Aside from hacking ulpt.c, is there any way to tune the USB latency? More... I have a USB printer, which works, but it takes about 2 minutes before FreeBSD 7.2 will send it ANY data...during that 2 minutes nothing is hapenning. It's not a printer warmup issue either, or a cable or anything like that, as it worked on FreeBSD 6.1 (after applying a patch to ulpt.c as submitted by someone on this list. (You know who you are! Thanks!) For lack of a better term is there a, "don't wait 2 minutes before you decide the printer is probably not up to USB spec and start talking to it anyway" sysctl or something? -Modulok-
