I have a Prolific USB-Serial Controller which works on some USB ports with tip, but, not others. This is on a HP dv6000 laptop running up-to-date 6.2-stable with a custom kernel. This included all the devices found by GENERIC plus ucom and uftpi. I need to add uplcom, but, for now, I kldload it. I have included the output from "usbdevs -v" and the usb part of dmesg. If I use a port on the expansion tray, usb4, I sometines get uplcom_set_line_coding: IOERROR But, if I use a port on the laptop, usb0 or usb1, it works. I have a Prologix USB-GPIB adapter which works with open("/dev/cuaUx",O_RDWR | O_NOCTTY | O_NONBLOCK)) on either set of ports. If I connect the USB-Serial Controller to usb4, it does not work. If I connect it to usb0 or usb1 it works. I can not identify usb2 and usb3. The only differences I see is multiple translations to usb4. Any ideas? tomdean # usbdevs -v Controller /dev/usb0: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), \ Intel(0x0000), rev 1.00 port 1 addr 2: low speed, power 98 mA, config 1, USB Receiver(0xc517), \ Logitech(0x046d), rev 38.10 port 2 powered Controller /dev/usb1: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), \ Intel(0x0000), rev 1.00 port 1 addr 2: full speed, power 100 mA, config 1, \ USB-Serial Controller(0x2008), Prolific Technology Inc.(0x0557), \ rev 3.00 port 2 powered Controller /dev/usb2: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), \ Intel(0x0000), rev 1.00 port 1 powered port 2 powered Controller /dev/usb3: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), \ Intel(0x0000), rev 1.00 port 1 powered port 2 powered Controller /dev/usb4: addr 1: high speed, self powered, config 1, EHCI root hub(0x0000), \ Intel(0x0000), rev 1.00 port 1 powered port 2 powered port 3 powered port 4 addr 2: high speed, power 500 mA, config 1, \ USB 2.0 Camera(0x62c0), Sonix Technology Co., Ltd.(0x0c45), rev 2.10 port 5 addr 3: high speed, self powered, config 1, product 0x2507(0x2507), \ vendor 0x0424(0x0424), rev 0.00 port 1 powered port 2 powered port 3 powered port 4 powered port 5 powered port 6 addr 4: full speed, power 100 mA, config 1, \ Prologix GPIB-USB Controller(0x6001), \ Prologix(0x0403), rev 6.00 port 7 powered port 6 powered port 7 powered port 8 powered ===== From dmesg ====================================== uhci0: <UHCI (generic) USB controller> port 0x1820-0x183f \ irq 23 at device 29.0 on pci0 uhci0: [GIANT-LOCKED] usb0: <UHCI (generic) USB controller> on uhci0 usb0: USB revision 1.0 uhub0: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub0: 2 ports with 2 removable, self powered uhci1: <UHCI (generic) USB controller> port 0x1840-0x185f \ irq 19 at device 29.1 on pci0 uhci1: [GIANT-LOCKED] usb1: <UHCI (generic) USB controller> on uhci1 usb1: USB revision 1.0 uhub1: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub1: 2 ports with 2 removable, self powered uhci2: <UHCI (generic) USB controller> port 0x1860-0x187f \ irq 18 at device 29.2 on pci0 uhci2: [GIANT-LOCKED] usb2: <UHCI (generic) USB controller> on uhci2 usb2: USB revision 1.0 uhub2: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub2: 2 ports with 2 removable, self powered uhci3: <UHCI (generic) USB controller> port 0x1880-0x189f \ irq 16 at device 29.3 on pci0 uhci3: [GIANT-LOCKED] usb3: <UHCI (generic) USB controller> on uhci3 usb3: USB revision 1.0 uhub3: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub3: 2 ports with 2 removable, self powered ehci0: <Intel 82801GB/R (ICH7) USB 2.0 controller> mem 0xd8444000-0xd84443ff \ irq 23 at device 29.7 on pci0 ehci0: [GIANT-LOCKED] usb4: EHCI version 1.0 usb4: companion controllers, 2 ports each: usb0 usb1 usb2 usb3 usb4: <Intel 82801GB/R (ICH7) USB 2.0 controller> on ehci0 usb4: USB revision 2.0 uhub4: Intel EHCI root hub, class 9/0, rev 2.00/1.00, addr 1 uhub4: 8 ports with 8 removable, self powered ugen0: Sonix Technology Co., Ltd.
