 4bit mode...)
I'm about to re-subscribe to the parport mailing list, but how many mailing lists can one subscribe to before losing total control of incoming e-mail?
Cheers Steffen.
