Hi, I have a Texas Instruments OMAP4440 connected via a USB cable to my laptop running FreeBSD 10.0-RELEASE amd64. This is the output of usbconfig -d 1.7 dump_device_desc: ugen1.7: <OMAP4440 Texas Instruments> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (100mA) bLength = 0x0012 bDescriptorType = 0x0001 bcdUSB = 0x0210 bDeviceClass = 0x00ff bDeviceSubClass = 0x00ff bDeviceProtocol = 0x00ff bMaxPacketSize0 = 0x0040 idVendor = 0x0451 idProduct = 0xd010 bcdDevice = 0x0000 iManufacturer = 0x0021 <Texas Instruments> iProduct = 0x0025 <OMAP4440> iSerialNumber = 0x0000 <no string> bNumConfigurations = 0x0001 For some reason, it repeatedly disconnects: ugen1.7: <Texas Instruments> at usbus1 (disconnected) ugen1.7: <Texas Instruments> at usbus1 ugen1.7: <Texas Instruments> at usbus1 (disconnected) ugen1.7: <Texas Instruments> at usbus1 ugen1.7: <Texas Instruments> at usbus1 (disconnected) ugen1.7: <Texas Instruments> at usbus1 These messages also appear in /var/log/messages: Sep 21 17:46:56 localhost kernel: ugen1.7: <Texas Instruments> at usbus1 Sep 21 17:46:56 localhost devd: Executing 'env LD_PRELOAD=/usr/local/lib/libhal.so:/usr/local/lib/libdbus-1.so:/usr/local/lib/libcuse4bsd.so /usr/local/etc/rc.d/webcamd start ugen1.7' Sep 21 17:46:56 localhost devd: Executing 'logger Unknown USB device: vendor 0x0451 product 0xd010 bus uhub3' Sep 21 17:46:56 localhost root: Unknown USB device: vendor 0x0451 product 0xd010 bus uhub3 Sep 21 17:46:59 localhost kernel: ugen1.7: <Texas Instruments> at usbus1 (disconnected) Sep 21 17:47:00 localhost kernel: ugen1.7: <Texas Instruments> at usbus1 Sep 21 17:47:00 localhost devd: Executing 'env LD_PRELOAD=/usr/local/lib/libhal.so:/usr/local/lib/libdbus-1.so:/usr/local/lib/libcuse4bsd.so /usr/local/etc/rc.d/webcamd start ugen1.7' Sep 21 17:47:00 localhost devd: Executing 'logger Unknown USB device: vendor 0x0451 product 0xd010 bus uhub3' Sep 21 17:47:00 localhost root: Unknown USB device: vendor 0x0451 product 0xd010 bus uhub3 Sep 21 17:47:03 localhost kernel: ugen1.7: <Texas Instruments> at usbus1 (disconnected) Sep 21 17:47:04 localhost kernel: ugen1.7: <Texas Instruments> at usbus1 Sep 21 17:47:04 localhost devd: Executing 'env LD_PRELOAD=/usr/local/lib/libhal.so:/usr/local/lib/libdbus-1.so:/usr/local/lib/libcuse4bsd.so /usr/local/etc/rc.d/webcamd start ugen1.7' The problem seems similar to this one: https://www.mail-archive.com/freebsd-usb@freebsd.org/msg08372.html Would it be possible to fix this?
