Martin Kaiser lists at kaiser.cxDear all, I'm struggling to get started with a 1.1p board. When I connect it via USB (with no simcard inserted and no connection to a phone), the red led is on. Sometimes, both leds remain off after connecting the board when I have a simcard inserted and a phone connected. On one box (debian lenny), the board is never recognized by lsusb or kernel messages. Do I need anything special (other than basic usb support) compiled into the kernel for libusb to do its work in user space? I tried dfu-util -l, the board wasn't listed. On a second box (debian squeeze) there's log messages when the usb is connected Feb 15 22:34:44 greta kernel: [186232.651806] usb 1-1.1: new full speed USB device using ehci_hcd and address 13 Feb 15 22:34:44 greta kernel: [186232.745566] usb 1-1.1: New USB device found, idVendor=16c0, idProduct=0762 Feb 15 22:34:44 greta kernel: [186232.745573] usb 1-1.1: New USB device strings: Mfr=4, Product=5, SerialNumber=0 Feb 15 22:34:44 greta kernel: [186232.745577] usb 1-1.1: Product: SimTrace SIM Sniffer - Runtime Mode Feb 15 22:34:44 greta kernel: [186232.745581] usb 1-1.1: Manufacturer: sysmocom - systems for mobile communications GmbH Feb 15 22:34:44 greta kernel: [186232.745694] usb 1-1.1: configuration #1 chosen from 1 choice lsusb doesn't show anything either the red led is on after connecting, simtrace (linked against libusb-1.0) says "can't open USB device" After some more tries, dfu-util recognizes the board root at greta:~# dfu-util -l dfu-util - (C) 2007-2008 by OpenMoko Inc.

I tried resetting the board with the bootloader button pressed, this didn't change anything. While trying to flash the firmware, there was no sim inserted and no phone connected. Does anyone have an idea what else I can try to track down the problems and get the board up and running? Thanks in advance, Martin
