    Make sure you are using a version of CrossWorks that supports the -H devices - looking at the release notes, this was supported from version 2.1.0 onwards.

    Thanks.  I had 2.0.11 installed.  Just downloaded/installed 2.2.0 and submitted the request for a trial license.  When it arrives I'll let you know if this fixes the problem.

    Good news... I finally got the Olimex ARM-USB-OCD-H to connect to my target.  It took several steps to get it to work, the first being to download/install a newer version of CrossStudio.  That let CrossStudio find the ARM-USB-OCD-H.  Then I had to get all the jumpers om my KEIL MCB2130 board set up right.  That got me to a "read error" when I tried to connect to the target.  Then I tried slowing down the JTAG clock divider, but that didn't work.  Eventually, I cycled power on my board, then unplugged the ARM-USB-OCD-H temporarily, and tried again.  This yielded quite a surprise as I got an error message that the FTDI drivers could not be found.  Shocking.  I tried again and viola --- I saw "Connected target interface "Olimex ARM-USB-OCD" in the status bar.  Hooray!  I was able to use the debugger to load code, step through it, etc.  Good news.

    ARM-USB-OCD-H is supported by v2.0.7.2, you may need to follow instructions here and set it up manually after installing the driver of course.

    I have used the libUSB driver, and all has worked fine.
