[-- Attachment #1 --] I finally got fed up enough with not being able to print with -CURRENT, and found a fix that make ulpt work for me with my epson stylus photo 835. I am using cups, and I have always needed to use the non-reset device, even with the old USB stack. Hopefully a committer can pick this up and include an appropriate version of this fix to the source tree. In the mean time, if you are having trouble with a usb printer with -CURRENT, you may want to try this patch. I am attaching a patch file (referenced at /usr/src/sys/dev/usb/serial from my system. The change is to initialize sc_fflags to 0 when attaching the device. This is allowing open to stop returning EBUSY. Now on to finding out why using my newly accessible firewire disks resulted in filesystem corruption on all of my filesystems. I suspect some missing lock. Its very annoying, and I lost a lot of important files. (I will be doing a full backup of all of my disks before connecting my firewire disks back up). -Charles [-- Attachment #2 --] --- ulpt.c.orig (revision 190254) +++ ulpt.c (working copy) @@ -499,6 +499,7 @@ ulpt_attach(device_t dev) sc->sc_dev = dev; sc->sc_udev = uaa->device; + sc->sc_fflags = 0; device_set_usb2_desc(dev);help
