When printing a page on a USB printer, the job often stops somewhere in the job (e.g. after half a page). When using the same printer with a parallell port, the jobs goes through. Communication problems?
This defect is considered MUST-FIX for Winston Release-Candidate #1
Does it stop altogether? With the USB in 2.4.0-testxx I was seeing occasional long delays with USB, which seemed to go away with test5. Perhaps there are some backported fixes we need?
Yes, it stops altogether. Please check for important fixes in test5 (there are some wrt. USB storage as well, which I would like backported... possibly more)
Is this with ohci, uhci or usb-uhci by the way? I don't know the USB code very well so I'm not sure which changes we want..
uhci Printing works fine with a USB-to-parallell-port converter, BTW - but not with the native USB driver.
Does 2.2.16-18 make things any better?
yes, it works fine now.
