Thanks for the heads-up, I was no longer on the mailing list.
Unfortunately, on the first try it doesn't seem to be working. I'm
working off of latest git (52d4ba3). Without the patch, the taps
(there's only one on this particular board) are auto-detected:
$ src/openocd.exe -f tcl/interface/altera-usb-blaster.cfg

3000 kHz
Warn : no usb_blaster device description specified, using default 'USB-Blaster'
Error: Translation from khz to jtag_speed not implemented
Error: Translation from khz to jtag_speed not implemented
Error: Translation from jtag_speed to khz not implemented
Error: Translation from khz to jtag_speed not implemented
Info : interface specific clock speed value 2278080
Warn : There are no enabled taps. AUTO PROBING MIGHT NOT WORK!!
Warn : AUTO auto0.tap - use "jtag newtap auto0 tap -expected-id 0x0334917f ..."
Warn : AUTO auto0.tap - use "... -irlen 5"
Warn : gdb services need one or more targets defined
But with the patch, the interrogation fails ("all ones" or "all zeroes"):
$ src/openocd.exe -f tcl/interface/altera-usb-blaster.cfg

Putting the TAP declarations in the config file makes no difference.
This is with a USB Blaster clone (FT245+CPLD).
Anything in particular I should look at initially?
