Hi!
i've got some problems with openocd when using an Altera USB-Blaster.
I build openocd with libftdi. (When I use the FTD2xx driver I get the
same results..)
When I start openocd i get the following output:

when i disconnect and reconnect the Altera USB-Blaster before I start
openocd, I get the following output:

-------------------------------------------------------------------
Is it possible, that there is a problem with the reset of the USB-Blaster?
Or is there a problem with the jtag speed?
Any suggestions what I can do to get it run?
Regards!
Stefan
