Hi everyone I just sent in PR usb/112944, a patch to force uni-directional communication for the HP LaserJet 1010 (as recommended by Eygene Ryabinkin), since bi-di doesn't seem to work. Since I wrote this patch, I've heard that the Samsung ML-4600 laser (product ID 0x3004) also doesn't work properly in bi-di mode, at least with CUPS. What happens is that CUPS has a select() on the /dev/ulpt, and listens to see if there is data to read - when select() indicates that there is, CUPS reads, but hangs on read. Of course, forcing uni-direction communication fixes this problem.
I'm not sure if there is a deeper underlying problem here, so I'm not sure if this patch is appropriate? Ulrich Spoerlein <[EMAIL PROTECTED]> mentioned that the new USB stack (by HPS) works with the ML-4600, btw.
