I received a STM32-comStick today (STM32F107) but the accompanying
documentation (on CD) did not mention a JTAG port.
It has a micro-USB port (not mini, and comes without cable) and A connector.
I do not have the device. I believe that micro-USB port is the USB host/OTG port
and the A connector is the right one to use for debugging/programming.
OpenOCD seems to support the device STM32comStick.cfg but I could not
find a matching USB device.

I do not have this stick. Maybe the following discussion will help.

What does "lsusb -vvv" say? It is a bit strange that hiddev driver will
pick up this device. I assume that it is based on FTDI2232.
The STM32-PerformanceStick that I have uses a FTDI chip for debugging.
Here is the information from /proc/bus/usb/devices that I get on
Mandriva 2009.1
I tested it almost a year ago and it works fine with the proprietary
driver, I haven't tried it yet with the open source driver.
Hitex may very well have several versions for their USB debugging.
There is an interest in getting something faster than the ftdi device.
>From what Leon posted, his device may not be an ftdi but some
microprocessor.
