OK, here is what it gives: >sudo usbconfig -u 4 -a 3 dump_curr_config_desc ugen4.3: at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON Configuration index 0 bLength = 0x0009 bDescriptorType = 0x0002 wTotalLength = 0x0020 bNumInterfaces = 0x0001 bConfigurationValue = 0x0001 iConfiguration = 0x bmAttributes = 0x00c0 bMaxPower = 0x0001 Interface 0 bLength = 0x0009 bDescriptorType = 0x0004 bInterfaceNumber = 0x bAlternateSetting = 0x bNumEndpoints = 0x0002 bInterfaceClass = 0x0007 bInterfaceSubClass = 0x0001 bInterfaceProtocol = 0x0002 iInterface = 0x Endpoint 0 bLength = 0x0007 bDescriptorType = 0x0005 bEndpointAddress = 0x0002 bmAttributes = 0x0002 wMaxPacketSize = 0x0200 bInterval = 0x000a bRefresh = 0x bSynchAddress = 0x Endpoint 1 bLength = 0x0007 bDescriptorType = 0x0005 bEndpointAddress = 0x0081 bmAttributes = 0x0002 wMaxPacketSize = 0x0200 bInterval = 0x000a bRefresh = 0x bSynchAddress = 0x I don't know where to look for the right endpoint here... But I tried every endpoint - /dev/usb/4.3.0, /dev/usb/4.3.1 and /dev/usb/4.3.2 - and the last one worked. So, the problem is solved for me. Just for my curiosity, where can I read more about USB endpoints?

usb printer rejects incoming data
Hello all, Recently I upgraded to the latest RELENG_8 and rebuilt world. Now I'm having strange problems with my USB printer (Samsung CLP 315). Digging into it these last days, I found that it seems to refuse incoming data via USB port. I'm using foo2qpdl filter and it generates a standard QPDL stream for that printer, the problem occurs when I try to feed that data to the printer. Here is some details about my environment: >uname -a FreeBSD ..net 8.0-PRERELEASE FreeBSD 8.0-PRERELEASE #26: Sun Nov 15 15:44:11 CET 2009 r...@..net:/usr/obj/usr/src/sys/ERLEY i386 >sudo usbconfig ugen0.1: at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen1.1: at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen2.1: at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen3.1: at usbus3, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen4.1: at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON ugen4.2: <802.11 bg WLAN Ralink> at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON ugen0.2: at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen4.3: at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON ugen1.2: at usbus1, cfg=0 md=HOST spd=LOW (1.5Mbps) pwr=ON >sudo ls -l /dev/u* | grep 4.3 lrw-rw-rw- 1 daemon daemon 9 16 ноя 14:07 /dev/ugen4.3@ -> usb/4.3.0 crw-rw-rw- 1 daemon daemon 0, 140 16 ноя 14:07 4.3.0 crw-rw-rw- 1 daemon daemon 0, 142 16 ноя 14:07 4.3.1 crw-rw-rw- 1 daemon daemon 0, 143 16 ноя 14:07 4.3.2 >sudo cat tiger.qpdl > /dev/usb/4.3.0 cat: stdout: Input/output error I'm sure this file tiger.qpdl contains the data needed, I created it from /usr/local/share/ghostscript/8.64/examples/tiger.eps using gs + foo2qpdl and tested on another PC.
